   Is it possible to have a diet（日常饮食）that’s both healthy and friendly to our planet? Here are answers to your eco-friendly food questions.

Does what I eat influence climate（气候）change?

Yes. The world’s food system is responsible for（为……负责）about one quarter of the planet—warming greenhouse gases that humans produce each year. That includes raising and harvesting all the plants, animals, and animal products we eat, as well as processing, packaging, and shipping food to markets all over the world.

Which foods have the largest influence?

In general, beef and lamb have the biggest climate footprint per gram of protein while plant—based foods like beans, rice, corn and wheat have the smallest influence. Pork, chicken, eggs are somewhere in the middle.

Is there a simple food choice I can make?

Studies have shown that people who eat a meat—heavy diet can reduce their food—related footprint by one third or more by moving to a vegan diet — no meat, dairy（乳制品）, or eggs. If you don’t want to go that far, just eat less meat.

Can I really make a difference to our planet?

We need more food to feed the world’s growing population. One person alone can make only a tiny difference. If many people make changes to their diets, that will start to add up. It will make a greater difference if the world’s heaviest meat eaters make some changes to their diets.
