Deforestation is cut down of trees on a massive scale. This is very bed for the planet, because could change the climate, the animals lose their habitat and loss of biodiversity, causes damage on the agriculture and soil erosion destruction.

Some species don't be able to climate change and go away and this causes loss of biodiversity.
