In the past couple of years there have been big headlines in mainstream publications on how going vegan is the single biggest change we can make to help the environment in terms of greenhouse gas emissions, land and water use. It has a more powerful impact than cutting down on travelling by plane or switching to electrical cars, as animal agriculture and meat production industries produce more greenhouse gases and pollution than the transport industry. But after people make the transition to a plant-based diet, they often start to question if it is environmentally sustainable and what changes they could make to have an even smaller impact on the environment.
Sustainability means preserving the resources we have, using it at an appropriate rate so that each resource can replenish itself naturally, everyone can have enough and there will be a good amount left for future generations. Unfortunately, at the moment there is a disparity between the Western world and developing countries where we are over consuming, over producing and over exploiting resources, leaving very little to people on the other side of the world.
