Do it against food waste! Only buy as much food from the buffet as you actually eat!

Uneaten food is destroyed, releasing a number of environmentally harmful gases, including methane, into the air. Research shows that climate change is largely due to the destruction of uneaten food. We produce around 88 million tonnes of food waste in the European Union every year. That's a lot. That is, if we only take as much in front of us in a restaurant meal as we really eat, we can do a lot against the negative effects of climate change.
