A) rising, b) areas, c) global, d) drought and famine, e) temperature

The higher average temperatures produced by global warming could cause dramatic changes in weather patterns. Less rain might fall over large land masses; Central Africa, South Asia and some parts of the United States could risk severe 3___. More rain might fall in coastal 4___and over the oceans, and there might be more storms and hurricanes in the Pacific. A rise in the earth's average temperature of only one or two degrees would probably melt the polar ice caps and raise sea levels.

1. Imagine а world with no drinking water, and no water to wash or cook with. It’s hard to imagine this, because we use water every day without even thinking about it. Yet there are terrible water shortages all over the world. In parts of Africa or China, for example, many people don’t even have clean water to drink. In fact, over half of the people in the world have to live with water shortages every day. We all need water – not just for our homes and factories, but to survive. Fortunately there are things that we can all do to save water.

2. The solution begins at home. We can save the water from our baths and use it for the garden, instead of wasting hundreds of liters of clean water on our lawns and plants. This would help to save many liters of water everyday, especially in the summer.

3. Governments can help by passing laws to stop factories from wasting and polluting water. If factories recycled water and stopped pouring chemicals into our lakes and rivers, there would be a lot more clean water around.

4. Government could also stop water companies from wasting millions of liters of water because of leaking pipes. Many cities have successfully saved water by repairing pipes.

5. All in all, there are many things we can do to save our planet’s disappearing water supplies. The time has come to start understanding the value of water, before a world without clean water becomes a terrible reality.
