in my topic is born a problem that is the pollution of water is an irreversible phenomenon?
In my opinion it's not because if everybody are committed we can resolve this problem.
what is your opinion??
Pollution of water irreversible phenomenon ??

In order to prevent water pollution
Sewage treatment systems must be founded
The overpopulation must be reduced in certain areas.
Communal conscious must be awaken
Important policies and plans must be developed in order to save the natural resources
The factors that cause air and water pollution must be eliminated
These precautions must be put into practice immediately. Otherwise, it will be too late, and we will lose lots of things.
I agree with francidona.
I agree with francidona. "This kind of solution may be too focused on the present and does not solve the problem once and for all, I believe this could save thousands of people, as waiting for sewage treatment plants to be built in developing countries would require too much time."
I think that's absolutely true!
this problem is new.many
this problem is new.many people don't know this problem and they don't trying solve this problem.
agree with Francidona: action on household-level purification
Hello!
I agree with Francidona: household-level purification is often almost as good as large sewage treatment plants and it has the great advantage of being much cheaper, which allows it to be applied to poorer countries.
So, we must ACT, by building these kind of stations on household-level and by talking about these issues and so giving them importance, thus pressuring authorities to act and to divulge this solution.
technology
Technology is the only real means of improving our lives. We've got to use it and invest into it. Because if only the "rich" will have acces to the clean water just by keeping it all for themselves and making it more expensive for other people (thus creating scarcity) -not cleaning water just for pure profit- and not using the technology to clean the already polluted water they will soon have compete for water themselves.
In fact not irreversible
Hello!
In fact it's not a completely irreversible phenomenon, as there are several ways to treat water.
Some of them are complex and expensive, while others are amazingly simple and remove water impurities almost completely (I already heard one that included simply some kind of filaments).
We must in deed explore them as water becomes scarce, instead of accepting that polluted water can never be used again.
Household-level purification
Water can be recycled, otherwise I believe there would be much bigger water shortages everywhere.
Sewage is purified before being poured into the sea or into rivers. This is what happens in developed countries. However, as sewage treatment cannot be always provided at this level, in some countries sewage is still a cause of water pollution, leading to infections and diseases. But to fight against this, systems for water purification at an household level have been developed. They are also called "point-of-use water treatment systems", and they include solar disinfection and ceramic filters.
Although this kind of solution may be too focused on the present and does not solve the problem once and for all, I believe this could save thousands of people, as waiting for sewage treatment plants to be built in developing countries would require too much time.
