Every year on June fifth many countries celebrate World Environment Day. The United Nations established this special day in nineteen seventy-two to get people to think about taking care of the planet. Faith Lapidus tells us more.
“Public events for World Environment Day are taking place from June first through June fifth. The events and conferences help teach world leaders and citizens how to protect the environment.
“Every year World Environment Day is celebrated in a different city. This year it is being held in San Francisco, California. This is the first time since the beginning of World Environment Day that the conference is being held in the United States. The main message of World
Environment Day this year is ‘Plan for the Planet’. The events and conferences will show how to have ‘Green Cities’. This means that people will talk about ways that cities can have healthy environments.
“Most people in the world live in cities. This makes them especially important areas of
environmental concern. Cities use more than seventy-five percent of the world's natural resources such as water and gasoline. World Environment Day will center on how people in cities can work together to help save the planet.
“San Francisco is holding public talks to discuss pollution reduction, clean energy sources and the importance of healthy parks and gardens. Special experts are among the speakers. For example, former vice-president Al Gore will talk about climate change. There also are fun events such as music concerts, movies, art shows, parades, bicycle rides and tree plantings. Local farmers and restaurant owners will serve food that has been naturally grown.
“The Mayor of San Francisco, Gavin Newsom, invited city leaders from all over the world to attend this conference and share ideas. Representatives from many environmental organizations also are attending. The United Nations hopes to create an international agreement that countries and citizens will follow to help improve the Earth's environment.”

The sense of sound is one of our most important means of knowing what is going on around us. Sound has a wasted product, too, in the form of noise. Noise has been called unwanted sound. Noise is growing and it may get much worse before it gets and better.
Scientists, for several years, have been studying how noise affects people and animals. They are surprised by what they have learned. Peace and quiet are becoming harder to find. Noise pollution—the crashing, squeaking, banging, hammering of people—is no joke. It is a threat that should be looked at carefully. Sound is measured in units called “decibels”. At a level of 140 decibels people feel pain in their ears.
Automobiles, trucks, buses, motorcycles, airplanes, boats, factories, bands—all these things make noise. They bother not only our ears, but our minds and bodies as well. There is a saying about it being so noisy that you can’t hear yourself think. Doctors who study noise believe that we must sometimes hear ourselves think. If we don’t we may have headaches, other aches and pains, or even worse mental problems. Noise adds more tension to society that already faces enough stress. But noise is not a new problem. In ancient Rome, people complained so much about noise that the government stopped chariots from moving through the streets at night!
Noise can be separated into a few general groups. The following examples are taken from hearings before the US Senate Subcommittee on Air and Water Pollution in 1970.
Occupational noise—Factory workers who always hear noise have poorer hearing than other groups.
Aircraft noise—Around airports or on air routes the noise of airplanes taking off and landing causes the greatest complaints.
Traffic noise—Away from the noise of planes, traffic sounds break in on our peace and quiet. Trucks and motorcycles cause the most problems.

【原文】
We usually think of pollution as a harmful waste substance that threatens the air and water. But some people have become concerned about another kind of pollution. It can be everywhere, depending on the time of day. And it was not thought of as a substance. It is light.
