Takes Care of Two Things at Once: Composting Food Waste
Years ago my dad taught me the benefits of composting food waste. It had nothing to do with any type of “green” movement or being environmentally friendly, no, it had everything to do with reintroducing nutrients back into the soil.
Here is what he taught me then and it still holds true today. By burying your food waste and kitchen scraps (no steak bones though), you are providing a quality food source for the creatures that live in your soil. From micro organisms and those creatures that the human eye can not see, up to worms, which of course we do see.
See, what happens is these creatures eat the food (and of course each other) and then finally the worms eat basically everything and their castings (worm poop) create the best nutrients your soil could ever have. By continually supplying your garden soil with food waste you are feeding the earthly creatures and they reward you with healthy soil. Now where can you get a trade off like that!
Ok so here is how you do it. Get yourself a fairly large Tupperware bowl. One large enough to hold at least a week’s worth of food scraps. Then after each meal dump everything and anything into that bowl. Just do not put steak bones in there, they wont biodegrade or be eaten by the worms. Banana peels, apple peels, coffee grinds, fish, vegetable scraps, egg shells and basically anything you don’t eat, all qualifies.
When your Tupperware bowl gets full, take it out to your garden and dig a hole about a foot to two feet deep and then dump the food scraps into the hole. Fill in the hole with the dirt and mark the spot with a stick or something else so that you do not dig up that area again for another three months. You need to give those little rascals some time to eat it all.
Now you simply repeat this process as the Tupperware bowl gets full. If you find that you live in colder climates where the ground may freeze for lengthy periods of time, then consider starting a warm box to recycle your food scraps. That goes beyond the scope of this article but I am sure if you Googled the search term “vermicompost” you will get all the information you will ever need.
So what are the two things I was talking about earlier? Well obviously the first is you are adding nutrients to your soil through composting food waste. The second is by composting your food waste you are limiting the amount of garbage that ends up in a landfill. The average four person house hold creates about 8 pounds of food waste per week. If every family in America followed this process we would eliminate nearly one billion pounds of food waste garbage a year. Now that is a lot of trash!
Do your part and compost your food waste. The worms in your garden will love you for it and so will everyone else in the environment.

How it Will Benefit Us All: Gasification
If you search for gasification and terms like “wood stove†on video sharing sites these days you will see demonstrations of wood being burnt in little stoves which seem to something almost miraculous and quite different from our idea of wood as a fuel. These little boilers light rapidly, produce no detectable smoke after the initial lighting and firing, and burn very hot.
So what is the technique which is being used, and how might it help us all in weaning society off fossil fuels?
What you have seen is a method of gasification. It differs from combustion in that it uses just 20% to 30% of the air or oxygen necessary for complete fuel combustion. During gasification, the amount of air supplied to the gasifier is carefully controlled with the effect that only a small part of the fuel burns completely. Trials of this process have illustrated that up to 70% of the energy value of the fue used can be recovered as what is known as synthesis gas, or syngas. This producer gas can also be used for various applications similar to natural gas.
This is a part of the magic, and not one really shown in the YouTube type videos, but it makes this method even more useful. This is due to the fact that syngas can be put to useful work, in both drying the feed fuel prior to gasification and after collection and storage it can be used as a fossil fuel replacement, and renewable energy source. When a gasification plant also includes Combined Heat and Power (CHP) and/or electricity export from the site, the gains are even more impressive.
Gasification in addition promises to be the most efficient long-term solution for capturing carbon while utilizing these valuable feedstocks, and storing the CO2 for very long priods, to reduce or halt global warming.
Gasification of wood and wood-type residues and waste in fixed bed or fluidised bed gasifiers with subsequent burning of the gas for heat production is has become state of the art with designers of thes systems working hard to gain the absolute maximum efficiency out of these systems.
These wood gasifiers which are located primarily in the Scandinavian countries are used almost entirely for space heating heat generation. Gasification of biomass is the renewable fuel system preferred by many, and can be defined as the thermal conversion of solid biomass to gaseous fuel.
Gasification has been around for over a hundred years, but the benefits of biochar are only now being discovered. Furthermore, it is still a wide-open field.
Before electric lighting was available in cities there were street lamps fuelled by gasified coal. It is easy to forget that the process has been reliably used on a commercial scale worldwide for more than 50 years in the refining, fertilizer, and chemical industries, and for more than 35 years in the electric power industry. More than 75 companies involved in the development, licensing, and use of these technologies as well as engineering, construction, equipment manufacturing and production of synthesis gas by gasification from coal, petroleum coke, heavy oils and other hydrocarbons.
Gasification has been proven to be a viable technology for CO2 capture and reducing SOx, NOx, particulate matter, and mercury emissions from coal and petcoke-fired power plants, synthetic fuels production, and chemical facilities.
Plants in this category have been capturing carbon dioxide for several decades in chemical plants in China and the United States. It also has potential contributions to make to both transportation and electrical power energy markets. With ongoing concerns about the price and availability of oil, populous countries like the U.S. gasification has proven to be in high demand and quite successful. However, it can also be used in conjunction with gas engines and gas turbines to obtain a higher conversion efficiency than conventional fossil-fuel electric power generation. Gasification can help meet renewable energy targets, address concerns about global warming, and contribute to meeting global environmental targets.
Steve has built a great web site where there is a lot more information about gasification. This is a hot subject indeed for this technology which has become an essential read for all those in alternative energy and interested in taking action to reduce the impact of climate change.

Green Tip – Moms Use Clothe Diapers
Sure, this is a little messier than the easier, disposable version. However, do you even realize the amount of disposable diapers that are filling landfills?? Cloth diapers are a choice that every mother should seriously consider. Let’s look at some facts that are quite alarming…
Disposable Diapers Sobering Facts:
* from birth to about 2-1/2 the average child will go through about 7,300 diapers
* the cost for that is about $2600
* 18 billion diapers enter landfills each year
* disposable diapers make up about 3.4 million tons of trash
* health risks such as fertility issues in males, eyes, nose and throat issues and even asthma-like symptoms have been connected to disposable diapers!
* long term negative affects on animal and water life.
* the chemicals that make disposable diapers white increase the risk of cancer
* affect development
* they use more water. yep. you may need to wash cloth diapers, however, way more water is used making disposable diapers!
* a study, conducted by Anderson Laboratories in 1999 and published in the Archives of Environmental Health, found that disposable diapers release chemicals called volatile organic compounds (VOCs), including toluene, ethylbenzene, xylene and dipentene. They have been shown to have toxic health effects, such as cancer and brain damage, when used over time or high exposure.
* they use 1.3 million tons of wood pulp. that’s about 1/4 million trees every year.
* they take up to 500 years to break down.
* more viruses than you want to know about…including polio, survive for two weeks or more after disposed of.
There are many many many more reasons to avoid disposable diapers. However, I think our readers are intelligent and the above information is enough to get you thinking! Research for yourself. You will be shocked!
Go for organic natural reusable cloth diapers. You will not only be helping the environment and saving money, you will also protect your sweet precious love bugs from harm!

Helping Kids Care For the Earth – Ideas For Earth Day and Beyond
Earth Day is April 22, and while it’s important to get involved on this day, there are things we can do as families that will make a huge impact throughout the year.
It starts with helping our kids to celebrate the world in which we live, and it continues with helping them to love it so much that they want to do everything they can to help protect it. Here are six ideas to help your kids celebrate and care for our earth:
1. Get out and enjoy it. Researchers are now saying that simply getting kids outside in nature may be the most effective way to raise their awareness of environmental issues. Suddenly, these problems that they hear about on the news and in the classroom have a real impact on their daily lives. They see firsthand how a forest or a beach or a tidepool or a meadow is teeming with life, with ecological relationships that are interdependent, delicate and complex.
To encourage your kids to get out there and enjoy the natural world, you may have to purposefully inject some extra excitement in the idea, but just at first. Take your dog (or a friend’s dog) for a walk in the woods. A dog’s love for nature, and subsequent enjoyment of it, is infectious. Create a list of things to find and make your adventure into the outdoors into a scavenger hunt.
If possible, and if your kids are old enough to be by themselves out there, find a safe place for them to play in a natural environment. Allow them to go there to get away, to sit and think or to talk with their friends. Make a point to get the kids out in nature every day. Better yet, go with them.
2. Watch “An Inconvenient Truth” as a family for inspiration. Invite some of your children’s friends over to watch it with their parents and talk about some initiatives that you can each commit to or some larger projects that you can work on as a neighborhood or community.
3. Help your kids learn about endangered animals. Together, look into organizations that help endangered animals and see how you can get involved.
4. Reduce and re-use, then recycle. Lots of kids get excited about recycling. Fewer are into reducing or re-using. Model to your children a healthy pattern of consumption. Talk frequently about the many benefits (which go way beyond environmental) of living a simple life and of being wary of a lifestyle of mass consumerism. As kids spend more time outside and less time at the mall or watching television advertisements, this shift may feel increasingly more natural to them.
5. Teach your kids about potentially harmful chemicals and how they can be everywhere in our world: in the foods we eat, in the supplies we use to clean the house, in our paint, in our cosmetics, in our lawn care products. Turn the search for these things into a game and allow your kids to be detectives, learning about and seeking out these harmful chemicals and then finding natural alternatives.
6. The next time you take the kids to the grocery store, see how you can minimize the amount of packaging that you purchase. We have been known to purposefully not purchase an item because of the manufacturer’s use of wasteful packaging. It won’t take long for the kids to realize that the best item in the store for minimal packaging: raw fruits and vegetables.
In our family, the more we can make these life changes into a game, the more apt the kids are to follow suit. Help your kids to understand how one person really can make a difference (especially when that person is part of a committed family or group) and review often the personal impact that you all have made.

5 Steps to a Greener Life
Lots of people talk about trying to live a greener life, with some even going so far as to completely change their lifestyle, but most people aren’t sure how to go green because they don’t know exactly what that means. Sure, most people know the basics that scratch the surface such as reusing, recycling and reducing the amount of waste output for their homes but there many other steps you can take to move towards a cleaner, greener environment.
If you’re wondering how you can make your life greener, here are five different tips that are simple and easy to implement and that don’t cost the you anything. All it takes is a little dedication and after a few months, these five little things will become second-nature to you.
1. The next time you go shopping use cloth bags at the grocery store instead of paper or plastic. These cloth bags can be purchased for as little as a few dollars each and they’re much stronger than paper or plastic bags and will last you through years of use.
These bags help reduce waste since most people throw away the plastic and paper bags. The hardest part of using cloth bags is remembering to take them to the store, but once you get in the habit of using them, it becomes unconscious habit.
2. Replace your standard light bulbs with compact fluorescent bulbs. These bulbs use less energy and last for four to five years, almost 15 times longer than traditional bulbs. While the cost of a compact fluorescent bulb is more than your standard bulb, they easily pay for themselves over time requiring less frequent replacement and reduced energy consumption. In fact, studies show that a CF bulb can actually pay for itself within one to two months. One CF bulb also saves about five pounds of greenhouse gas carbon dioxide a month. Replacing every bulb in your home can have a huge impact on the environment and on your wallet.
3. Use public transportation. By car pooling, taking the bus, or using the subway you can cut down on the amount of gas you use and the amount of exhaust your car emits. While it may be an inconvenience in some ways, it is one of the best ways of helping the environment. Even better, walk or ride your bike to work if possible. This not only saves you money and helps the environment but it also keeps you fit and healthy!
4. Adjust your thermostat by a few degrees. By turning your thermostat down by just two degrees in the winter, you can save over 50 pounds of greenhouse gas carbon dioxide per month while lowering your heating bill. Turning it up a few degrees in the summer can likewise save you money and save the environment.
5. Finally, only wash your clothes or run your dish washer when you have a full load. It wastes water and electricity to wash and dry only a few pieces of clothing. In fact, if you can, try to wash your clothes using the cold water cycle as it uses up to 50% less energy than a warm water one.
By just doing these basics not only you can save some serious money but you can rest assured that you’re doing your part for a cleaner, brighter future. To discover more ideas you can use around your home for living green visit http://www.greentipsforyou.com!

A Change in Krill Ecosystem
Antarctic Peninsula has been experiencing warming trends for over 40 years with an increase of 2-3 C, thus correlating with lower sea ice conditions in the Amundsen Sea and Bellinghausen Sea. Warming temperatures around the Antarctic Peninsula is changing the dynamics of the ecosystem. The rise in atmospheric temperature is causing increasing in melting of freshwater glaciers and ice shelves. Fresh water emerging into the sea counteracts the salinity within a regional area. Changes identified are;
• Decrease in sea water salinity up to 60 miles offshore
• Lower sea ice
• Decreased krill population
• Increased salp (open ocean tunicate that is reminiscent of a jelly-fish) population
• Increase in cryptophytes (single cell phytoplankton algae)
• Decrease in diatom phytoplankton
• Increase in carbon sequestering in deep ocean sinks
• Decrease in carbon availability in the food chain
The Antarctic Krill (Euphausia superba), a small shrimp like crustacean is the most important zooplankton species associated with the sea ice and plays a crucial role in the Antarctic food web. On a regional basis the amount of krill appear to be declining in the southern ocean. There are definitely lower trends in krill population during lower sea ice years around Antarctica. Part of the rational for the population decline is that ice algae rely on the sea ice for protection and growth. The krill need the sea ice in order to feed on the algae and phytoplankton.
Krill occur in groups or large swarms. They are less than 3 inches in size and feed primarily on phytoplankton and sea ice algae. Krill filter diatom phytoplankton out of the water column and scrape algae from the sea ice. Apart from frequenting the sea ice to feed, krill in particular juveniles, seek protection from predators in the many nooks and crannies formed by the deformed sea ice floes. Krill is the staple food of many fish, birds and mammals in the Southern Ocean. The biomass of Antarctic krill is considered to be larger than that of the earth’s human population.
Sea- ice algae utilizes atmospheric carbon dioxide for its energy source, the same as plants do on land. Krill diet of the sea-ice algae and phytoplankton is essential for converting the carbon for use in higher animals such as fish, birds, and whales. This carbon conversion is a very critical role in predatory nutrition. Additionally krill do eliminate some of the silica from the diatom shells and carbon in sticky balls that sinks nearly two miles into the deep ocean. These cold, deep waters are able to contain carbon dioxide and prevent the gas from rising to the surface, thus immobilizing carbon that is not passed into the food chain.
In recent years there have been increases in algae phytoplankton called cryptophytes. Mark Moline, California Polytechnic State University, states that the cryptophyte population correlates with warmer temperatures and lower salinity waters that are produced by the melting of the freshwater glacier. Cryptophytes measure around 2 mm, while other plankton in the Antarctic waters are much larger and measure 15 to 270 mm. Along with the increase in cryptophyte population an increase in salp, a pelagic tunicate, population has also occurred. There are differences between salps and krill. Salps feeding efficiency is capable of grazing on smaller food sources less than 4mm, whereas, the Antarctic Krill efficiency declines on any food less than 20 mm. The salps compete with krill for the phytoplankton and thus decrease the krill population. Additionally the salps feed on krill larvae, which also cause a decline in krill numbers.
The warming trend in the Antarctic Peninsula is showing a pattern of increasing cryptophytes over other phytoplankton and the increase in the salp. This influence is due to the low sea ice and the lowering of the salinity in the seawater. Salps and cryptophytes do better in the lower salinity, while the krill and other plankton are unable to tolerate the increased freshwater regime from the glacier ice melts. This selectivity gives preference to the salps as the dominant species while decreasing krill abundance. During lower sea ice seasons the density of krill declines while the salp population increases.
Carbon sequestering into the deep ocean from the algae and phytoplankton occur by both the salp and krill. Both species eliminate the atmospheric carbon received from the primary producing algae by producing fecal pellets by the salps and sticky balls by the krill, thereby, reducing the amount of carbon dioxide in the atmosphere. The salps though sequester more carbon into the cold deep ocean than the krill. However, the krill provides the most efficient pathway for carbon transfer up into the food chain. The cryptophyte dominated waters are less efficient in the food chain due to increased feeding by salps and the difficulty of the krill to utilize the cryptophytes as a food source. Migration patterns by penguins are changing, in part due to the changing krill population. Krill is a mainstay diet for penguins, and if the krill population changes, many other ecological changes occur with it.
Steve Bynum has worked at Palmer Station along the Antarctic Peninsula. He not only enjoyed the ecosystem along the Bellinghausen Sea but he has also witnessed the changing climate conditions.

Help Save the Environment by Recycling Cans
I like walking. Whenever I can I leave the car at home and walk. I walk to the shops, to the library, and many other places as well. Every day I see used aluminum drinks cans dropped on pathways and in hedgerows. If people want to dispose of them this way at least drop them where they can easily be picked up by someone else, and not in a hedgerow or other difficult spot where it is easy to be scratched and prickled by thorns.
Many people have a twinge of conscience about the environment and what we can do voluntarily to help save it. Recycling cans is what we can do easily. All you need do is separate them from the rest of the rubbish and either take them to a recycling centre or leave them in your “recyclables” bin, to be collected by, in our case, the local council.
The one thing we must not do is put them in landfill, because they don’t biodegradable.
Instead of throwing away empty aluminum cans away here are four ways to reuse them.
1. Used ring pull cans could be used as a miniature vase for a flower or two.
2. Rinse out used cans and use them in the garden shed for storing small items such as nails and washers.
3. You could use an old can to practice your putting. Take it to the office and put it on the floor any time you want to practice your putting.
4. Rather than leave your pens and biros scattered all around the house why not put them all together in a used can.
This is just four ideas of what to do with used empty cans. You might well be able to think up many more ideas for recycling cans.

Environmental Improvements – Calling Leaders
The environment, which its current emphasis on ‘Global Warming’ and ‘Climate Change’ important though it is, is not the most vital matter facing humanity.
During recent speaking and teaching visits to Uganda and Kenya, and hearing something of the actual situation, I have become angry and occasionally tearful at the gross injustice, greed and corruption which is rife.
Our world has become so unstable over these past months in a way totally unpredictable by man. If I had written prophetically, 15 months ago, about what we are presently experiencing in the area of finance, you would have said I was off my head and just daft!
The Carbon Footprint issue might be causing some environmental damage although is being question by many, but the financial greed and mismanagement footprint is hurting millions as people loose income, jobs, houses and basic security.
When I was in Kenya last November, I was informed that the economic problems hitting America and Europe would hit Africa in three months time, and visiting schools and orphanages in the various slum areas I was very much aware of how a little extra resources could help so many more people with very little effort.
The structures are in place to utilise and distribute AID in a responsible manner. I have seen the projects designed to help those whose lives are confronted with unnecessary suffering, one example of this in Methere in Nairobi and the River of Life School in Manyatta, Kisumu. Now, there are other projects and schemes in various other nations and by investing in these immediately, the environment would improve slightly within a few months, but for the people who live there the improvement would be immense.
I write this as the G20 Summit is meeting in London. The money spent on that alone could feed the poor in Kenya (or some other nation) for months. It is just that I know a little about Kenya.
Earthquakes, floods and droughts will continue, and these will undoubtedly increase, with environmental disaster and tragedy resulting, but what concerns me is the area where substantial and significant improvements could be made, if only leaders would make sensible wise decisions.
You see, I write as a committed disciple of Jesus Christ, and I am not given the option of being quiet on these issues.
One sentence really challenged me this week. If you were reading the Sermon on the Mount for the first time, in Matthew’s Gospel, Chapters five to seven, how would you change your life?
How might this motivate us in the areas of fresh water and sewers, immunisation and basic health services, and feeding programmes and education for those who genuinely want to study and contribute positively towards the welfare and well-being of their nation.
To make these environmental improvements, strong, radical leadership will be required, but it is often in times of real darkness that the risen and living Lord Jesus Christ chooses, redeems, and raises up a leader or leaders to shepherd people out of their predicament.

Gasification Sees a New Dawn and How it Will Benefit Us All
If you search for gasification and terms like “wood stove†on video sharing sites these days you will see demonstrations of wood being burnt in little stoves which seem to something almost miraculous and quite different from our idea of wood as a fuel. These little boilers light rapidly, produce no detectable smoke after the initial lighting and firing, and burn very hot.
So what is the technique which is being used, and how might it help us all in weaning society off fossil fuels?
What you have seen is a method of gasification. It differs from combustion in that it uses just 20% to 30% of the air or oxygen necessary for complete fuel combustion. During gasification, the amount of air supplied to the gasifier is carefully controlled with the effect that only a small part of the fuel burns completely. Trials of this process have illustrated that up to 70% of the energy value of the fue used can be recovered as what is known as synthesis gas, or syngas. This producer gas can also be used for various applications similar to natural gas.
This is a part of the magic, and not one really shown in the YouTube type videos, but it makes this method even more useful. This is due to the fact that syngas can be put to useful work, in both drying the feed fuel prior to gasification and after collection and storage it can be used as a fossil fuel replacement, and renewable energy source. When a gasification plant also includes Combined Heat and Power (CHP) and/or electricity export from the site, the gains are even more impressive.
Gasification in addition promises to be the most efficient long-term solution for capturing carbon while utilizing these valuable feedstocks, and storing the CO2 for very long priods, to reduce or halt global warming.
Gasification of wood and wood-type residues and waste in fixed bed or fluidised bed gasifiers with subsequent burning of the gas for heat production is has become state of the art with designers of thes systems working hard to gain the absolute maximum efficiency out of these systems.
These wood gasifiers which are located primarily in the Scandinavian countries are used almost entirely for space heating heat generation. Gasification of biomass is the renewable fuel system preferred by many, and can be defined as the thermal conversion of solid biomass to gaseous fuel.
Gasification has been around for over a hundred years, but the benefits of biochar are only now being discovered. Furthermore, it is still a wide-open field.
Before electric lighting was available in cities there were street lamps fuelled by gasified coal. It is easy to forget that the process has been reliably used on a commercial scale worldwide for more than 50 years in the refining, fertilizer, and chemical industries, and for more than 35 years in the electric power industry. More than 75 companies involved in the development, licensing, and use of these technologies as well as engineering, construction, equipment manufacturing and production of synthesis gas by gasification from coal, petroleum coke, heavy oils and other hydrocarbons.
Gasification has been proven to be a viable technology for CO2 capture and reducing SOx, NOx, particulate matter, and mercury emissions from coal and petcoke-fired power plants, synthetic fuels production, and chemical facilities.
Plants in this category have been capturing carbon dioxide for several decades in chemical plants in China and the United States. It also has potential contributions to make to both transportation and electrical power energy markets. With ongoing concerns about the price and availability of oil, populous countries like the U.S. gasification has proven to be in high demand and quite successful. However, it can also be used in conjunction with gas engines and gas turbines to obtain a higher conversion efficiency than conventional fossil-fuel electric power generation. Gasification can help meet renewable energy targets, address concerns about global warming, and contribute to meeting global environmental targets.
Steve has built a great web site where there is a lot more information about gasification. This is a hot subject indeed for this technology which has become an essential read for all those in alternative energy and interested in taking action to reduce the impact of climate change.
