It doesn’t take a genius to figure out that cutting down trees adds to the carbon that’s put in our atmosphere. Almost 33 million acres of forest are cut down every year; foresters cutting down tropical forests contribute to 1.5 billion metric tons of carbon alone- some 20% of all green house gases put into the atmosphere. It’s said in the article that if it was to be cut in half it could save 500 million metric tons of carbon annually and contribute 12 percent of the total reductions in green house

Save the planet Greenhouse gases and carbon emission are released into the air by things we do every day. For example‚ cars‚ turning on light switches and even something as simple as leaving your stereo or computer on overnight. The atmosphere has a natural supply of "greenhouse gases." They capture heat and keep the surface of the Earth warm enough for us to live on. Without the greenhouse effect‚ the planet would be an uninhabitable‚ frozen wasteland. Everyone creates a carbon footprint that measures

11% of combined pesticide residuals come from the growing of vegetables‚ fruits and grains. And even that small percentage should decline as organic gardening and agriculture continue to spread. Consider greenhouse gases--those carbon dioxides and methane that trap escaping heat and raise the earth’s temperature. Many experts say the accumulation of greenhouse gases in the upper atmosphere could lead‚ in two short generations‚ to a global warming that will have catastrophic effects--expanding deserts

I. Introduction The world’s current way to produce‚ convert and consume energy comes with a price. Development of sustainable energy technologies which can continue providing the society with energy-derived benefits without further environmental destructions is highly desired. A series of green energy solutions‚ such as solar‚ wind and biomass energy‚ are employed in the hope of preventing the impending global energy crisis (Wang‚ Chem and Huang 2010). Microbial Fuel Cells (MFCs) which capable

term ’fracking ’ in the news quite recently and perhaps wondered if the reality is as ugly as the word. There is an ever rising body of evidence‚ that there are inherent and unacceptably high environmental and health risks associated with coalbed methane and shale gas extraction - hydraulic fracturing (fracking). This is fast becoming a global issue happening in our own back gardens‚ it ’s contaminating our water supplies and tampering with mass food production industries. Something must clearly be

Shaniqua McIntosh April 15‚ 2013 Environmental Science Hydraulic Fracturing: The Problem Hydraulic Fracturing or fracking was first introduced in 1940s and has then been a key provider of natural gas and oil worldwide. Despite its expansion and customary use‚ fracking still poses many health and environmental concerns. During fracking‚ pressurized liquids are injected into drilled wells‚ which cause the surrounding rock to crack open allowing gas and oil flow through the fissures
