Cities and Nature With fast-paced urbanization and increasing use of land，more and more tall buildings come along nowadays.You can see heavy traffic everywhere and you can find that more and more green grass land are decreasing.The air pollution problem is coming to people with the development of the city.Even though our lives get more convinient，we are hurting the nature. In my opinion，I strongly think that humanity come from the nature，and also belong to the nature.So it's unreasonable for everyone to destroy the nature.The nature is like our own mother.However，who has the cold heart to hurt his own mother?Certainly not. You can imagine that one day the birds aren't singing in the sky，the flowers are dying，the water is too dirty to drink，the air is smelly，etc.The world won't be a happy heaven anymore，but a terrible hell world.At that time，will you miss the precious natural world? I recognize that it will be terrible to have no cities as well.But I think we can try our best to protect the nature when we are building a more modern city.The cities are home to us，and the nature is too. We are supposed to keep the rational attitude to cities and the nature.
