2 . The discussion on renewable energy has been going on for at least a decade and people have relied on fossil fuels almost entirely for more than a century. However, the situation when fossil fuels were the most efficient and the cheapest source of energy has been left far in the past. Many countries such as Germany and Sweden have already made significant efforts to fix this situation, employing numerous power plants working on the renewable resources of energy. The most effective among these resources is geothermal (地热的) energy.
Geothermal energy does not depend on the world’s economic and political situation as strongly as fossil fuels do. Besides, extracting (提炼) fossil fuels adds to the price of energy produced from them. Therefore, geothermal energy is much cheaper than traditional ones, saving up to 80% of the costs over fossil fuels.
Being a renewable resource, geothermal energy produces less waste and pollution than traditional energy sources. In geothermal systems, carbon dioxide makes up about 10% of air produced. Overall, in order to produce the electricity that can be used for one hour, the geothermal systems produce 0.1 pound of carbon dioxide and other harmful gases. For a comparison, a power plant producing from gas produces up to 2 pounds of carbon dioxide into the atmosphere, and those power plants that work on coal (煤) produce an astonishing 3.6 pounds of greenhouse gases.
Low costs is another reason why using geothermal power plants should be the first choice for many countries. Geothermal heat systems require 25% to 50% less energy for work compared with the traditional systems for heating or cooling. Besides, geothermal equipment is less big: due to the very nature of geothermal energy, geothermal power plants have only a few moving parts, all of which can be easily sheltered inside a relatively small building. What’s more, the life span of geothermal equipment is rather long. All these make geothermal power stations easy to build and keep.

4 . Four Wild Animal Species Were Endangered
Maybe you can still see them at the zoo. But that doesn’t mean they’re doing alright in the wild.
Tigers
All six tiger species are endangered, with Sumatran tigers and South Chin tigers at a seriously endangered status. The main reasons for their population decline are illegal hunting and destroyed habitats(栖息地), as humans clear forests to gather timber(木材)and build roadways. Only about 3890 tigers presently live in the wild.
Ground squirrels
That’s right, even squirrels are endangered, specifically the San Joaquin ground squirrel. Native to California, USA, these guys have been disappearing since 1979 on account of the construction and human developments going through their habitat. Their total population is unknown , but it could be anywhere between 124000 and 413000.
Giraffes
The International Union for the Conservation of Nature recently put giraffes at a vulnerable status, the level just before endangered. The giraffe population has declined 40 percent in the last 30 years, primarily due to loss of habitat and illegal hunting. Some giraffes are killed just for their tails, which are considered status symbols in Africa.
Asian elephants
The main threat to Asian elephants, one of the most intelligent animals, is their shrinking habitat. As the human population grows, people invade their land to build roads and railway tracks. Elephants in Myanmar are at an especially high risk for being captured and traded or used illegally in the tourist industry. Fewer than 50000 are left on the entire continent.

Dear Sir, I am a student from the near school. Here I want to report the environmental situation for you. There used to many green trees and all kind of flowers in our school all the year round. The school looks like a beautiful garden and we had a clean studying environment. And everything has changed since your chemical factory was built a year before. Every day it produces lots of waste water and harm gases. The terrible pollution has been done great harm to our health. We all expect you factory can take measures to stop the pollution soon.
