Professor Sonia Seneviratne:

I am not an economist and these are just my thoughts. Global solutions need to be found. If there was some type of CO2 tax, the meat that is produced at the same time, which leads to higher CO2 emissions, would be more expensive and, therefore, it could be one way to solve the issue. As always, it is an interconnected problem. I do not know if it is realistic to have a global CO2 tax.
