In the past, man don't have to think about the protection
of the environment. There were many people on the earth
and nature material resources seemed to be unlimited. Today
things are different. A world has become too crowded. We are
using our natural materials too quickly. In the same time,
we keep pollute our environment with dangerous chemicals.
Dustbins are filled with cans and bottle that once held
beer and coffee or Coca-Cola. Everywhere, people are always
throwing away wrappings from food to clothes and all kind
of unwanted things, some of them are difficult to get rid of. |
