It is the use of products and services in a way that minimizes the impact on the environment, so that human needs can be met not only in the present but also for future generations. When sustainable consumption is practiced, resources are used wisely and waste products and pollution are minimized.
The main way this is achieved is by doing more and better with less. In other words, we can find ways to meet our needs and desires without depleting our planet's finite natural resources.
This might include carpooling, using renewable energy sources, such as solar or wind power, developing alternative fuel sources, such as biofuels, for our transportation needs and using environmentally friendly cleaning products.
