=__﻿ What is Deforestation?__ = //Deforestation:// is the removal of a forest or stand of trees where the land is thereafter convereted to a nonforest area .Deforestation drives climate change, forest soils are moist, but without protection from a sun-blocking tree covering it they can quickly dry out. =__How Do Trees Help Us? __= Trees //help the water cycle// by returning water vapor back into the atmosphere.Trees also play a critical role in absorbing the greenhouse gases that fuel global warming. Fewer forests means larger amounts of greenhouse gases entering the atmosphere—and increased speed and severity of global warming.Without trees to fill these roles, many former forest lands can __quickly__ become barren desserts.

=**__What's SO Bad About Deforestation :__** = You may be thinking it a huge forest.... those trees can grow back....no big deal but the truth is that, removing trees //deprives// the forest of portions of its __canopy,__ which __blocks the sun’s rays during the day and holds in heat at night__. Deforestation has //many// negative effects on the environment. This disruption leads to more extreme temperatures that can be harmful to plants and animals. The most dramatic impact is a loss of habitat for millions of species. //70%// of Earth’s land animals and plants live in //forests//, and many cannot survive the deforestation that destroys their population. =﻿=

what is Ecological ? Deforestation results in declines in biodiversity.The removal or destruction of areas of forest cover has resulted in a degraded environment with reduced biodiversity. Forests support biodiversity, providing habitat for wildlife ; moreover, forests foster medicinal conservation. With forest biotopes being irreplaceable source of new drugs (such as taxol ), deforestation can destroy genetic variations (such as crop resistance) irretrievably.

=Hybrid Vehicels=

[|USE LESS GAS SAVE OUR RESOURCE AND MON EY]

==

These vehicals use less gas and more electrcity plus some hybrid vehicals have soler panels so they also use soler energy. We won't have to harm our air no more and we can breath cleaner now.
=﻿ ﻿How it works = ====﻿ ﻿ ﻿ ﻿A traditional hybrid vehicle, you have a complete electric car. Your car will also include an a electric motor to provide the power for your wheels, as well you well also have batteries to supply the motor with electricty. Seprated from all that you have a gasoline engine powering a generator. The engine is very small, maybe perphaps 10 to 20 horse power. And mainly designed to run at just one speed for max. effciency. The main purpose for a small engine is to provide enough power for the car at its crusing speed. At times of acceteration, the battery may provide extra power if necessary. At points of decelerating standing still, the batteries recharge. ====

This is with gasolined cars and other vehicels that put smog in the air. This will be are community if we all had gas effectancy hybrid and we can breath cleaner.

= ﻿Deos the solution of the Hybrid cars reallty help? = ==== ﻿Well this solution does relly work, while you may be driving you may be saving green. Not will you save money for your gas but you will help our world to have cleaner air. this will make a big difference in our community. ====
