Some things don't make sense anymore. Time to change them. Time for new standards.
As a futurist and speaker I've been speaking about sustainability for over 15 years. We have the consciousness, the technologies and alternatives to change. Now we need social change and new standards. We could stop smoking on planes, we can stop eating meat on planes and thus save tons of meat and CO2.
The global aviation industry produces around 2.1% of all human-induced carbon dioxide (CO2) emissions.
UN's Food and Agricultural Organization has said about 14.5% of all emissions come from meat and diary production.
