The solution is to filter the water and give free water to the people who can’t get clean water. They could use a life straw that purifies your water and cleans it, or you could boil the water or use iodine solution. Another way to clean the water is chlorine drops or ultraviolet lights, as you can see, there are many ways to clean your water. There are many affordable ways to clean your water like non electric water purifiers. Even the ‘Life Sack” and “Life straw” can clean water and they are very cheap and artable. So many people can buy them. Also you could help us raise money to buy water purifiers for families too. When produced in quantity, each Life Straw — which uses a combination of mesh filters, iodine-impregnated beads and active carbon to remove particulate matter and bacteria — is expected to cost under $2 and be able to provide a year's worth of pure drinking water. So if we were to buy 1 billion, it would cost 2 billion dollars.
