Since the industrial revolution starting in the 1760’s, there has been a massive population increase and humanity has become a global force of change. By pursuing the fundamentals of life, like acquiring necessities such as food and water, humans have inadvertently changed much of the planet. Many of humanity’s actions have gravely disrupted the balance of Earth’s equilibrium; by looking at the environmental impacts of human demands on water, food and energy, we can understand the impacts of human actions. Twenty liters; that is the bare minimum amount of water a person needs for drinking and sanitation everyday. With there being over seven billion of us, it is clear to see the great sum of water we use. But drinking and sanitation do not account for all our water usage; crop irrigation accounts for 70 percent of our usage alone. In addition to usage by thermoelectric power generation, industry, mining and livestock, which all increase human demand on the water system [1]. To supply all this water, humanity has tapped into lakes, rivers, aquifers and the sea. The impacts of these processes can be clearly seen in many cases world wide.
