Ban the beef?
For many environmental campaigners, eating meat is fast becoming as repellant as smoking – behavior to be discouraged or even banned. But is your hamburger really to blame for climate change, and would going vegetarian really help?
In a developed-country setting, the reality is that going entirely vegetarian for the rest of your life means reducing your emissions by about 2 percent. Instead of banning meat eaters from restaurants, we need more R&D to reduce the carbon impact of farming, as well as to develop and produce at scale artificial meat, which could cut greenhouse-gas emissions by up to 96 percent, relative to conventionally produced meat.
