A famous environmental activist should be honored

People's activities have caused serious damage to the environment such as air pollution, water pollution, and global warming. There is a very famous environmental activists named Zhang Yang in my country who is not content with passive empathy for environmental problems and inspired by proactive opportunities to bring about his vision of a better world. Therefore, we should build a statue to honor his great contribution to our planet.  

#Note that I changed all the periods (.) and commas (,) in your essay by removing the empty space in front of them.

#I like your phrase "passive empathy for the environment." That is truly the problem with civilization today.

First of all, he always often imparts to us that one of the most serious effect of human activity on the environment is water pollution.

#You cannot do something "always" and "often". You either do it "always" or you do it "often".

#One "imparts" knowledge. A person cannot impart another person. Instead, a person can impart (knowledge) to another person.

In one of his lecture he told us that dumping the water from human activity into the river and stream is very popular in today's China. The waster will make the water downstream become undrinkable and unusable for agriculture. The main source of water pollution is factory waster, oil, and gas runoff from the highway. He also investigated the pollution situation of many factories under the menace of their workers.

Secondly, in addition to water pollution, he also concerned with the problem of global warming. He found that average temperature of our country constantly rise due to the rise of the green house in the atmosphere . He often publicizes in mass media that if people continue to rise raise the amount of green-house gas in the atmosphere, the temperature of the planet will continue to rise, and melt the polar ice caps. Eventually major cities like Hong Kong and Guang Zhou will be totally destroyed. He often advises the government to control the burning of fossil fuel so that to decrease the amount of the green-house gases.
#"Raise" and "Rise" are common words for English speakers to misuse. 

"Raise" is used when the actor is causing another object to go higher. ("Raise a window")

"Rise" is used when an object is causing itself to go higher. ("Rise from bed.")

In your sentence, you have a proper use of both words. Humans are 'raising' the temperature, so we can say that the temperature is 'rising.'

Finally, he claims that air pollution in our country will impact our health most in many occasions. He always blames the modern transportation, such as modern gas-powered automobile as well as the electrical generators that burn fossil fuel and pour chemical waster for polluting the air. Through his investigation  he found that air-borne pollution will falls back into the earth in the form of acid rain, destroying the plant life and human buildings .


People seldom care about things that don't benefit them directly. Zhang is famed for revealing that it is time to realize the hazard of the serious environment pollution and take action to provent further disaster. Our country needs a celebrity like him to help publicize the protection of our environment.  Building a statue can would not only honor him, it can would also remind us to protect our planet.
