Unsustainable living...for whom does it apply?

In the presentation from last class, the issues of clean drinking water became the main topic for discussion in regards to countries such as India and Africa. When corporations are coming into these regions and depleting their water sources and eliminating some of them all together, we begin to wonder how they are doing this? Who has the right to prevent a resource that everyone has an equal right to, such as water? That is what I feel is the main argument in this water crisis and the unsustainable living it produces.
No one in my opinion should have the right to OWN water, who is to say that water is theirs and they can prevent millions of people from drinkable water in order to better their company and spread their markets. Companies like Coke, which were referred to in the film from class, have taken this exploitation method of creating their product. Water is taken from villages in India and replaced with unsanitary and undrinkable water for the rest of the community. Fresh water that used to be available is now used in creating coke products in factories across India.
There need to tighter regulation across boarders, which make it illegal to exploit such people in their attempt to live healthy life. Water is a necessity and these communities are being deprived of their right to a sustainable life. These issues would never arise in the developed world, as we have the power to create sustainable lives and adequate access to life resources. So why does this happen in other parts of the world? Just because we are not seeing the effects of our own corporations on other nations, why does this make it alright?
The new solar water filters implemented in parts of India was a smart and successful idea in the aim for a solution. There are other solutions like the life straw and other nations need to catch on to this! and soon!
