Everyone in Europe consumes too much

If people switched more of their consumption from animal to plant-based food there would be a smaller impact on the environment.

 
A paper in the International Journal of Epidemiology by Phil Edwards and Ian Roberts shows that heavier populations increase emissions for two reasons: they consume more food and they require more energy to transport. A more realistic approach is to persuade people to switch more of their consumption from animal to plant-based food: that way you can eat just as much, with a smaller impact on both the environment and food security. Most people in the rich world carry more weight than they need. Many of those who aren't overweight still consume more calories than they need, but burn them off in the gym. Almost everyone in countries like the UK consumes too much of everything, including food.
