Nature in danger of extinction[
We are destroying our forests faster than any other ecological zone in our planet. 
Forests cover only 6% of the Earth’s lands but they have between 50% to 90% of all plant and animal species from the planet. But unfortunately, humanity is destroying the forests faster and faster.
Many species of the rainforests (the ones that are located in a tropical area and which receive a lot of rain) benefit all of us. Many medicines (pharmaceuticals), for example, come from the rainforest. China, Brazil, Australia, and Mexico have a large number of species in extinction.
We are losing 50-100 species of plants and animals every day. Lost of species become extinct from natural processes. If we lose 50% of our planet’s species, it will take evolution 5-20 million years to replace them. Humans should help endangered species. We can work together to stop this destruction!
