The two charts show that the increase in the US pollution has been accompanied by a corres
ponding decline in the number of wildlife species.
Far too many species have been lost already,
this poses a danger to the ecological balance.
As the human population expands, wild animals in mounting numbers are hunted for food,
or because they're thought to present a threat to men.
But studies show that one of the primary causes of the disappearance of wildlife
is pollution which is one of the consequences of population growth
and economic development.
this makes us wonder if men are able to share this planet in harmony
with other life forms.
In my opinion, this is imperative for us to make steps to reverse the disturbing trend
illustrated in the charts. One measure would be to forbidden the building of cities
in areas where wildlife is threatened with extinction. But more important,
man must learn to stop polluting the environment,or he himself will be extinct.
