The recent argument against traveling is a proxy war. Heating, cooling, electricity and driving are the things that make up 75% of the emissions, plus about 20% for industrial production. All of the points I listed can be replaced by sustainable alternatives TODAY (ok, maybe not all people in one year, but the products are available) without us having to reduce out comfort in a major way. We could travel 5 times more…
Really - what solution is there for heating and cooling? Especially given that insulating houses with plastic seems to cause other problems like mold, or pollution with toxins to prevent mold? And driving? People could just stay home, I suppose?
Drive an electric car, and buy renewable electricity.
