Whether you eat meat and fish or you are a staunch vegan, every food choice you make has an impact on the wider world.
The production of meat and dairy products in particular has a high environmental impact, in terms of its consumption of land, water, energy and other key resources. Eating less of both is a no-brainer if we want to eat more sustainability, and is probably healthier for us too.
Radically changing what we eat is easier said than done, however. How to persuade people to change their diet, and how to produce food more sustainably, remain contentious issues.
