Deforestation is when a large portion of a forest is cut down. This leads to many local ecological problems, and to global ones. This not only includes oxygen content, but also a reduction in the Earth’s ability to filter carbon out of the atmosphere and it also significantly alters the water table in the region, making long term farming difficult.
