The simplest water pollution definition would be any contamination of water bodies with some pollutant(s) that changes physical, biological, and chemical conditions of any body of water making this water harmful for environment and surrounding ecosystems.Water pollution occurs once too much pollutants (mostly in form of different waste) are discharged directly or indirectly into water bodies. Water pollution does not only cause great environmental damage but is also the leading worldwide cause of deaths and diseases responsible for the deaths of more than 14,000 people each day, mostly in developing countries.Many people are not aware that water pollution is serious problem in almost all parts of the world, and not just in third world countries like some choose to believe. In fact many experts will tell you that reality is completely different than the common belief, and that actually water pollution problem is already out of control.Water pollution problem is in most cases connected with the careless handling of chemical agents, toxins introduced into our water through industrial dumping, and farm runoff. All these factors make our water unsafe to drink.For instance, the chlorine that is widely used to disinfect our water is believed by many to be carcinogenic, and therefore a major health issue that significantly contributed to worldwide rise of cancer rates.Basically chlorine is present in every glass of water we draw from our tap, and although some studies have confirmed that chlorine can indeed be one of the cancer risk factors we simply cannot do without it because by removing chlorine from our water we would open the door to many waterborne diseases that would kill millions of people around the globe.So how to protect yourself from water pollution? The best option available to us is to install a multi-layered home water filtering system in your home. The best option is multi media block system that has an activated granular carbon filter, a sub micron filter, and an ion exchange. This system is capable to prevent up to 99.99% of all of the harmful contaminants present in our water from entering your home.High quality home water filtering system is really your best ally against water pollution.网上找的这篇，符合你的基本要求了，希望能帮到你。

Oceans To Hold More Plastic Than Fish by 2050
There will be more plastic than fish in the world’s oceans by 2050 unless more recycling takes place. That is what a new report from the World Economic Forum and Ellen MacArthur Foundation warns.
塑料垃圾已经泛滥成灾了吗?今年1月，达沃斯世纪经济论坛和艾伦·麦克阿瑟环保基金会(Ellen MacArthur foundation)发出的警告引发人们热议：到2050年，世界各大海洋中的塑料垃圾总重量将超过海中鱼类。这样的警告是危言耸听吗?
If the current trend continues, the report said, oceans will contain one ton of plastic for every three tons of fish in 2025.
By 2050, plastics will weigh more than fish, the report said.
The problem is that each year at least 8 million tons of plastics end up in oceans around the world.
The report said this is the same as dumping the contents of one garbage truck into the ocean every minute.
Not all plastic ends up in the ocean because someone throws a plastic bottle into the water.
Plastic containers and other trash thrown onto streets and sidewalks often are swept into oceans. The debris travels from storm drains during rain storms, said the environmental group Marine Defenders.
Some end up in gyres. A gyre is a big whirlpool that traps and moves the plastic in circles.
Unlike other types of trash in the ocean, the plastic never bio-degrades. That means it does not break down.
There is a way to slow the amount of plastics going into the oceans -- people can recycle more. That is a major recommendation of the report by the World Economic Forum and Ellen MacArthur Foundation.
The report’s authors say that currently only about 14 percent of plastics are recycled.
It said research in Europe shows as much as 53 percent of plastic could be recycled using available technology.
The report says that another solution is using less plastic for packaging products. But that is not likely to happen, the report’s authors say.
