In recent years the problem of environmental pollution has become a serious problem in big cities in our country. So, what are reasons and possible measures for this problem? Nowadays, we are living in a city with high population density, so domestic waste is the first reason. Then many people's social consciousness is not high. In several areas, they throw rubbish on streets, canals and rivers. It is easy for us to see rubbish of all kinds floating on the water. Moreover, uncultured people even pee in the public place. Now, let's come to other reasons. Our city is overloaded with vehicles that expel a lot of smoke and dust. This contributes to the heat of the air, and causes pollution.  Besides that, in several places, trees have been cut down to have room for buildings, hotels, or supermarkets. This makes the atmosphere in our city mug and stuffy. In addition, many plants and factories send out waste into canals or poisonous gas into the air. Last but not least, the drainage system in our city is very old and downgrade, so it is always flooded whenever it rains.
