26 world renown climatologist's studies show that by 2100, world sea level will rise more than 1m because of global warming. If world sea level rises by 30cm, many countries will be submerged. Global warming is an issue that needs to be addressed immediately. South Korea is one country that is a good model for energy conservation. Not only are Koreans conserving energy in the household, but the ROK military is also working hard to reduce carbon dioxide emission by conserving energy. I believe everyone in the world must participate in the conservation campaign for a better future.
