5.What do you usually have for lunch?Indeed,for many of us,meat has been part of our diet for years.
For your American peers,however,school lunch might have to change this year-there could be less meat and more fruits,vegetables,nuts,whole grains and other plant-based foods for them in future.
Their new diet would encourage Americans to eat more healthily.But it could mean much more than that.According to the Fox Business website,the new school lunch also looks at what is healthy for the environment.A diet higher in plant-based foods and lower in animal-based foods causes"less environmental damage than the current average US diet",a research from a US government committee said.
No matter how tasty you think meat is,it seems to be causing problems for the environment.Researchers from the International Livestock(家禽)Research Institute in Kenya and the Commonwealth Scientific and Industrial Research Organization in Australia and the International Institute for Applied Systems Analysis in Austria looked at the livestock industry around the world and found that it is adding to climate change.
In poorer countries like Ethiopia and Somalia,1,000kg of carbon is produced for every kilogram of protein produced by cattle.This happens because of the methane(甲烷)gas that comes from the cattle's manure(糞便).When forests are cut down to make land for livestock like cattle,the trees can no longer absorb carbon,which then goes to the atmosphere.
Although groups like the National Cattlemen's Beef Association in the US are unhappy with the idea,environmental groups would be happy if the changes happened."We need to make sure we think about our natural resources and the need to reduce climate change when we choose our diets,"said Karl Hamerschlag of the group Friends of the Earth.
So,would you give up meat for the good of the environment,or does beef taste too good for you to support these plans?
