Moreover, in developed countries where the 'veganism will solve the problem' argument is most frequently made, animal agriculture is responsible for an even smaller share of the global warming problem than fossil fuels.
For example, in the USA, fossil fuels are responsible for over 10 times more human-caused greenhouse gas emissions than animal agriculture.
That's not to minimize the significant global warming impact of animal agriculture (as well as its other adverse environmental impacts), especially from beef and lamb, but it's also important not to exaggerate its contribution or minimize the much larger contribution of fossil fuels.
So, animal agriculture and meat consumption are significant contributors to global warming, but far less so than fossil fuel combustion.

Moreover, fossil fuels are an even bigger contributor to the problem in developed countries, which use more energy and have increased livestock production efficiency (Pitesky et al. 2009).
For example, in the United States, fossil fuel-based energy is responsible for about 80% of total greenhouse gasemissions as compared to about 6% from animal agriculture (estimates from the World Resources Institute and Pitesky et al. 2009).
