speech on water pollution:
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.This water index is not congruent with the development index. For example, the US – one of the most developed countries – ranks 33rd on the water index. Experts calculate that 20 per cent of world population in 30 countries faced water shortage in 2000 which would climb to 30 per cent in a total of 50 countries by 2025.
Water pollution is one of the world's worst forms of pollution. For example, take a look at a glass of water. It may appear clear, but there are really millions of microscopic pollutants floating in it. Approximately 70% of the earth's surface are covered by water; water is a very dynamic system, any change in its normal content could affect local, regional, and eventually worldwide water.Oil is one of the world's biggest pollutants; oil is usually spilled or leaked from land or rivers and flows from them to the sea or ocean. The more direct form of oil pollution is when ships transporting oil leaks or the ship crashes. Oil can also ruin shores it can was up on them and become tar like lumps; some coat fur of animals and can effect their heating system. Also some oil can find its way into other sources causing hazardous water to be consumed. In some extreme cases, rivers, lakes, and wells have been known to ignite.
Here are some tips which really will help us to save water:Parents should aware their children about the need of water conservation. They should avoid buying recreational water toys (which require constant stream of water) to their children.Everyone should be aware of the water shortage rules and restrictions and strictly follow in their own area.Every employee should be active for the water conservation at their own work place and encourage their employer to promote water conservation in other effective ways.There should be water conservation awareness and tips for every starter in the orientation manual and training program at schools, colleges, work place, offices, institutions, etc.Water conservation techniques should be promoted on every news media such as TV, newspaper, radio, FM, community newsletters, bulletin boards, banners, etc.People should be more active in their area to report (to their owner, local authorities, water management of district) any problems related to water loss through broken pipes, errant sprinklers, open hydrants, abandoned free-flowing wells, etc.Water conservation awareness should be highly developed and promoted especially in the schools to aware children means future of the nation.School students should be assigned to prepare projects on water conservation or given this topic during any competition like debate, discussion, essay writing or speech recitation.It should be promoted at tourism level so that tourists and visitors can be aware of and understand the need for water conservation.As being educated citizens we should encourage our friends and neighbors to join the water conscious community.Everyone should make a task related to water saving and try to complete by the end of day strictly.
