Water pollution happens when waste things from many areas are thrown into rivers, lakes and seas.

Agriculture

To get more food, farmers use large amounts of chemicals (化学制品). When the chemicals are not completely used by the plants, they are washed away by the rainwater into rivers, lakes and seas, which pollute both surface water and underground water.

Industry

Factories and industries often release poisonous chemicals into seas, rivers or lakes, which is quite bad for Mother Nature. An example of industrial sea pollution happened in Japan in the 1950s. A local factory had poured waste water with mercury (水银) into the Minamata Bay for 20 years. Tuna fish in the bay took in the mercury and people ate the tuna. Many children were born with birth deformities (畸形). As a result, people lost their hearing and sight, and thousands of people died in the end.

Sea transportation

When ships transporting oil get damaged on the way, oil spillage (溢出) happens. One major disaster was the Exxon Valdez oil spill. An oil tanker sank off Alaska in 1989 and leaked (泄漏) oil into the ocean. To save cost, some ships also poured unwanted oil from their engine rooms into the sea, thus polluting the oceans.

Home activities

If the waste from the washing of clothes and dishes are not treated and poured into the sea, they will do harm to the sea life. Some diseases may also spread. Sometimes, rubbish is dumped into the sea.

One of the most interesting projects in oceanography(海洋学) is the work of mapping the ocean floor. Only a very small part of it has been mapped .This was not important when only surface ships sailed the world’s oceans, but it can mean the difference between life and death to men in submarines(潜艇).

 Long ago there was only one way to find out how deep the ocean was .A seaman could throw a weighted rope over the side of his ship. Then he pulled the rope up after it had reached the bottom. But this was not a very exact way of measuring.

  In the twelfth century a better way was found. Sound was used to measure the ocean. An American Navy ship sailed the ocean to make an experiment. Seamen dropped a number of devices that would give out a loud noise when they hit the bottom. And a device had been invented measured the time it took for the sound to reach the ship .It helped oceanographer map the ocean floor.

Underwater photography is also important in mapping parts of the ocean floor. With the new methods that have been perfected, cameras can take pictures of the underwater valleys even in color.
