The Hundred Mile Challenge

food-productin.jpgThere’s a brand new way to eat for anyone concerned about the environment and the advantages are many. I’m talking about the hundred mile diet plan and this is one diet that isn’t a fad. If you’ve never heard of the hundred mile diet, it is a new eating plan based on eating foods produced within one hundred miles of your own home. This is a greener alternative to the way we eat now, where the typical meal ingredient has been shipped 1,500 miles to make it to our plates. The most exciting aspect of this diet is the fact that it is a simple and fun way to help the environment.

How it works --- The hundred mile diet is a way to get people to eat foods grown and produced locally. This may sounds limiting, but it’s a lot easier than some people think. The diet plan includes anything that is produced within 100 miles of your home. This includes any food group within your area and with a little research you may find some things that will surprise and delight you. For example I recently found out that the Kellogg’s cereal factory is within my area. I also found a fresh fruit and vegetable stand within the hundred mile limit from my home and found seasonal berries, meat, cheese, bread, wine, and basically anything else you can think of all produced within a hundred miles of me. The results will be different for different areas but people across the country who have taken this challenge have found a lot more than they would have expected.


Starting With Solar

Most of us cannot feasibly afford to install a full solar power system into our homes. Energy Refuge suggests starting small. One solar panel and a sealed battery would hold about 400 watts of electricity. You will also need a charge control, power inverter, and a voltage meter. That is enough to run some of your small appliances, and will offset the cost of the solar panel. Here is a tutorial, put together by Energy Refuge on how to build a basic solar power generator.

If you are not comfortable starting from scratch, then have a look at this kit, by the 'Go-Solar' Company. Reasonably priced especially when you consider the savings on your electrical bill. Five hours of sun per day and a 20 watt solar panel will give you 100 watt-hours of energy. To store more electricity simply purchase a larger battery.


Global Warning - Shift of habitats

The impact of global warming is not just restricted to increasing levels of sea water and climate changes but also to shifting of habitats by various species of animals. Studies conducted in the mountains of Madagascar through light on this new development.

Animal species that live on the lower slopes of the mountains of Madagascar’s Tsaratanana Massif, have shifted base upwards on account of increase in global temperatures. Research indicates that this is the recipe needed for extinction of these animals. The animals shifting up will be living in close proximity to each other near the summit of the mountains and the magnitude of these shifts will combine together and cause extinction of entire species of animals. The extinction of 3 species of reptiles and amphibians found in Madagascar’s mountainous regions is predicted between the periods 2050 to 2100. Global warming will be squarely responsible for such a disaster.


Dam Rumbles

The Yangtze River is one of the longest waterways in the world. Stretching more than 6,300 kilometres from Tibet to the East China Sea, the river has played an important role in China’s history, growth, and economy. The Three Gorges region is characterized by steep rocky cliffs - reaching up to 1,500 metres above the water - bounding a narrow stretch of the Yangtze. The river runs torrentially through this channel, flowing into various topographical regions that include twists, calm stretches, and shoals. Famously, it is also home to numerous archeological sites.

The Three Gorges Dam has made headlines since the plan was first unveiled. The huge scale of the project has attracted a lot of attention.


What is carbon foot print and how can I reduce it??

A Carbon footprint is a rough measure of green house gas emissions in the atmosphere by human activity. It is measured in terms of units of carbon dioxide (CO2). On an average, each individual has a carbon footprint of approximately 8 tons annually. Carbon dioxide is produced from every human activity right from cooking, leaving lights on, driving a car and refrigeration, to throwing a wrapper on the streets. Almost every one of our activities results in carbon emissions. All these seemingly inconsequential acts add up rapidly, thus contributing to global warming, which is one of the greatest threats faced by the planet today. Principally, a carbon footprint is the amount of fuel consumed by an individual in a span of one year. The concept of the carbon footprint is essential to understand the impression that personal comportment has on the atmosphere and on global warming.


Ancient Microbes Could Help Produce Biofuels

Grand_prismatic_spring.jpgProducing ethanol from the cellulose in plant material may end up being be a part of the solution to humanity's energy woes, but right now the process is expensive, slow and inefficient. Now researchers at the Sandia National Laboratory in Livermore and UC Riverside are trying to draft some of the earth's oldest inhabitants into service for the cause. They're working with ancient microbes known as archaea, which live in some of the most hostile environments on the planet, such as hyper-saline lakes, acidic hot springs, and near-boiling deep ocean vents. They found that one strain, discovered in an Italian volcano, produces enzymes that break down the cell walls of plants, releasing the sugars within that can then be converted into ethanol. Now the scientists are working on improving the efficiency of the enzymes' activity, to make fuel production viable.


Brazil's New Maps Show Where the Amazon is in Trouble

Amazon_rainforest.jpgThe government of Brazil has just released new maps that show where the Amazon is most at risk, and why.  The maps shop the effects of deforestation, mining, cattle ranching and crop expansion.  Cattle ranching and soy farming have been the biggest threats to the region, officials say.  Once roads are built to serve those land uses, the timber industry follows right on their heels.  The maps show data from as recently as 2003.

Efforts to protect the North Atlantic Whale

Around 1000 square nautical miles, in the Roseway Basin situated close to Barrington, NS, that is the beat of the North Atlantic Whale has been made a ‘ship free zone’. This is one of the last-ditch attempts to save the North Atlantic Whale or the ‘right’ whale, from dying out. There are only around 350 of them left and such an effort is vital to their survival, otherwise the species will die out by 2020.


Cork - A Renewable Resource

These days, there are more reasons to choose cork. From cork flooring to fishing floats, cork has been experiencing a surge in popularity. However, one traditional use of cork has been in decline. Once the material of choice for bottle stoppers or ‘corks’, synthetics now vie with natural cork.

Cork comes from the cork oak, an evergreen. It is made up of a waxy material called suberin, giving very elastic and impermeable properties. It is also low-density and naturally fire-resistant. These characteristics have made it useful for a wide variety of products, including musical instruments. Cork’s environmentally friendly qualities are also appealing: it is easily recycled and results in few damaging by-products.

The Worldwide Fund For Nature (WWF) is calling for an expansion of Portugal’s cork forests.

Did you know that tobacco smoke coupled with a toxic gas which is present in air pollution is responsible for tuberculosis infection? Actually this was only recently established, so how would we know. But it sure makes us wanna think about things seriously.
