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.

When an animal helps another animal, it usually gets something valuable in return. For a long time, many scientists thought that only people could act generously just because it feels good.
However, a new study in Germany suggests that chimpanzees (黑猩猩)also do good things for no real reason. And so do children who are as young as 18 months of age. Maybe it is because humans and chimpanzees share an ancestor(祖先) about 6 million years ago.
People and chimpanzees appear to develop such features(特征) without any other training, says Warneken, a scientist in Germany. Warneken and his partners worked on adult chimpanzees that live on an island in the African country of Uganda. They also worked with 18-month-old children in Germany. The researchers performed three experiments on the adult chimpanzees and two experiments on the kids. In the first animal experiment，a person tried to reach his arm into a cage to get a stick，but he couldn’t reach it. A chimpanzee was in the cage，and it could reach the stick if it wanted to.
Thirty-six chimpanzees took part in this experiment one by one, and no chimpanzee saw what the other chimpanzees had done. Even though the animals hadn’t met the person before, they usually took the stick and gave it to the person. What’s more, they did this whether or not the person offered them bananas as a reward. In a similar experiment, 36 children acted in a similar way. They helped the person reach the stick, whether or not they were offered toys for their help.
Researchers did other experiments on chimpanzees and babies. No rewards were offered in either experiment. And still, both the chimpanzees and children went out of their way to help. Still, the new study is different from earlier findings. Researchers have found that chimpanzees don’t give rewards of food to other chimpanzees, even if it costs them nothing to be generous.Warneken and his partners worked with ________.
| A．young chimpanzee that live on an island |
| B．18-month-old children who live in Germany |
| C．kids who are living with adult chimpanzees |
| D．adult chimpanzees that live on the African mountain |
A new study in Germany suggests that ________.
| A．people also share information for good reason |
| B．children know something at the age of 18 months |
| C．chimpanzees do good things for no real reason, too |
| D．humans should develop their abilities 6 million years ago |

| A．Thirty-six chimpanzees joined in this experiment one by one |
| B．No chimpanzee saw what the other chimpanzees had done |
| C．The animals hadn’t met the person before the experiments |
| D．Chimpanzee gave the person the stick in order to get a reward |

| B．chimpanzees will reward good food to other chimpanzees |
