my BIGGEST issue with this planet

In this world i have struggle to comprehend why people are failing to take care of our mother planet earth. The destruction of nature deeply saddens me. As a person who lives very close and who's life style is heavily involved in nature it makes me sick to see litter on the sides of the road, bottles floating down the creeks and river and pollution killing the animals in the ponds. in the Susqahana river, the fish I catch are unnaturally discolored and pale. its very upsettin to see the way he world treats its home.
