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．
According to the passage, our world is being destroyed mainly because ______．
A．pollution is getting worse and worse
B．population are increasing greatly
C．we humans are using up all of our natural resources
D．distribution is not reasonable．
Good distribution means ________．
A．having things in the right place at the right time．
B．cutting down forests and selling them to other countries．
C．building water systems to carry water to farms．
D．conserving our natural resources
The best title of the passage should be ________
A．The World Being Destroyed
B．A Serious Problem We Should Pay Attention to
C．Aspects That Destroyed Our World
D．Conserving the World’s Natural Resources

Man-made Causes
Man-made causes probably do the most damage. There are many man-made causes. 21 is one of the biggest man-made problems. Pollution 22 in many shapes and sizes. Burning fossil fuels is one thing that causes pollution. Fossil(化石) fuels(燃料)are fuels made of organic matter such as coal, or oil. when fossil fuels are burned they 23 a green house gas called CO2. Also mining coal and oil allows methane to escape. How does it escape? Methane(甲烷)is 24 in the ground. 25 coal or oil is mined you have to dig up the earth a little. When you dig up the fossil fuels you dig up the methane as well.
Another major man-made 26 of Global Warming is population. More people 27 more food, and more methods of transportation, right? That means more methane because 28 will be more burning of fossil fuels, 29 more agriculture. Now you’re probably thinking, “Wait a minute, you said agriculture is going to be damaged by Global Warming, but 30 you’re saying agriculture is going to help cause Global Warming?” Well, have you 31 been in a barn filled with animals and you smell something 32 ? You re 33 methane. Another source of methane is manure. Because more food is needed we have to raise food. Animals like cows are a source of food which means more manure and methane. Another problem 34 the increasing population is 35 . More people means more cars, and more cares means more pollution. Also, many people have more than one car.
Since CO2 contributes to global warming, the increase in population makes the problem worse because we breathe out CO2. 36 , the trees that change our CO2 to oxygen are being demolished because we’re using the land that we cut the trees down from as property 37 our homes and buildings. We are not replacing the trees(an important part of our ecosystem), so we are 38 taking 39 of our natural resources and giving nothing back in 40 .
