Question

a speech on how to prevent water pollution

Answer 1

Answer:

HEY HERE IS YOUR ANSWER.

Explanation:

Water is the most important natural resource for life. Human being needs water not only for drinking but also for cooking, washing, irrigation, fishing etc. People have been abusing and misusing water since long. Industrial wastes, garbage and other remains of used commodities have been getting dumped in rivers and oceans causing contamination of water. It is also contaminated of toxic chemicals discharged from factories, pesti­cides used in agriculture and so on.

Due to the poor water supply system, contact of sewage with the water supply line contaminates water used for drinking. Contaminated water has become a serious threat to human beings, fish and the animals. The poor and less developed countries are facing greater problem of water pollution as they have dilapidated water treatment and supply system and also lack in proper waste disposal system.

They dispose waste products and garbage straight away in their rivers and lakes. About one-third population of the world does not have access to safe water. A very common water-borne disease is diarrhoea, which is caused by contaminated water. It is very common in poor countries and in the segment of poor people of less developed countries.

Developed countries are almost free from the problem of water pollution. Pollution of water in those countries is mainly due to the excessive use of pesticides to protect agricultural crops. Water pollution in these countries is not due to the lack of management of garbage as in the less developed countries for whom its disposal and treatment is normally unaffordable.

However, the developed countries are not confronted with the problem of water contamination as much as the poor ones because they have sufficient resources and efficient technology for treatment and recycling of sewage, garbage and domestic waste.

A team of researchers at Britain’s Centre for Ecology and Hydrology and experts from World Water Council introduced a new index of water-rich and water-poor countries. Five different criteria were used to construct the index: resource, access, use, capacity and environment.
