Sustainability
Sustainability according to the Environmental Protection Agency (EPA) is the goal "to create and maintain conditions under which humans and nature can exist in productive harmony, that permit fulfilling the social, economic and other requirements of present and future generations." In simple terms, the effort to use finite resources efficiently while being conscious of the consequences of overusing them with regard for the future.
To understand this concept more clearly, sustainability has been broken down into three main pillars of focus: Economy, Environment and Society. These pillars help to break up the vast interconnected areas of sustainability which each require certain amounts of attention at various levels.
The three pillars of sustainability each contain six broad topics that relate to its respective pillar. The purpose of showing these is to provide understanding of the interactions between the environmental, social, and economic pillars in order to fully comprehend the consequences and reality of our actions. Seeking sustainable solutions in these pillars and topics allows us to simultaneously protect and give the right attention to the environment while also making our communities and economy better.
Environment: Ecosystem services, Green Engineering and Chemistry, Air Quality, Water Quality, Stressors and Resource Integrity
Social: Environmental Justice, Human Health, Participation, Education, Resource Security and Sustainable Communities
Economy: Jobs, Incentives, Supply and Demand, Natural Resource Accounting, Costs and Prices

Why Sustainability?
Food
About one third of all food produced -roughly 1.3 billion tonnes worth around $1 trillion - ends up rotting in bins or spoiling spoiling due to poor transportation and harvesting practices
Energy
Natural Resources
Should the global population reach 9.6 billion by 2050, the equivalent of almost three planets could be required to provide the natural resources needed to sustain current lifestyles
