Cool Cities

The world is going downhill with the increase of emissions every year which is the main reason for global warming and climate change. Since the start of the industrial revolution, there have been some problems related to economic development like the rise in populations, the increase in energy consumption and the carbon dioxide which is emitted into the air. If these problems continue we will need more than one planet to live on which is impossible. People have to decrease the amount of carbon dioxide emitted into the air by a lot so that we wouldn’t need to find another place to live on.

In Japan during the last 30 years the GDP has gone up 100% while energy efficiency has increased 37% and oil consumption has decreased 8%. About 90% of carbon dioxide emitted into the air comes from buildings and transportation. Cool City was being built by SDCJ which is from Japan. There are three types of transportation that will be used in the Cool City which are hybrid cars, water taxis and light rail. There are various zones which will be in the city like business and residential. There are some techniques that will reduce heat by water, trees and roof membranes. 60% is the overall percentage of reduction of CO2 emissions claimed in the video.

With the development of the world and the increasing of industrial activities, the world is polluted day by day because of these activities. The video says this problem is serious and we should stop the bad activities that pollute the earth. If we do not stop polluting the earth our life will become worse. The humans will suffer a lot if this problem persists and their life will be endangered. We do not have any options and we should choose the green option or we will have no clean environment to live in.
