X. Study the text and name the problems connected with water pollution:

Water Pollution

Worldwide, the most serious water pollutants, in term of human health, are pathogenic organisms from human and animal wastes. Effective sewage treatment systems are needed that purify -wastewater before it is released to the environment

In industrialized nations, toxic chemicals wastes have become an increasing problem. Agricultural and industrial chemicals have been released or spilled into surface waters and are seeping into groundwater supplies.

Ultimately, all water ends up in the ocean. The ocean is so large that it would seem impossible for human activities to have a significant impact on it, but pollution levels in the ocean are increasing

As much as 80 percent of all disease and some 25 millions deaths each year may be attributable to water contamination.

Discarded plastic flotsam and jetsam are becoming an ubiquitous mark of human impact on the oceans. Since plastic is lightweight and non-biodegradable, it is carried thousands of miles on ocean currents and lasts for years.

Few coastlines in the world remained uncontaminated by oil or oil products. Oceanographers estimate that somewhere between 3 million and 6 million metric tons of oil are discharged into the world's oceans each year from both land- and sea-based operations. About half of this amount is due to maritime transport.
