We, human being has develop various technology to make our own lives more convenient and comfortable.  Then its pace of our progress  is so rapid that natural surroundings are changed dramatically.   Thinking about its effects on nature, I would like to conclude that our activities has make the earth a worse place to live. 

 

   Our activities to develop thechnologies which produce many convenient and beneficial things and enjoy its benefits have rather destroyed nature, necessities for our sound life.  For instance, in order to construct rail road, highway and so on, we have destroyed mountain and change sea line.  Harmful gasses from cars cause air pollution, which lead to acid rain and destruction of ozone layer.  Deforestation for producing wooden products or preparing the materials to construct building has destroyed ecosystem.  In this way, we have gained our convenient and comfortable life at the cost of nature.

 

  Although gaining lots of convenient goods, we have lost precious nature and better living condition which is provided by natural surroundings.  Plants produce oxygen, essential for our respiration and make air clear.  They also provide living place and food with other animals.  Therefore plants is essential for ecosystem, key of maintaining sound condition for all the animals, including human beings, on the earth to live.   Therefore destruction of nature means destruction of living condition.  In fact, as I said before, we have been suffered from the worsen living condition caused by destruction of environment.

 

 
  Despite our great effort to improve our living standard with the investing new convenient devices, we actually have lots of problems connected with our living condition namely environmental pollution.   Therefore, I think that the earth has become worse place as living space.
