The way we produce, consume and discard food is no longer sustainable. That much is clear from the newly released UN climate change report which warns that we must rethink how we produce our food — and quickly — to avoid the most devastating impacts of global food production, including massive deforestation, staggering biodiversity loss and accelerating climate change.
While it’s not often recognized, the food industry is an enormous driver of climate change, and our current global food system is pushing our natural world to the breaking point. At the press conference releasing the Special Report on Climate Change and Land, report co-chair Eduardo Calvo Buendía stated that “the food system as a whole – which includes food production and processing, transport, retail consumption, loss and waste – is currently responsible for up to a third of our global greenhouse gas emissions.”
In other words, while most of us have been focusing on the energy and transportation sectors in the climate change fight, we cannot ignore the role that our food production has on cutting emissions and curbing climate change. By addressing food waste and emissions from animal agriculture, we can start to tackle this problem. How do we do that?
Livestock production is a leading culprit – driving deforestation, degrading our water quality and increasing air pollution. In fact, animal agriculture has such an enormous impact on the environment that if every American reduced their meat consumption by just 10 percent – about 6 ounces per week – we would save approximately 7.8 trillion gallons of water. That’s more than all the water in Lake Champlain. We’d also save 49 billion pounds of carbon dioxide every year — the equivalent of planting 1 billion carbon-absorbing trees.
