A lot of factors are responsible for the degeneration of environment, from deforestation to all types of pollution. Many animals, plants and even the microorganisms are under threat and may not exist in the near future, if proper steps are not taken to conserve and protect them. We are capable of bringing a change and we must do so before it is too late.
