The global food waste scandal

Western countries throw out nearly half of their food, not because it's inedible -- but because it doesn't look appealing. Tristram Stuart delves into the shocking data of wasted food, calling for a more responsible use of global resources.

Seth Dixon's curator insight, February 14, 2017 2:57 PM

No one should be surprised that more developed societies are more wasteful societies.  It is not just personal wasting of food at the house and restaurants that are the problem.  Perfectly edible food is thrown out due to size (smaller than standards but perfectly normal), cosmetics (Bananas that are shaped 'funny') and costumer preference (discarded bread crust).  This is an intriguing perceptive on our consumptive culture, but it also is helpful in framing issues such as sustainability and human and environmental interactions in a technologically advanced societies that are often removed form the land where the food they eat originates.

My scoop it opinion piece was on global food waste. How globally food is thrown by the tons daily. Its audience is everyone and its purpose is to try to get people to open their eyes and waste less. America makes over four times the amount needed to feed its people. We are hurting the environment by making so much food that just go to waste. The purpose of this is to illustrate the huge issue we have with countries of people who don’t have food to begin with and here we are throwing away perfectly good food that could be use for these people or to feed pigs to make more meat. His exigence is all the food that could be use for other people or animals and its going to land fills daily. Its like a ticking time bomb hurting earth. His constraints are the laws set on food given to live stock in Europe and companies and the corporations that control the food. He urges people to use the amount of food they truly believe they will eat.

I've linked galleries of the artistic, aerial photography of Yann Arthus-Bertrand several times before.  In this Ted Talk, you can hear what motivates his artistic vision and the global perspectives that he wants to bring to the fore.  You can also watch the 90-minute video 'Home' that he discusses in the talk here.

This TED-ED lesson was produced in part by an AP Human Geography teacher and the strands of geographic thought in this video are evident.  More geographers should make their own TED ED lessons; thanks for blazing the trail Shannon!

Great video! Very cool to see how far the world has come in regards to globalization. Technology has allowed the people across the globe to immerse themselves in other cultures and good from other parts of the world.
