deforestation part 2

Deforestation is a substantial contributor to global warming,and although 70% of the oxygen we breathe comes from the photosynthesis of marine green algae and cyanobacteria, the mass destroying of the worlds rain forests is not beneficial to our environment. In addition, the incineration and burning of forest plants in order to clear land releases tonnes of CO2 which increases the impact of global warming. Global warming also affects the habitat losses of animals.

For example, the polar ice caps are melting at a higher rate due global warming that is further enhanced by deforestation as there is lesser trees to absorb carbon dioxide. Animals who live in the North and South Poles will be affected. Polar bears may die due to the hot weather that is caused by global warming or even get drowned as the ice keeps melting, increasing the overall sea level.
