Fresh Water, H2O, one of Earth's most valuable natural resources.
Some problems associated with water of the future is the climate is warming, and many places (such as the Amazon) may very well be at high risk.

What can YOU do to help reduce the stresses on our waters? Long term solutions rely on technological achievements like being able to cleanse ocean salt water into fresh water very ECONOMICALLY, making the switch to renewables, and making meat more ecologically sustainable.

Meat as we know has a very high environmental footprint...

This 3d link will give you the environmental footprint of cattle. [link]

Growing meat with stemcells extracted from livestocks (if done properly) could reduce the environmental impacts, since it takes a lot of resources to feed the cattle/livestocks and take care of them. [link]

But many of the technologies which will provide long term solution are a few years of not decades from now...
So back to our question WHAT CAN WE DO now?

1)I am not telling you to become a vegetarian, however reducing how much meat we eat would help lesson the environmental strains. I have reduced the amount of meat I have taken in compared to last year.
2)Making showers a little bit shorter (very difficult for me) would help.
