The water sources are being more and more polluted. In my opinion, the main reason is people don't keep their responsibility. Many people keep throwing trash on the beach and it makes the water becoming more and more polluted. Another thing that also affects so much to it that the waste in the factory. Some factories even contaminate people's water sources and if we drink the water which has been polluted, we may get suffer from many diseases or worse is die. One more reason is we have wasted too much water in our life. What we should be done now is to advise people to keep their responsibility and tell everyone to stop littering when they go to the beach. This little thing is meaning a lot to the environment too. One more thing that we can do is to reduce the waste from the factories. The chemistry which comes from the factories makes the water polluted. We must reduce the waste of water in our life too. Not only us, but the water polluted do also effect to other kinds of animals too. If they drink that water, they may get sick and die and some animals kind also may get extinction.
