Task 7 : A Problem - solution report

Global warming: we are living now comfortable, but how can we deal with it if the global warming increases. Everyone can imagine that what could happen for our earth. It’s not just a problem for several years; it will be the problem for the earth’s life. Healthy earth means healthy life. Global warming is here now. Therefore the temperature keeps increasing every year. It is mainly caused by the increasing population which causes pollution to increase.
The problem is that global warming is already causing damage in many parts in the USA. In 2002, Colorado, Arizona and Oregon endured their worst wildfire seasons. In the same year, drought created dust storms and floods which caused hundreds of millions of dollars in damage. Snow accumulation has declined 60 percent and winter seasons have decreased in some areas. The impacts of global warming are not limited. In 2003, extreme heat waves caused more than 20,000 deaths in Europe and more than 1,500 deaths in India. Scientists think that these events are alarming signs that the area of the Arctic's perennial polar ice cap is melting at the rate of 9 percent per decade (www.nrdc.org).

Using clean technologies will reduce carbon pollution and other harmful pollutions that poison our atmosphere. Reducing global warming pollution helps to make our energy and transportation systems more efficient, protect our environment and wildlife, and improve our air quality and protect peoples’ health. Moreover, clean car technology can produce more efficient engines and better mileage. ( www.globalwarmingsolutions.org). There are some actions which should be done as a first step of protecting our earth from global warming:
• Increasing support for clean, renewable energy sources like wind and solar power, in order to decrease our demand on coal-fired power plants.
• Making our homes, businesses, and common products use less energy through energy efficiency improvements.
• Helping people to drive less by increasing support for our public transportation systems, or force them to use green cars.
• Making our cars and trucks go farther on a gallon of gas by increasing federal gas mileage standards. (www.pennenvironment.org).
• People have to reduce their carbon footprint also.
• Building cool cities makes the earth’s atmosphere healthier.
Global warming wouldn’t be reduced by one person’s participation. It has to have all of the people in the world trying to reduce their carbon footprint first and then we can reduce the incidence of global warming.

Task 6 : Cool City

Since the start of the industrial revolution the economic development has involved population pressure and CO2 emissions.
If we do not solve our problems we have to have another earth and that is impossible.
50% of CO2 emissions have to be decreased if we want to live within the capacity of a single earth.
In the last 30 years of GDP has gone up 100% in Japan, energy efficiency by 37% and oil consumption decreased by 8%.
90% of carbon dioxide into the air comes from building and transportation.
A Cool City is a place free of or with a very small proportion of carbon dioxide emissions. It is being built by SDCJ group from Japan.
Mono Rails, Solar Water taxis and Hybrid cars will be used in the cool city for transportation.
Comfortable space would be offered for walking inside the cool city.
The various zones in the city are Business, Commercial and Residential.
Techniques that will be used around the city are the jatropha forest will be surrounding the cool city. Also tree-planting, waterways and rooftop membranes.
The CO2 reductions expected are 50% for eco towers and 30% for eco residences.
Overall 60% of CO2 emissions have to be reduced.

Comment:
It is the best idea to live in a cool city, where everyone will live away from carbon emissions and noises in a quiet place with fresh air and with places to walk comfortably.
