The importance of sustainability is life, both now and in the future. What we do today will, inevitably, affect the future. If we do not make good decisions today, we leave future generations spending most of their time not only cleaning up our messes but we can potentially leave them struggling without their basic needs.
Greed and being wasteful will eventually deplete all of our natural resources. If we continue to misuse and waste our fresh water, our future generations will be without. Other resources will be needed to be used to treat what contaminated water they have left. Without fresh water, fish and other water life that we use for food resources will be depleted; completely polluted, and most likely extinct.
If we continue to pollute our soil, future generations will have a hard time growing other food sources. Our food sources depend on fertile soil and fresh water. If we continue to pollute our world, and greedily waste our precious soil and water, future generations will have no choice but to use some harmful processes for nutrition.
In all actuality, if we continue to pollute and deplete our natural resources, our future generations will not have to worry about it. We, as a human race, will become extinct. Our waters, soils, and other natural resources constantly replenish themselves but if we continue to overuse and pollute, we will diminish the supply and our race will be completely wiped out because of famine and illnesses.
The human population is constantly growing and needing more resources. If we do not realize how to sustain what we have, we will leave future generations without. This is why sustainability is important.
