Cool City.

According to Cool City video, the economy these days is different from the last 20 years; everything is changed; it has developed in an enormous way and made some negative effects on the environment such as pollution, car traffic, an increase in the amount of carbon dioxide being emitted into the air, and an increase of population. However if these problems are not solved on time, we will have to find and replace our earth with another planet. As we can see from the graph that shows on Cool City video, 90% of carbon dioxide is coming from buildings and transport. The SDCJ is several companies that came together and they are trying to make a project, an environmentally friendly and green city which is called Cool City. Moreover transportation will be different from a normal city; there will be light rail transit, solar water ship, and hybrid cars. Cool City will be using natural energy like the sun’s energy, wind, and water. But nothing is impossible with technology. In my opinion, it will take time to build Cool City with lots of technology, and maybe a new source of energy will be discovered while they are building Cool City, and it will cost billions of dollars and still the carbon dioxide won’t fade away; it will just reduce it, so no point in building the City.
