The Earth’s total resources are suitable for about 2 billion people at the current demand. With our current global population being 7.2 billion and growing, we’re using 2 to 3 times more of the Earth’s natural resources than what is sustainable (theworldcounts.com).
As you already know, there are alternative sources of energy that can even replace oil, but nothing can substitute potable water. Roughly 70% of fresh water is used in agriculture with another 20% used for industrial purposes. This leaves only 10% of Earth’s supply of fresh water for our consumption (theworldcounts.com). Efficient irrigation systems and proper water management practices help limit the agricultural use of water. Additionally, avoiding the cultivation of water-intensive crops such as maize, cotton, and avocados would further reduce the issue of water scarcity.
With a global increase in urbanization and land cleared for agricultural purposes, an estimated 18 million acres of forests are destroyed each year (theworldcounts.com). As a matter of fact, in the last 40 years, “close to 20 percent of the Amazon rain forest has been cut down-more than in all the previous 450 years since European colonization began” (http://environment.nationalgeographic.com/). Below are just a couple facts about how dire this situation has become:
-According to FF Conserve Energy Future, it is estimated that there will be no rainforests within the next 100 years.
-1.6 billion people depend on forest products for their livelihoods.
-Soil erosion, floods, wildlife extinction, and climate imbalances are all effects of deforestation (http://www.conserve-energy-future.com/).
Fortunately, there are a number of organizations that battle against deforestation by taking political actions to ensure fair enforcement of forest conservation laws. For more information on how you can help, please visit greenpeace.org.
