Paragraph 1: The global shortage of water
The world is running out of fresh water and it is a necessary resource for humans to live, so, we stand today on the edge of a major water crisis. We need water for drinking, cooking, washing, for food, energy, industry and finally and most importantly for living. In general there is a lot of water on earth as can be seen from space, and our planet is covered with it, but the problem is, this water is not available for drinking, because it’s salty water from the ocean. Only 3% of the earth’s water is fresh water and 1% is enough for the whole world, but only if it’s used rationally. Many developing countries don’t have access to fresh water. Poor countries in Asia, Africa can’t afford to use new technologies for containing and purifying water to prevent a water crisis. The water in those countries is scarce, polluted and dirty. Yet, people are still drinking this kind of water to survive, and that caused many serious diseases such as cholera and has led to the death of lots of people. Population growth is another problem and there is not enough water to meet the needs of everybody. Future generations may face catastrophic consequences if we do not solve this problem. There will not be enough for everybody to drink and some countries will suffer as other people in the world, will panic and some will use violence, which will cause wars in the future. Paragraph 2: Problems of the country
The problem of water shortages in most poor Asian countries is caused by the pollution of clean water. One of the countries I have chosen to write about is Bangladesh and I will list the problems it’s facing due to the shortage of water. The population in Bangladesh is growing so fast that improvements in the water supply have failed to keep pace. Seventy eight percent of the people in Bangladesh still have no access to clean water, and water contaminated by sewage is estimated to kill thousands of people, including children, every year. There are plenty of rivers in Bangladesh, but unfortunately most of these rivers are polluted by fertilizers, pesticides, silts, sewage and other toxic effluents dumped by factories. The government can’t stop the production of the plants that are polluting the rivers because they don’t have enough budgets for alternative change, and also if they tried to stop it, food prices would go up and hunger and thirst will prevail through the whole country. It’s unfortunate because it’s human activity that is playing the major role in creating water scarcity and water stress.
Paragraph 3: Solutions
New methods have been introduced by scientists and experts to solve the water crisis problems in Bangladesh. As we know, Bangladesh is a country going through economic decline and it can’t afford to finance expensive projects to solve the problems people face regarding the water crisis. Most of the wells and ground water in villages are polluted by arsenic which is a substance that contains iron iodide. Scientists had designed a mineral that is called “getter” and its function is to remove all the arsenic in the water, and eventually leave clean water available for drinking. Another process is called distillation, which is a safe and clean process and normally used by developed countries, but takes a lot of time and money. “Existing methods of arsenic cleanup, including distillation, would cost hundreds of millions of dollars," Brady says (scientist from the International Atomic Energy Agency (IAEA)). (Kate Melville, 2000). Fog water collection is a new technology that has already been set up in some high altitude villages; this technique is very easy to use and doesn’t cost much. The technology works by stationing a plastic mesh in a place where fog pass through it, usually in high places, it traps tiny drops of water and send it in tubes to the water tanks that are placed inside the village. There are many other solutions to stop the water crisis in Bangladesh but the government should take necessary step forward to solve the problems.Paragraph 4: Conclusion
Briefly to summarize, the increase in the population, the drop of economic activity and inadequate supervision by governments of factories in Bangladesh are the main factors that have limited the possibility to solve this problems and find a solution to the water crisis. However recent development, indicate that Bangladesh can find a solution with lower cost to minimize it’s losses such as the Fog Collector. This solution can increase the water supply to many families and decrease major diseases caused by polluted water. Bangladesh has many natural resources that it could benefit from, but the government needs to focus more on improving the country.
