After reading/listening to the TED talk I am feeling like something is missing: what we,as a society, can do about that? I don't see any offers there except "Stop wasting food". Are there any movements that help with it? I know there is a cool app/movement in the EU called "Too Good To Go", I would love to have something like that in the US. I personally don't mind consuming food even if it expires according to the date on it because most products are still good after the expiration date. 

As I mentioned in my other annotation, money is the reason. When consumers have money producers will try to sell products. For example, the company in South America makes 1000 bananas per year and it can be sold to the USA for 50c/pound or to different countries for 25c/pound. Of course the US is the way to go, even if half of bananas will be wasted that still will make the same profit. Then it comes to the transportation company: the company in the US offers 10000$ to transport goods to them, while the other country will offer much less. All roads used to lead to Rome, now all roads lead to the US/other developed countries.

Money is the reason. Those people who produce, transport and store food are doing their job and I think they have all rights to expect money for it, but to stop wasting they need to do more work. So, who will pay  them? 

That's an important point, even though we can't do a lot on our own, but we need to try to create a pressure on people who actually have enough power to change the world significantly.

Our society built in the wrong way from beginning and now we have to rebuilt it. It's like an ancient city where everything is old and needs to be fixed, so it much easier just to build another one instead. For examples nuclear weapon: it costs a lot and all those money might go to education, healthcare etc., that thing went wrong from the point it was developed. This was just an example, there are many more of such things. But the problem is that we can't rebuild society.

The problem is that not everyone wants it same way as others. There are some egoistical people who want to take more advantage than others, and the biggest problem is that those people have more power than we do.
