Introduction

Water is the source of life. As the Climate Change in recent years has become more severe, the lack of water is getting serious, and makes people start to take the lack of water resources seriously.

Warning!!!!!

Warning!!!!!

The reason of water shortage(Huiwen Zeng)

For the hydrological conditions in Taiwan, the annual average rainfall is about 2,510 mm , and the narrow terrain makes the mountains steep and the

river steep down quickly.

We can't efficiently use the rain water,and there is an uneven distribution of precipitation. About 78%of the

rainfall falls between May and October.And typhoons and terronial rain often cause disaters.

Uneven of precipitation.

Water Crisis and

The negative impact

(Yingrong Chen)

1.The short of available water

◎Crop reduction

◎ Lead to conflict and war

◎The lack of sanitary water

2. Water pollution

◎Endanger biodiversity

◎Disease and death

The distribution and status of water resources

in Taiwan (Zihan

Qiu)

The change of rainfall patterns

• It is the amount of annual rainfall that happenes in a very short period of time. Such rainfall not only makes us be unable to utilize water resources efficiently but leads to floods and droughts.

• Another is that the rainwater should fall in the reservoir catchment, but it turns out to fall in the downstream of the reservoir or at sea, which makes us be unable to effectively block the water and utilize it.

Q1.What are the characteristics of Taiwan's rivers? What are the advantages and disadvantages of these characteristics?

1.Rivers in Taiwan flow westward or eastward because of the separation of the Center Mountain Range, which runs from the north of the island tothe south.

2.The short length of rivers.

3. There is a big variation in the amount of river water.

Q2. Why should we build reservoirs? What the reservoir do to save water for help?

Differences in the price of water and water-saving methods between Taiwan and other countries

3.Saving method

(1).Popularize the water-saving machine (buying the water-saving equipment is subsidized by the government. )

The water-saving toilet

(2). Promote the water-saving Mark and System

(3).recycle the water and ReuseProviding the plants can reduce 35% of the

Domestic water

Epilogue

Environmental damage caused by humans may lead us to a hopeless futureIf we still continue polluting the nature, and don’t do somethihg to save our world.We will lose the clean water, sky, air, and finally our living environment.
