ENVironmental sustainability


Define the concept of environmental sustainability

 

3 pillars of sustainability

 
Environmental sustainability is defined as meeting the needs of the present without compromising the ability of future generations to meet their needs. This encompasses keeping population densities below the carrying capacity of a region, facilitating the renewal of renewable resources, conserving and establishing priorities for the use of non-renewable resources, and keeping environmental impact below the level required to allow affected systems to recover and continue to evolve.
