Plant (Planet)earth seems to be being destroyed by human beings.

Nowadays the world has been ruined by people and is getting worse day to by day. Today there are 4 billions people lives all around the world moreover and birth rate is going up every year. Thus consuming (consumption) is increased (increasing.) by human Therefore everything is changing such as technology, car industry, food industry, (the car and food industries) , physics and so forth. So that; Humans have destroyed the world getting more goods and equipment.  (I don't know what you mean by this but I think you are trying to say Humans have destroyed the world by needing more goods and equipment.)
Chine (China) has (the) biggest population in the world (with)about 1.2 billion people levies in China. In addition to that it; China investors are building builds new house(s) and facility (facilities), but how they do (How do they do it?) They cut down some forest than then, build the houses in that place. If Now 20% of China’s people are getting lunch lung cancer because of the cutting of trees.
Second most important destroy is used gas or oil. (I once again don't know what you mean but I think you mean The second most important thing is using gas or oil) Today each per person has consumed consumes 124-litters of oil each year. Oil creates carbon dioxide and carbon dioxide effect (affects) (Effect- Result or a consequence. Affect: to cause a result or a consequence) to the vegetation and animal world very badly. For example last year in China “Balik” type of bird became extinct because of air population.
To sum it all up. All the governments all around the world should stops the annihilation very soon because if they don’t, the next generation might have problems such as disease, cancer, and disability etc.
