If it doesn't produce grain, of course, it's even less feasible.

要是不生产粮食的话，就更不可行了。

The fields would produce grain and the forests would supply lumber for their houses.

许多的田地将产生谷类和森林将供应木材给他们建屋子。

This would raise the prices not only of products made directly from grain, such as bread, pasta and breakfast cereals, but also of meat, milk and eggs, which take large quantities of grain to produce.

这将大大提高粮食的价格，不仅包括那些直接从粮食产出的产品，例如面包、意大利面和谷类早餐，而且还包括肉、蛋、奶等价格，这些产品都需要大量的谷物才能生产出来。

The environmental equation of tracking animal production from feed to table goes like this: to produce a kilogram of beef, farmers have to feed a cow 15kg of grain and 30kg of forage.

跟踪动物产品的养殖到餐桌的环境方程序是这样的：生产1公斤牛肉，农民必须给牛喂15公斤谷物和30公斤草料。
