Sustainability is important for many different reasons. First of all, many of the resources we use come from a finite supply. Practicing sustainability can help ensure that these resources last longer and do not disappear. Furthermore, the earth provides several services to the surrounding environment that positively affect our lives. Without these services, which are at risk due to  unsustainable practices, we may face greater challenges such as increased flooding and water pollution. Taking a look at how we use our monetary resources can also contribute to sustainability by ensuring that the economy continues to prosper. Last but not least, sustainability provides important visions to how we can obtain social justice.
