Question: Read the article and select the best answer. Article: It is not a question of culture, it is not even a question of killing animals. Even a carrot dies when pulled out of the ground. It is a matter of the protection of the planet because our meat eating habits might be stressing (......) our ecological ( ) system. It's no longer --might||, we are destroying our planet. Most of the meat that we eat comes from livestock, which is about 23 billion in population and causes the waste of our natural resources. Every second of every day one football field size rainforest is destroyed, and much of it is used to farm and raise livestock. Raising the animals also requires huge quantities of water, mostly to grow the grains fed to them. It takes over 2,000 gallons of water to produce one pound of beef, which can be used for a seven-minute shower every day for a minimums of four months. Take your pick: four months without a shower or a hamburger. Meat has to be cut, cleaned and processed. One doesn't just buy a cow and start eating it. According to David Pimentel from Cornell University, it takes 20 times more energy to produce beef than tofu, and both have the same good sources of protein ( ). The waste from the animals is one of the main causes of water and air pollution. The animal waste cannot be used in the fields because it can spread diseases to humans. In 1995, 25 million gallons of animal waste flowed into the New River in North Carolina, killing 10 million fish and destroying 364,000 acres of coastal ( ) wetlands. Animal farming also produces larger quantities of greenhouse gases, such as methane (CH4) and nitrous oxide (N2O). If your next Christmas is unusually hot or especially cold, blame the steak you ate the night before. I am not saying that everybody needs to stop eating meat right this minute. I don't think we can produce enough corns, fruits, and vegetables. I am just saying we need to cut our meat consumption , 70 grams per day is okay if we want normal weather, clean air and drinking water. Question: From the passage, we can learn that . Options: A: animal waste should be used for planting B: we're destroying the farm to raise animals C: animal farming produces greenhouse gases D: we use the same energy to produce beef and tofu

C
