Discussions Discussion Deforestation SOS
Camila P- USA, Nov. 12, 2012

Hello everyone,
Rainforests are home to 50% of all species on earth in only 2% of all earth’s land. Therefore, the earths oxygen production does depend on the rainforest plant life quite a bit because of the photosynthesis process. As you many know, photosynthesis is the process where plants use CO2 and sunlight to gain energy, and releases oxygen as a waste product into the environment. Because of increased deforestation, carbon dioxide levels are steadily increasing.
Carbon dioxide is a gas that absorbs the sun’s UV rays, and ruins the ozone layer that protects the earth from these harmful rays. Deforestation causes a weaker ozone layer, further leading to global warming. Not only does deforestation interfere with the earth’s way of removing carbon dioxide, but it also adds carbon dioxide emission because the trees are usually burned after being cut down. When deforestation is paired with other carbon emitting activities such as aviation, automobiles, telephones, or heavy use of electronics, global warming can become even worse condition than it already is.

The Black Rhino is now officially extinct. It has not been seen in West Africa since 2006.


The plight of the rhino is a stark reminder of what scientists call the next great extinction after the dinosaurs 65 million years ago.

    Very sad that we humans could not figure out how to not exterminate such a majestic animal from the face of the earth. Feels very strange.

    This seems almost like criminally negligent behavior on behalf of the entire human race.
