In the decade(十年)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 must learn to protect them, or life will be very bad for our children and grandchildren.
There are several major aspects to this problem.
Population
Most problems of the environment come from population growth.In 1700 there were 635 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 2010 there will be 7.3 billion.More people need more water, more food, more wood, and more petroleum.
Distribution
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 rain during one season.The rest of the year is dry.
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 countries.
Poverty
Poor farmers use the same land over and over.The land needs a rest so 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 huge 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 protect the world’s resources.No one controls the future, but we all help make it.

London, Dec.17 (Xinhua) “Drivers on London Underground trains have started reading out sayings from great thinkers like Mahatma Gandhi , Frindrich Engels, and Albert Einstein in a bid to cheer up passengers ,” officials said.

Amsterdam, Nov.30 (Xinhua) A few cups of coffee a day may not only help to put off the disease—dementia(痴呆) but also can treat it, according to Dr. Arendash, who led the research. After giving mice with memory damage water containing caffeine, he found the mice developed better memories and quick thinking. The reason is that caffeine is a safe drug for most people. It easily enters the brain and directly affects the disease process.
