The Impact of Diet Changes on Global Warming

For a UK consumer diet change is going to cut your emissions by two to four tons per year of carbon dioxide equivalents as about the same as 13 flights. But in terms of an electric car the estimate is you'd save about two tons of carbon on buying an electric car so it's probably bigger than that. So typically it's difficult to create policy changes for something that isn't visually in front of us today. You know when you look at the issues facing us today long NHS waiting lists or Brexit and how that could affect our daily lives what do you think policy makers need to do particularly when it looks like the changes we need to make are so severe and will probably be very unpopular.
