     In the decade of the 1970s, the United Nations organized several important meetings on the human
environment to study a very serious problem.We humans are destroying the world around us.We are
using up all of our natural resources.We must learn to conserve (保护) them, or life will be very bad for
our children and grandchildren.
     There are several major aspects of this problem.
     1.Population.Most problems of the environment come from population growth.In 1700 there were
625 million people in the world；in 1900 there were 1.6 billion；in 1950,2.5 billion；and in 1980,4.4
billion.In the year 2200 there will be 6.3 billion.More people need more water, more food, more wood,
and more petroleum.
     2.Distribution(分布).Scientists say there is enough water in the world for everyone, but some
countries have a lot of water and  some have only a little.Some areas get all their rain during one season.
The rest of the year is dry.
      3.Petroleum.We are using up the world's petroleum.We use it in our cars and to heat our buildings in
winter, Farmers use petrochemicals to make the soil rich.They use them to kill insects on those plants.
These chemicals go into rivers and lakes and kill the fish there.Thousands of people also die from these
chemicals every year.Chemicals also go into the air and pollute it.Winds carry this polluted air to other
countries and other continents.
     4.Poverty.Poor farmers use the same land over and over.The land needs a rest so that it will be better
next year.However, the farmer must have food every year.Poor people cut down trees for firewood.In
some areas when the trees are gone, the land becomes desert.However, people need wood to cook their
food now.Poor people cannot save the environment for the future.
     We now have the information and the ability to solve these problems.However, this is not a problem
for one country or one area of the world.It is a problem for all humans.The people and the nation of the
world must work together to conserve the world's resources.No one controls the future, but we all help
make it.
