This world always exists controversial issues, and the environment is not except  .In my opinion , Environment pollution and warming global is an important issue that needs the world’s immediate attention.  The first, environment pollution  have brought negative effects to humans.  environment pollution occurs in many developing countries, including Vietnam . Quality of water is reduced, people have to deal with dangerous diseases caused by oil spills, and other waste. You can see waste every where. You can  smell  garbage from the black river surrounded city. You  can’t drink well-water directly. .. ,So what is the cause of the problem,The main reason is human beings . There are so much industrial factories in city,  there are many vehicles in streets, them released smoke into the  atmosphere. And more, forest has being destroy, the atmosphere more and  more polluted. especially ,the world's climate is changing, it is becoming hotter and hotter, some plants and animals will become extinct.If we want to have a good environment we must think and act responsibly. Governments must have laws to protect the environment,can put more  trash in  public areas.However, educating people and raising their awareness in protecting nature is still the most important.
