Today is World Environment Day and this year’s event is focused on cutting the world’s staggering amount of food waste. “Think. Eat. Save. Reduce your Foodprint“ is the motto of the global event which is being marked by marches, awareness-raising campaigns, talks, marathons and other events around the globe.

And the statistics published by the United Nations might just give you food for thought. According to the UN Food and Agricultural Organization (FAO), an estimated one third, or 1.3 billion tons, of all food produced worldwide ends up in the trash. Farmers, transporters, retailers and consumers alike are to blame for the waste.

The FAO says this isn’t just a colossal waste of food but also a squandering of natural resources used along the production and supply chain process. The FAO is urging people to be more aware of the decisions they make regarding food consumption.

And if that isn’t enough to make you pause and think, consider this – the FAO says that to produce one single hamburger, 16,000 liters of water are used.

And here’s another chilling fact for all the meat-lovers out there – the FAO estimates that producing one kilogram of meat is far worse for the environment than a 250-kilometer-long car drive. That takes into account the massive cost of feeding animals.  It’s estimated that up to 35 percent of grain harvests around the world and 80 percent of soya harvests are used as animal feed.

At the same time, 870 million people around the world go hungry every day.
