Francis Vergunst, Julian Savulescu:
When we hear about the horrors of industrial livestock farming – the pollution, the waste, the miserable lives of billions of animals – it is hard not to feel a twinge of guilt and conclude that we should eat less meat.
Yet most of us probably won’t. Instead, we will mumble something about meat being tasty, that “everyone” eats it, and that we only buy “grass fed” beef.
Over the next year, more than 50 billion land animals will be slaughtered for food around the world. Most of them will be reared in conditions that cause them to suffer unnecessarily while also harming people and the environment in significant ways.
This raises serious ethical problems. We’ve compiled a list of arguments against eating meat to help you decide for yourself what to put on your plate.
1. The environmental impact is huge
Livestock farming has a vast environmental footprint. It contributes to land and water degradation, biodiversity loss, acid rain, coral reef degeneration and deforestation.
Nowhere is this impact more apparent than climate change – livestock farming contributes 18% of human produced greenhouse gas emissions worldwide. This is more than all emissions from ships, planes, trucks, cars and all other transport put together.
Climate change alone poses multiple risks to health and well-being through increased risk of extreme weather events – such as floods, droughts and heatwaves – and has been described as the greatest threat to human health in the 21st century.
Reducing consumption of animal products is essential if we are to meet global greenhouse gas emissions reduction targets – which are necessary to mitigate the worst effects of climate change.
