Global agriculture is one of humanity’s great success stories, but agricultural production has come at high environmental and social costs. Over the last few decades, many different sustainable agricultural solutions have been developed in response to problems, such as soil degradation, overdrawn and polluted water supplies, biodiversity loss and socio-economic inequities.
Biodiversity at all levels, including the diversity of genes, species and ecosystems, is lost at alarming rates. Critical factors for these trends are habitat destruction, global warming and the uncontrolled spread of alien species. Pollution, nitrogen deposition and shifts in precipitation further affect biodiversity.
FAO's recent report looks into the connections between food wastage and biodiversity and resource loss. Each year, food that's produced but not consumed adds 3.3 billion metric tons of greenhouse gas to the atmosphere and can use significant amounts of water.
