Transcript of The World's Water Problems

Every year 3.4 million die from a water related disease. That's almost the entire city of Los Angeles! LOS ANGELES The World's Water Problems Water Source Home Everyday, women spend a total of 200 million hours collecting water. More than half of the world's fresh water supply is contained in just nine countries. United States Canada Columbia Brazil DR of Congo Indonesia China India Russia The Top 5 Countries With The Least Fresh Water 1. Somalia 2.Mauritania 3.Sudan 4. Niger 5. Iraq -Although some of these countries are surrounded by water, they lack resources to purify it

-Natural sources of clean water in these countries are polluted or contain diseases. Even in developed countries, issues with unclean water also occur Chilliwack An example includes the recent Chilliwack's problem with E.coli infected water Imagine this happening to the children in developing countries everyday with little or no health care, the dangers are much higher.

In fact, 5,000 children die every day from diarrhea caused by contaminated water, or one every 17 seconds.

This means, by the end of our presentation, around 32 children will have died. water > Water, worth more than gold as a necessity of life, is crucial for survival and is the most important resource in the entire world gold YET over a billion people do not have access to clean water, thus never living a healthy life Top Three Barriers in Solving The Problem - Ineffective Governments
Developing countries are clearly far more susceptible to this problem than developed countries, and the unfortunate fact is, developing countries’ governments are highly ineffective compared to their developed counterparts. -Funding
Many of the developing countries are debt stricken and unable to strain their limited resources on solutions. Especially in the recent economic recession. -Mentality
Changing the mentality of people in developed nations will be difficult, especially when they use water like how they breathe. Four Possible solutions in relieving water stress. 1. Desalination Technology The Pros? -Simple, turn the plentiful saltwater into fresh water The Cons? -It's ridiculously expensive, so the poor nations can't afford it, where clean water is most needed.

-Requires lots of energy, leaving a large carbon footprint, unless somebody finds a solution to the world's energy problem 2. Treating Waste Water The Pros? In developing countries, 80% of diseases are spread through consumption of infected water -Cleaning and recycling used water can help reduce the need of fresh water from natural sources, allowing water to be sustainable. The Cons? -Again, this solution is expensive and uses large amounts of energy that the poor nations simply cannot, therefore can only be used in developed nations.

-People will have a hard time thinking that the water has been used by someone else, no matter how thorough the cleaning process was, making use of this water uncomfortable. 3. Tell People To Use Less Water! 4. Stabilize the World Population The Pros?
- By slowing our speeding population increase, we will relieve strain off of water depletion in certain areas. Smaller population = Less amount of water consumed The Cons?
- There is no methodology proven to be both effective and practical enough to have been enacted as of yet. The concept must be brought to reality.

-The effects are not immediate, because it may take generations and years to finally stablize the population, which by then would already have a different situation. Conclusion: Over 3.4 million people die annually due to water, sanitation, and hygiene-related cause. 99% of which occur in developing worlds. Water crisis constantly effect people around the world and should not be overlooked for it is a staple resource. Future generations will not survive and death rates in developing worlds will continue to rise if we do not make a change. Water will either deplete or become too unsanitary to use. Ideas of possible solutions have been drawn up and now it is our responsibility as consumers to help them succeed. The Pros? -Keeping down water usage will help keep water sustainable. -A simple idea: use less water = more water in the long term The Cons? -Many people fail to address this problem in the developed world, as they are accustomed to taking water for granted. -This may only slow down the problem for the time being, but the problem will still arise in the long run.

-This solution alone cannot solve the problems, it has to used in synergy with another solution to become effective. Important Facts! A five minute shower in America uses more water than the average person in a developing country uses for an entire day. Thank You! Now let's go save the world! 70% of the world is covered by water yet only 2.5% is fresh and drinkable water. Brief History: -Not too long ago, water was thought to be in infinite amounts.

-Water stress was basically non-existent in the past, as the global population was only a fraction of the current population.

-Now, people in the developed countries take more than ever before because of the demand for water to feed livestock and for agriculture.
