My symbol for deforestation.

Phew, finally I find the correct way to upload picture from illustrator.

Anyway, this is a symblo idicating the important of trees in reducing the effect of global warming.

Ok, now I'll describe it in more details:











1. The shape:
This symbol is made up of 3 main shapes.

• The tree means trees on this earth.

• The earth means Earth, nothing else.

• The outer circle means atmosphere.

2. The arrangement:

• The tree on the top of Earth means tree is actually very important to Earth. After all, it cover almost 30% of the land. (http://www.earth-policy.org/Indicators/Forest/2006.htm)

• The root of the tree covering part of the Earth mean trees are protecting the earth as its can reduce the rate of global warming, however, human's activities are causing the area of trees to be reduced. "Though extensive, the world’s forests have shrunk by some 40 percent since agriculture began 11,000 years ago. " (http://www.earth-policy.org/Indicators/Forest/2006.htm)

• The atmosphere means the present of trees can purify the air and reduce the effect of global warming.
  

3. The colors:

• Green tree = Trees as a part of nature which has its own duty on Earth.

• Red Earth = The growth of global warming on Earth is going fast, the Earth is hot.

• Orange land = The soil dries up and shows no sign of livings.

• Prediot atmosphere = The changes of climate due to global warming.
