The Threats to the Environment

Green earth, clean earth
23 April 2010
Our land is in trouble it needs your help,
So are the oceans, the coral, the kelp.
There must be a way for all to unite,
To stop the earth from a disastrous fright.
We can't leave this world a barren waste land,
But luscious and fertile, as many creatures as there are sand.
We're destroying our jungles, our forests our beaches,
Taking away what is the earth's like billions of leeches. a
Few natural habitats are left on this globe,
All are scattered like the rays of strobe.
We welcome you to an endangered land,
To show you how animals dwindle like an hour glass's sand.
Only you can help save earth,
And hopefully, with care give it a rebirth.
Pollution, deforestation and extinction of various species are some of the serious problems endangering earth. Although its late but some efforts can lessen the problem if not totally eradicate it, as every bit counts.
Of all these, pollution needs our utmost attention. Farmers should use more of biodegradable waste as fertilizers instead of chemicals. The garbage dumps need to be cleared to prevent soil contamination thereby yielding better crops. Everybody has the right to live. To make this planet a better place for animals enough national parks should be built, where they can survive in peace. Steps should also be taken towards afforestation. We should get into the habit of using recycled paper and eco-friendly objects and mustn't waste paper. We have created this problem and now it's up to us find a solution to it. Each one of us can make some contribution to save our Planet Earth from the apocalyptic global warming. Man needs to think reasonably before using the available resources just to flaunt his wealth. Instead of fast depleting petroleum, technology should focus on ecofriendly fuel so that vehicles can use a freely available source like solar energy. More trees should be planted so that the balance of nature is not disturbed.
Let's wake up before it's too late.

“Clean Energy/Green Earth”
Clean Energy research has seen large increase in politics of the modern day world. The demand for safer and renewable energy sources has become a larger issue because of the now known effects it has on the environment. Some much so that we have seen it play a huge role even in the political circle and is a major topic of debate. Renewable Energy has been increasing with advancements in technology and the overbearing concern of using alternative energy as fossil fuels. Plus Global Warming has made the paybacks of Renewable Energy seem more attractive with each passing year. There are many types of Renewable Energy types, the three major forms of renewable energy are solar energy, wind energy and biomass energy (Bio Fuels). Each type of renewable energy has advantages and disadvantages which are specific to that type of alternative energy. For example Solar and Wind are intermittent in nature while Geothermal Energy has no such problems however Geothermal Energy suffers from a lack of good sites and takes a long time to become installed. Plus cost too is a major factor.
Solar Power has been the fastest rising energy cause in the last few decades, showing a increasing annual development. More and more solar stations can be seen built all over the world by private practices, higher education institutes and governments’ alike. In 2010 alone, solar energy demand grew by almost 150% surprising the most optimistic projections as costs kept on declining for this renewable energy cradle. While Solar Power endures to be one of the most costly forms of energy, it is also the energy source where the costs are declining speedily. With solar costs going down each year over the next few years, expect solar energy to grow at a faster rate in the future.
The next major renewable resource is wind power. Wind Power is the next biggest source of renewable energy after Nuclear and Hydro Energy (if you consider Nuclear/Hydro to be renewable energy that is)....
