In my opinion, the biggest problem that our environment suffers is the constant cutting down of trees. Trees are our oxygen, our lungs. Trees think and feel the same way we do and people cut them down. Its horrific. Cutting down trees impacts the purity of oxygen, therefor there are many imbalanced illnesses caused because of the free radicals and pollution. This not only impacts the environment, it holds a great effect on the health of humans and animals. Of course there are many other issues our beautiful world faces, but trees are what I hold close and dear to my heart.
