1 . Universities are doing everything they can to become a green campus. But there are also items students can do to make your campus more eco-friendly.
Recycle everything, especially paper!
There is a large amount of paper a college student goes through every term.
Buy green.
Walk and bike to school.
Most campuses, especially those that are trying to become a more eco-friendly campus,have pretty good public transit (公共交通系统).
A water bottle can be refilled at any water fountain and can easily be drunk in class or while riding a bike. This will protect the environment by decreasing the amount of plastic waste on your campus.
Buy used clothing.
It is usually thought of as something to do to save money.
| A．Carry a water bottle. |
| B．It is also good for the environment! |
| C．Buy as many recycled products as possible. |
| D．Paper made of this kind of wood is much stronger. |
| E．On top of that, almost all universities are pedestrian (步行者) friendly. |
| F．It includes class notes, term papers, student newspapers and so on. |
| G．Universities call on all the students to learn to recycle all the waste paper. |
2 . Pollution’s great effects on the environment have become more obvious in recent years, leading to a movement to promote energy efficiency（效率）, and a reduction in air and water pollution. Most scientists agree that such changes are necessary to protect our environment from further harm.
Green buildings use less energy, water, create less waste, and are healthier to live, work, and go to school in than standard buildings. Builders of green buildings use techniques that use resources more efficiently during the entire building cycle — construction, restoration, operation, maintenance（维护）and removal — than those who construct more regular buildings.
The environmental benefits of green buildings include the protection of ecosystems and biodiversity, better air and water quality, less waste flowing into streams, and the protection of natural resources. Green buildings can also result in lower operating costs because they typically use less energy and fewer materials and improve indoor air quality, improving the health of people who live in such buildings.
The process of building green includes technical and artistic planning with nature protection in mind. Building designs often reflect the surrounding environment and natural resources and use renewable building materials such as bamboo and straw. In addition, recycled resources found locally are used for green buildings, reducing the cost and air pollution associated with transporting materials over long distances.
Careful site selection is important to reduce the human effect on the surrounding environment. For example, placing a structure in an area that allows it to take advantage of cool wind and sunlight can reduce energy use and expenses. More energy and expenses are needed for larger buildings as well, so it is important to build small ones.
The green roof is another feature of green buildings that reduce energy use and costs. These roofs are partly or completely covered with plants, which help to keep heating and cooling costs low, prevent water running off and deal with pollutants.
Other features of green buildings often include energy and water conservation, recycling, and waste reduction. In addition, renewable energy resources such as solar power, hydropower and wind power are used for heat and electricity, which greatly reduces costs and decreases the effect on the environment.

3 . Since the first Earth Day in 1970, Americans have gotten a lot “greener” toward the environment. “We didn’t know at that time there even was an environment, let alone that there was a problem with it,” says Bruce Anderson, president of Earth Day USA.
But what began as nothing important in public affairs has grown into a social movement .Business people, political leaders, university professors, and especially millions of grass-roots Americans are taking part in the movement. “The understanding has increased many， many times,” says Gaylord Nelson, the former governor from Wisconsin, who thought up the first. According to US government reports, emissions (排放)from cars and trucks have dropped from 10.3 million tons a year to 5.5 tons .The number of cities producing CO beyond the standard has been reduced from 40 to 9. Although serious problems still remain and need to be dealt with, the world is a safer and healthier place. A kind of “Green thinking” has become part of practices.
Great improvement has been achieved. In 1988 there were only 600 recycling programs; today in 1995 there are about 6,600. Advanced lights, motors, and building designs have helped save a lot of energy and therefore prevented pollution.
Twenty –five years ago, there were hardly any education programs for environment. Today, it’s hard to find a public school, university, or law school that does not have such a kind of program. “Until we do that, nothing else will change!” says Bruce Anderson.
