problem-solution for global warming

Global warming simply means the heating of the earth's surface and the increase in temperature that leads to other problems in future. In the 21st century, it is considered a very dangerous threat as the glaciers are melting, sea levels are rising, droughts, floods, hurricanes and strange changes in climate are observed in different areas.( Business week.). It is a result of global warming that summers are longer than winters, and that the percentage of carbon dioxide in the atmosphere has increased. Moreover, it is also felt that the phenomenon will introduce new diseases, and hence is considered a global threat to health as well. For these reasons, global warming is one of the few issues that need the cooperation of governments around the world.

Commonly suggested solutions for the problem are alternative fuel sources, hybrid car technology and limiting emission of green house gases.(Global Warming skeptics). For reducing global warming many new technologies have been introduced that limit greenhouse gas production but at the same time do not threaten one's lifestyle and standard of living; an example is hybrid car technology and biofuels. Protecting oneself from the sun through sunscreens, hats and cotton clothes is also suggested to avoid allergies and other related problems. Many sceptics believe that the problem is not as dangerous as it is thought to be, but it is important for us to take steps in the right direction as there is evidence of the occurrence of global warming ( Eco bridge ). Running away from the problem and ignoring it will not help; many documentaries and articles provide information that proves that the globe is warming, so it is a useless debate.

According to me, an effective government is necessary to fight global warming; as common people, we cannot make policies that will be followed and a concerned government will make policies that will limit global warming and will also be able to implement those policies. Also, one should try to indulge in those activities that are enviro-friendly, should plant trees and ensure in small ways that water and energy are saved in day-to-day activities.

Cool cities:

Since the Industrial revolution, some problems have started such as rising in population, increase in energy consumption, and increase in carbon dioxide emission into the air and traffic delay.

Solving these problems in the coming days would save us. People should decrease the amount of the carbon dioxide emitted into the air by 50% to live within the capacity of a single earth. Japan GPA (Gross Domestic Product) has gone up in the past 30 years by 100% and energy efficiency has increased by 37% and 8% was decreased in oil consumption.
A Japanese organization made from group of companies called SDCJ has planned a project named cool city. Cool city is Model city with various technologies to cool the air and reduce the carbon dioxide emissions by 60%. This city uses hybrid cars, water taxi would be available and light mono rails as well. In addition, the city radius is estimated to be 1KM, which means that everything inside the city is easy to reach by walking. Cool city uses solar farm which are surrounded by many trees to prevent and hold sand storms.

My opinion:
In my opinion, cool city is a wonderful city because it is an environmentally city. In addition the city cares about our planet by many things like by tree planting ,waterways ,rooftop membranes. I hope there will be many cities like cool city.
