Why is the world producing so much garbage? Garbage is an unavoidable result of consumption. And to 42 the
high standard of living that has been reached in many industrialized countries, we must continue to consume, as the
consumption keeps the wheel of industry turning. We use the rapidly disappearing natural resources of the earth to feed
the machines of industry, which 43 produce endless quantities of consumer goods. What we haven’t been able to
do, however, is to find a successful way to 44 all the by-products of industry and the products themselves when
they are used up, worn out, or 45 .
One of the biggest causes of the garbage problem is the world’s exploding population. More and more people means
more and more waste. Before the industrial revolution, when the world population was very small, the problem of
garbage did not exist. Whatever waste was produced then could be absorbed by the earth without 46 nature’s
balance, but nature can no longer cope with the amount of garbage that is currently being produced.
