People still aren't going to change their lives at a high enough rates to have an effect on the economy. We aren't moral like that without some huge event with clear and obvious damage to make a significant impact on culture.

Subsidies for farms aren't ending anytime soon, and people are so used to and happy to continue eating meat that I can't see things changing in the future near enough to actually have an impact on climate change.

What we need is a continued push for green technology and efficient use of resources, not for people to cut back on/change their lifestyles. It takes the CFL bulb and easy-to-install, cheap, insulation to reduce electricity usage, not people turning their lights off.

The problem with global warming at the end of the day is net emissions of CO2 into the atmosphere. Make the fertilizer needed without fossil fuels, make our use of land more efficient, and the net emissions in the long term from cows is not going to be significant. We should focus on doing those things, not trying to convince people to stop eating meat.
