I read an article about that eating vegetables ,like lettuce, cucumbers and eggplants are worse to Environment than eating meat because growling plants uses more energy per calorie than animals for meat. It is the direct opposite of the common sense about effects of eating meat on environment. But I don’t think this calculation is right because I know growing cows and pigs requires a lot of amount of plants also.= need to eat plants to grow. I know one of main reasons to be vegetarian is to preserve the earth from greenhouse effect caused by carbon emission generated when growing animals. Also I= I also  know that one of the best solutions of world poverty as well as reduction of carbon emission is to produce fish under ocean by mass production. According to the news, to produce fish by mass production could be not an environmental friendly solution. Now I’m very confused whether eating meat is more harmful to environment than eating vegetable or not as well as whether global warming is really a big threat to human or not. Because a lot of scientists argue = have argued that these phenomenon are normal in the long term point of view. There are too much statistics for ordinary persons not to easily understand= There are many scientific consensus on global warming but it is not easy for us to understand
