Mary wants to do something for our earth, because the environment on the earth is getting worse and worse.

A. We provide volunteers with training lessons. With the help of these lessons, you can know what to do when you are a volunteer.

B. There are fewer trees on the earth, so the air gets worse. We can volunteer to plant trees in the parks and mountains. If you can, come and join us.

C. Do you feel sorry for those homeless animals? Here you can do something for them. We welcome you to work with us when you are free.

D. Who wants to help care for sick dogs and cats? If you want to be one of us, you should be able to work at least 3 hours a day.

E. There are many children without parents. We help to provide them with good education. We also give out food and clothes here. Become a volunteer today!

F. At least 130 million people around the world do not get enough health care. This is often because there are no workers with professional skills to take care of them. We need the right workers with the right skills.
