h poisonous gas that people were killed by the air they breathed in. what horrible scene!what we are suffering is only a small part of what the nature once suffered. if we don't take action to show respect to the environment, we will have to face an increasingly awful situation.
measures should be taken to protect the environment on which we are relying. first governments should forbid destroying vegetation, rivers and lakes, oceans, as and the atmosphere as well. second voices should be made to announce the public of the importance of protecting the environment. third enterprises should pay special attention to the effect they have on the environment and work out solutions for the problems.
only by changing the way we treat the environment can we get along well with it. only by saving the environment can we save ourselves.
