Climate change problems and solution

The procedure of the global warming is very harmful for the human beings, because the problem of could destroy the earth, and make it warmer. Unfortunately, it was only man to blame for this phenomenon because he increases the effectiveness of climate change by increasing the harmful gases in the atmosphere (http://en.wikipedia.org/Wiki/Global_warming,p.1,line 1 and 2).

There are many influences and factors related to climate change, e.g. there are people driving cars which are the most important producers of the gases; and also another problem is that global warming has reached a ceiling and cannot increase the rate as it is and this is the turning point that we must identify and then overcome, and solve this issue. (http://boards.virginmedia.com/digital/soundbites/carbontargets.html? Page=12. P.4.).

Although there are many problems caused by the global warming, we can stop this problem. Nowadays many people are concerned about this issue and are trying to live in a healthy environment. The people who are environmental friendly like to use many things to reduce the carbon footprint; first in their life they use less carbon footprint than the others. Secondly, one more thing that you can do to avoid the global warming is using electric cars which do not emit Co2. (http://www.treehugger.com/files/2008/07/17-electric-cars-overview-2005-to-2008 second paragraph.).php) rather than the old ones which increase the carbon emissions. Secondly, why don’t we build more and more of the cool cities? These have a lack of carbon footprint and emissions, compared with the normal cities: the ordinary one uses carbon more than the cool cities by nearly 35%; this percentage can kill a lot of animals, plants, and humans. Last step; let us advertise in the media about the risk of cutting down the trees, because the trees make a balance between oxygen and Co2.

The global warming isn’t simple and most people aren’t concerned about it . I think one way to help people develop the environment is by the campaigns that tell the people to worry more about cutting trees.

cool cities

All over the world, communities are taking action to help solve global warming. From hybrid vehicles, green buildings, and homes powered with renewable energy to what we eat, all lead to a healthy environment which has fewer carbon emissions. We need to reduce CO2 emissions by 50%.

Japan is a developed and competitive country of the industrialized and developed world. In Japan, over the last 30 years GDP has gone up 100% but energy efficiency has increased 37%, oil consumption has fallen 8%. 90% of carbon emissions come from buildings and transportation. The cool city is the city which is very friendly to the environment with fewer carbon emissions. It is being built by SDCJ, a group of Japanese companies.

The environmental cities are using three types of transportation which are hybrid cars, water taxis, and light rail transit.

There are 3 main zones in cool cities, which are: Business, Cultural, and Residential.

It uses techniques which help to reduce the heating e.g. tree-planting, waterways, and rooftop membranes.

The percentage of expected CO2 reductions for eco-towers is 50% & for eco-residences 30%.

Overall reduction of CO2 emissions is expected to be 60%.

How practical/ realistic is the video?

It is a very good and successful project, because it is all concerned about how to keep the environment protected , but it will need a lot of planning, organizing, and controlling, and all of it will take a long time to be prepared well. In addition it will lead to changes in the life styles, and in the transportation system
