HOMEWORK~!! %)

1. I think the causes of dying coral reefs are wastes dumped by people and water temperature changed. Now many of the wastes in the sea is hard to remove. And humans have to sacrifice for nature and have to try much more for earth. 2. Many people think the cause of effects of the continuing rise in earth’s temperature are humans indiscreet behavior. But this is only a small cause. The big cause of global warming are cows. Cows\' burps, farts, feces make global warming seriously. And cows\' burps, farts, feces have much methane gas whcih making causes global warming. So scientists are trying to make an equipment to a cow. The equipment makes to reduce methane gas of cow. But it might make many problem from animal protection group And scientists are trying to solve through feed.
