When we use it to talk about a world problem, it means people who feel that a lot because they don’t have enough food.

8. This can happen for a couple reasons:
Poverty – People don’t have enough money to buy food
Famine – There isn’t enough rain or good weather to let food grow, so people go hungry
War – There isn’t enough food to go around during times of fighting

11. Pollution

12. There are several types of pollution:
Air pollution – dangerous gases or dust go into the air, making the breathing air more dangerous and unhealthy
Water pollution – dangerous things in the water that make it unhealthy to drink or unsafe for the animals to live in
Land pollution – things put in or on the land to make it not safe or not wanted

24. Disease
A specific illness, or illness in general

25. Disease is such a problem because it often is easily fixed with medicine, but isn’t because of poverty and hunger.
When people are hungry and live in poverty, they often have bad food and unclean living conditions. This makes their bodies unhealthy, and easier for them to catch diseases.
There are also many diseases that aren’t fixable yet. There is no medicine to cure (治疗) them.

HIV (艾滋病)
Polio (脊髓灰质炎)
Cancer (癌症)
Diabetes (糖尿病)
Tuberculosis (肺结核)
