1. Go plant-based
Animal agriculture is responsible for around 18% of human-caused greenhouse gas emissions globally, which is more than all emissions from ships, planes, trucks, cars and all other transport put together.
If you're not ready to commit to a plant-based lifestyle, start small by swapping a few meals to vegetarian or vegan per week, and be more mindful of where your meat comes and how it was farmed.
