Americans waste 150,000 tons of food each day – equal to a pound per person


Research shows people with healthy diets rich in fruit and vegetables are the most wasteful and calls for better education for consumers

About 150,000 tons of food is tossed out in US households each day, equivalent to about a third of the daily calories that each American consumes. Fruit and vegetables were the most likely to be thrown out, followed by dairy and then meat.

This waste has an environmental toll, with the volume of discarded food equivalent to the yearly use of 30m acres of land, 780m pounds of pesticide and 4.2tn gallons of irrigated water. Rotting food also clogs up landfills and releases methane, a powerful greenhouse gas.

Researchers at the US Department of Agriculture analysed eight years of food data, up to 2014, to see where food is wasted and also what members of the public say they do at mealtimes. The research has been published in Plos One.

 

Ride shotgun on this game-changing farm in “One Hundred Thousand Beating Hearts,” streaming now on Salon Premium

Will Harris, a good ol’ boy Georgia rancher, may well be our nation’s best bet for a better, more sustainable future. He’s the subject of a documentary by Peter Byck, “One Hundred Thousand Beating Hearts.”

Tell us one story about the production.

When Will was taking me around the surrounding counties, to see the dying towns, small towns that had a strong agricultural base and that had been shriveling up due to poor economics for the local folks, we were filming along an old mill and rain was impending. I could see the coming squall down the road and it appeared to me to be about four minutes away. At about three minutes [out], when Will finished his answer to one of my questions, I grabbed the camera and tripod, told him we’d better run back to his truck, and as soon as we shut the doors, it started to really come down. He was impressed with my sense to read the rain. That made me feel good.

What’s been your past interest in sustainable animal agriculture?

I look to regenerative agriculture, and AMP [adaptive multi-paddock] grazing in specific, as a potential way to draw down significant amounts of carbon from the air and store it in the soils. Carbon is the currency for healthy soils — and healthy soils produce healthy foods and help farmers to make more food on their land. My experience is filming farmers and ranchers across the U.S., Canada and the UK. These innovative producers of food are my heroes.

General Mills is transitioning 53 square miles of South Dakota farmland to certified organic.

This headline from the smart website newfoodeconomy.org caught our attention: “General Mills is transitioning 53 square miles of South Dakota farmland to certified organic.” That’s 34,000 acres that will be converted to organic by planting a mix of hard red spring wheat (for pasta) hard red winter wheat, dry yellow peas, corn, soybeans, sunflowers and alfalfa. They call it Project Gunsmoke.

“The Gunsmoke project is an opportunity to use our scale to help convert large areas of acreage to organic as one of our tools to create a more stable supply chain,” General Mills said.

In short, demand for organic, or chemical-free, foods is growing exponentially and the major food suppliers can’t keep up.

Seabird poop warms the Earth, and cools it

Three new studies of how the world works show that seabird excrement plays an unexpected role, as do polar algae and rotting trees.

 

Three new studies of how the world works show that seabird excrement plays an unexpected role, as do polar algae and rotting trees.

 The world’s seabirds don’t just live off the land, they also nourish it: their excrement delivers 591,000 tons of nitrogen and 99,000 tons of phosphorus to feed plant communities in the soil and the water.

One polar plant community that happens to be flourishing is now to be found on the surface of Greenland’s icecap: green things are growing so well they are darkening the surface, which then reflects less light and absorbs more warmth. This algal darkening could be responsible for at least 5%, and possibly 10%, of the island’s total ice melt each summer.

And although the Arctic tundra wetlands are known to deliver between 16 and 27 million tons of methane to the atmosphere every year, they have unexpected competition in the natural greenhouse gas emission stakes.

A eureka moment for the planet: we’re finally planting trees again

After centuries of bad stewardship, communities are at last starting to see the benefits of forests.

China plans to plant forests the size of Ireland. Latin American countries have pledged to restore 20m hectares of degraded forest and African countries more than 100m hectares. India is to plant 13m hectares, and on a single day last year 1.5 million people planted 66m trees in Madhya Pradesh alone.

Much of Europe is physically greener than it was just a few years ago. England is to plant 50m trees in a new coast-to-coast forest and newly planted saplings now cover tens of thousands of hectares of former farmland in Ireland, Norway and France. From Costa Rica to Nepal and Peru to Mongolia, tree planting has become a political, economic and ecological cause, and a universal symbol of restoration, regrowth and faith in the future. More than 120 countries promised in 2015 to plant and restore large areas of forest as a response to the climate crisis, and the UN has set a target to restore 350m hectares by 2030 – an area bigger than India.
