Reading: Sustainable foods
The food we eat
One way to cut down your personal carbon footprint is to stop eating meat and, if possible, dairy products, or at least reduce them. Cattle farming uses up to 100 times more land than growing protein-giving crops and we now know that legumes like beans and lentils can provide the necessary protein. You also need a good variety of vegetables and to add nuts, seeds to recipes. If you can't eliminate meat entirely, go for the environmentally friendly kind like organic meat. New ways of producing cell-cultured meat, fish and cheese alternatives are currently being developed. Pesticides and herbicides interfere with natural ecosystems and tend to reduce biodiversity. Organic foods are much better, but often cost more. It also seems that fish is less beneficial for the heart than we previously thought and much of it comes from non-sustainable sources. Finally, many people are already switching to plant-based milk, and we know that dairy farming is a huge cause of global heating. However, some non-dairy alternatives may need a lot of water to make and others such as soy and oat milks can be highly processed.
A: Some types of animal raising
B: It's better to eat meat
C: There are now new ways to create
D: Some substitute products
E: The author suggests
F: Environmentally friendly food
