Take care of the water (7A_提高_P66)

Imagine a mass of floating waste that is twice the size of the state of Texas. Texas has a land area of more than 678,000 square kilometres.

So it might be difficult to imagine anything twice as big.

This mass of waste flowing in the North Pacific Ocean is known as the Great Pacific Ocean Garbage Patch, It weighs about 3,500,000 tons, The waste includes bags, bottles and containers plastic products of all kinds.

The eastern part of the Great Pacific Ocean Garbage Patch is about l,600 kilometres west of

form where big rivers meet oceans. The force of water running in rivers and streams changes the shape of land in many ways.

Rivers and streams have many uses besides carving land. People use rivers for swimming boating and fishing. People also have used rivers for thousands of years to transport goods from place to place. Today, large barges and ships move cargo over rivers. Lumber companies move logs fromforests to mills over rivers.

Streams and rivers are home to many living things. People and other animals depend on streamsand rivers for drinking water. However, some industries and large cities dump their waste into riversand this waste pollutes the water. Polluted water is harmful to humans, plants and other animals thatlive in the water or use it to stay alive.
Let's take care of the water for the good of the earth.
