Ecological problems

Everyday the planet has different problems; for example: quake, tsunami, volcano and floods. I think about why this happens with the planet! There are people that have a lot of opinions about the subject. Some say it is the global warming; others, that it is the effect of nature. This question is very complicated because it is necessary to study to understand these phenomena. Animals and people die in tragedies all the time. The government of each country has to solve this problem. Everybody can help to change this situation. For example, save water, eat little meat and recycle trash.
