Ways you can help

A few ways to help lessen the effects of water pollution and water pollution its' self are: Bringing your own bag to your local supermarket to shop, try not use plastic bags and bottles (plastic bags can take 1,000 years to biodegrade), try to recycle as often as you can with anything able (plastic jugs take upwards of 1,000,000 years to biodegrade), don't use styrofoam at all unless recycling it (it takes over 1,000,000 years to biodegrade). Volunteering with NGO's in your area and other groups trying to stop water pollution is a great way to help and protect your environment. Many organizations accept donations which is also another way to help if you don't have the time to get out yourself. But, all in all the best way to help out water pollution is to not cause it, recycling your plastics and trying to live a sustainable life wil help out greatly in the fight against water pollution.
