global warming

At now, Human kind are warned about global warming's result. as growing concerns about global warming, many of nations in the world have started to preserve nature from menace of global warming. however, these efforts don't seem to be realized effectively in our life. so, I'll introduce diverse efforts to prevent global warming which may be more practical.
First, we must know personal effort affects global warming pace mostly. the best method is that people recognize about nature in danger of our own accord. if all the people acknowledge nature in serious danger, not only global warming but also other environmental problems are going to easy to be solved. also, people should try to reduce CO2 which is the key factor in global warming by using air conditioning system less than ever. in similar, people can reduce CO2 by using public transpartation such as bus and train. in recent days, using by bicycle has also spotlight in eco-important-era.
secondly, the system of national effort about global warming must go with personal effort of citizen. nation can hold many campaigns about nature in danger to awake people. and to take substantial impact nations need to encourage people to use environmentally friendly products. on the other hand, nations of the world must pay attention to develop new energy which generate less carbon dioxide. this will be nearly ultimate means to go to the green world.
In conclusion, personal efforts wil go under the basic part of preventing global warming and then, national efforts follow the result of personal efforts by reforming fundamental problems of it. personal efforts and national efforts are ought to go along same context. and then, these efforts get synergy effect.

Summary
recently, a number of people have joined environmental-friendly construction. environmental buildings called 'green building' have some features. first, they have big windows for using less electricity and more natural light. second, they have rooftop garden which help control amount of sun's heat every season. third, for saving water, they have a special drainage system to collect rainwater and store it. and we can build with green materials such as bamboo, newspaper and plastic milk containers. from now on, we must construct buildings with green features and surely, the buildings we live are getting healthier and greater.

Comment
It is good for us to recommend many examples about green buildings. but, I think it is so limited to be realized in case of buildings with newspaper and plastic containers. It will be somewhat deficient in structure and safety. so, people may not go that buildings. and drainage system to collect rainwater must be reformed practically. it may involve purifying equipment to use water in common life because of air pollution. also, rooftop garden's maintenance expense may be so high-priced because it is located on rooftop so it is complicated to manage. I think it is difficult to settle green technology in space we live due to its expense and maintenance
