Other way around. Misinformation about climate impacts leads to poor choices. Replacing your electricity with personally-owned solar, upgrading your vehicle to a high-efficiency hybrid or electric, and lowering your HVAC costs on your home are all far more impactful to your CO2 footprint than changing your diet.
So Oxford Uni and other academic institutes are now spreading misinformation. Ok got it.
And buying solar panels and upgrading to a hybrid or electric car which costs thousands is easier than replacing your meat burger with a plant-based meat burger. Makes total sense and lets ignore biodiversity and habitat loss while we're at it.
Why not do both?
Why not eliminate / reduce consumption of large scale dairy and meat products AND use renewable energy sources?
Surely you would agree doing both is actually even more impactful, no?
