What causes the global warming ?

In nowadays, we profit the advantage of the fast development of science and the high technology. The quality of our live has been way more better than one hundred years ago. But while we benefit from the advantage of the science development, we always forgot the consequences.

If you have ever paid attention, you would have realized that deforestations has been going on from the 90s until now. Millions of trees were cut down and rainforests were destroyed. 39 million areas of rainforests were destroyed in 2017 for the need of humans such as paper, palm oil, etc. 50% of plant and animal species on earth live in rainforests. 40% of the air we breath are produced by rainforests. Many animals have been loosing their home because of the deforestation, like the orangutans, the squirrels, the coons, and that’s not the only aftereffect of the exploration.

The cause of the global warning is the overexploiting in the 90’s. In the pass 30 years, almost no one realized the serious consequents that will hit the world if we continue to produce pollutions. It’s now that we realize them. People have started to pay attention about the global warming. Did you see the crowd at the global warning manifestation in Montreal last year? Have you noticed the #globalwarningisreal tag on instagram? That people start using recyclable bags and metal water bottles instead of plastic bags and plastic bottles? But it’s somehow already too late. Many animals have become endangered species because of the global warming – for example, the polar bear.
