Why cutting trees is bad?

Large scale tree cutting can lead to deforestation, a transformation of an area from forest to terrain with little vegetation. Plants create oxygen and absorb greenhouse gases. The destruction of trees may, therefore, encourage global warming. Changing temperatures can alter which organisms can survive in an ecosystem.
