Wondering what you're going to do with all your Thanksgiving leftovers? Anti-waste food movements will prompt you to use every last bit.

There is a global campaign to reduce food waste in order to aid the environment and economy. You may have seen the pictures the Chinese have been posting all over social media of their spotless plate. In South Korea, waste companies have started charging by weight in an effort to persuade families to waste less food. Here in the U.S., states are banning kitchen waste from being sent to landfills.

The center of this anti-waste food movement is London. Countless pop-up businesses have emerged with a goal to reduce food waste. London has more of these enterprises than any other city in the world. Technology is a major player in London's efforts to eliminate food waste. Whether it is connecting charities to local restaurants and markets with extra food or uploading a picture of your leftovers to an app for others to find, technology is making this surplus of food more accessible than ever before.

So why is it so important to limit food waste? Food waste is a pretty big economic burden for families around the world. There are also many environmental issues caused by food waste due to inefficient use of various resources. The United Nations estimates that about 1/3 of the world's food is never consumed. This amounts to around 1.3 billion tons of waste a year. For the United States specifically, Americans waste around 40 percent of all food produced.

With the world's population growing every year, addressing the issue of food waste could be the solution to more than one problem. In cities where most of the world's population lives, these start up companies could shrink the giant socioeconomic gap found in most urban areas. Time and time again, it has been proven that there is enough food on our planet to feed everyone. Hopefully there is a way to expand this movement to other regions and help to end hunger world wide.
