Human's instinct

     Essentially, human have instinct which they want to develop more high-tech. They make more convenient machine like airconditioner, car and KTX. After making that, the one who invented the technique want to sell them with taking some amount of money. Company will buy that, if they think that the technique is lucrative, although the company know the machine being made by using the technique make pollutants. They sell products and make much money.  After then, some Environment Agency and people become to recognize flaw of machine in terms of environment. So they do strike and persuade people not to use and buy the products any more. However people who experience convenience of them don't want to lose them.
     So although we know fully pollutants which is being maded by them, we can not practice easily some strategies for nature. If we didn't know that and had not taste  the sweet of them, we would not have any difficulties everyday when we live with not having the products. We are also human and know very well human's instinct, so we can not just blame for making some new products which have bad effects on nature.  We can not determine easily what is right or not.  So, what is the best choice when we make some new products and propagate them?
     As you know, Emission Trading is. Blocking up developing high-tech society is impossible, we can make exact limit we can pollute nature in proportional to nation size.  Through this regulation, we can delay environmental pollution somewhat.
     Always, compromise shoul be made between environmentalist and people who protect development. All of them want to make better life, so they insist their thinking. Don't ignore and listen carefully each other's saying.
     Maybe it would be my megalomania. We can make more eco-friendly tech in the future.  So we can live in more high life style and protect nature.
