In a way, all of us are on a spaceship, the planet Earth. We move around the sun at 18 miles per second and never stop. On our spaceship we have five billion people and a limited supply of air, water, and land. These supplies have to be used carefully because we can’t buy new air, water, or land from anywhere else.
The environment on our planet is a closed system Nothing new is ever added. Nature recycles its resources. Water, for example, evaporates and rises as visible drops to form clouds. This same water returns to the earth as rain or snow. The rain that falls today is actually the same water that fell on the land 70 million years ago.
Today, the Earth is in trouble. Factories pour dirty water into our rivers. Many fish die and the water become unhealthy for people to drink. Cars and factories put poisons into the air and cause plants, animals and people to get sick. People throw bottles and paper out of their car windows, and the roadside becomes covered with all sorts of wastes. Over the years, people have changed the environment, and we have pollution.
To continue to survive, we must learn how to use the Earth’s resources wisely. We have to change our habits and stop dumping such enormous amounts of industrial waste into the water and air. We must cooperate with nature and learn better ways to use, not to abuse, our environment.
选项
A、Because the Earth is heavily polluted.
B、Because nature cannot recycle its resources.
C、Because there are more and more people living on the Earth.
D、Because no more new resources can be added.
答案
D
解析
短文中有这样一句话“The environment on our planet is a closed system:Nothing new is ever added.”可以了解到,D项“没有新的再可增加的资源”是正确的选项。
