Global Warming

Nowadays, global warming is a rising serious problem all over the world. Therefore I think we should try to prevent this together.
First, in personally we ought not to try to release Freon gas. For that, we can prevent air-conditioner and dryer from using. It is well known that air-conditioner is a major criminal of Freon gas. Also we can use alternative energy. For doing that, we need to resign excess expence. Lastly, we can walk in near distance instead of taking traffic.
Secondly, for preventing global warming we should do not only personal efforts but also national efforts. There are lots of things in national efforts. We can make appropriate alternative energy and make it activate. It must be spent lots of time but I believe it is a valuable work. Also we can make nations recognize the reason why we should prevent global warming by campaign and so on. For solving this , awardness is very neccessary thing and national has responsibility to let everyone know importance of that. Also we can make recyle activate.
In conclusion, we can do lots of activities to prevent it. We can make an effort by both personal and national. In personal effort, we should try to use alternative energy ,walk instead of taking traffic and try not to use air-conditionaer and dryer. In national effort, we can make appropriate alternative energy and make it activate, nationas recognize the reason why we should prevent globlal warming by campaign and so on to people and make recycle activate. These days global warming is a acute issue all over the world and we should prevent it not only for us but also for our children.
