81. As we all know that since man appeared on the earth, man's survival has been heavily relied on nature,and man cannot live without nature. Almost everything we use in our everyday life comes from nature,ranging from the food we eat, the water we drink, to the wood which is turned into furniture.
With the development of technology and population growth, the amount and range of materials used has increased at a alarming rate.
However, natural resources are not inexhaustible.Some reserves are already on the brink of exhaustion and there is no hope of replacing them.The widespread water shortage is an example in point. If man continued to squander natural resources with no thought for the future, the later generations would be in danger. It is up to us to take effective measures before the situation become worse. We must take positive steps right now to put an end the plundering of the earth's natural resources.
