I have been a strong supporter of zero waste attitude all my life. I feel sick when I see how food is wasted. People in Africa are underfed while rich Europe throws away millions of tons of food every year. I read some fun statistics which in fact are saddening - e.g, producing one hamburger requires a few hundred litres of water. Incredible.
At home we discard food only when it got mouldy - all surplus food and leftovers which aren`t consumed for 2, 3 days land in the freezer for later consumption.
Slowly the awareness is rising. Also in Poland. The food sharing boxes are placed in biggest cities. Politicians, especially leftist, promote using them.
