As we know, weather and climate can affect people in a number of ways.
Farming and climate   Farming is directly linked (联系) to weather and climate. For example, wheat needs dry, warm and sunny weather to grow while rice needs wet, hot and rainy weather. Farmers have to decide what to grow according to the weather in their area. When there is a sudden change in the climate, it will affect farming and food production around the world.
Climate and people’s health   A change in weather will also cause changes in food, air and water qualities. So it will have a deep effect on people in the future. Changes in weather and climate can cause infectious (传染的) illnesses to spread among people because germs (细菌) can be easily spread through air and water. 
Climate and water resources   A climate change would influence the water system across the world. For example, in North America there is so much rain that towns and cities are often flooded. However, in North Africa, people can die of thirst because of being short of water.
In recent years, as a result of global warming (全球变暖), we suffer a lot from extreme (极端的) weather each year and it is the duty of the whole world to control the climate change and save our own planet – the earth.
