Technically.

+ Instead of hunting on the seas we should perform aquaculture. Establish diets that can use sea vegetables. Create methods to harvest on sea. This can reduce CO2 in the oceans and reduces the burden on land.

+ Accelerating research into reducing the CO2 footprint of our food. Lab grown meat and fish needs to be on wafer scales.

+ Create market places that reduces friction between CO2 producers and CO2 reducers. Make it easier to share solar panels or to share roofs. Make it easier to provide clean energy to Indian or Chinese households. Make it easier to find locations for wind mills. All these things can be accelerated through digital communication.
