A new study showed that one of the best ways to control greenhouse gas emissions(温室气体排放) is to eat less meat. In fact, the study showed that meat consumption(食用量) in developed countries should be cut by 50% per person before 2050.
Meat production and consumption are expected to rise very quickly to a high level by 2050. That’s because the global population is expected to grow from the present 7 billion to 9 billion. But also, the diets of people in many developing countries are changing. Countries that are developing rapidly are seeing a fast rise in protein consumption, especially red meat.
Dr. Eric Davidson, the president and senior scientist at the Woods Hole Research Center in Massachusetts, said changing the way people eat can have a great effect on greenhouse gas emissions. People in developed countries, he said, already eat much more protein than the daily requirement.
“In the developed world, there is large room for us to manage the frequency with which we eat meat. If there is a growing need for meat, that is going to end up requiring use of more nitrogen fertilizer(肥料) and production of more livestock manure(家畜粪肥), both of which end up resulting in release of various forms of greenhouse gases to the atmosphere,” he said.
Davidson said farmers should be encouraged to use fertilizers and manure in a more careful way. “ If we want to meet the greatest goal of making harmful climate change under control, we need to improve the efficiency(效能) with which we use fertilizers in agriculture. We need to improve the efficiency of the management of manure. And we also need to consider changes in dietary patterns(饮食方式). And that means hopefully better diets in the developing world and better balanced diets in the developed world,” he said.
Even if it were possible to turn off all harmful greenhouse gas emissions today, he said climate change would continue. “ But that does not mean that we can do nothing for it now, because the sooner we start to take action, the more choices our children and grandchildren will have in terms of being able to feed themselves and have comfortable lifestyles without environmental degradation(退化),” he said.
