My favorite carbon-capture solution is to breed whales: https://www.imf.org/external/pubs/ft/fandd/2019/12/natures-solution-to-climate-change-chami.htm https://www.imf.org/external/pubs/ft/fandd/2019/12/natures-s... Whales act as a nutrient pump in the ocean; beside the 30-tons of carbon they capture and sink over their lifetime in their own biomass, they eat in the deepest parts of the ocean and come back to the surface to breathe, where they release a large amount of nitrate, phosphorus and iron every time they defecate, causing a lot of algal growth. restoring whales population to their pre-industrial levels could have the same effect as planting several billion trees.

> restoring whales population to their pre-industrial levels could have the same effect as planting several billion trees. I would like to see the maths on that :D Whales usually don't create their own microclimate or provide a habit for a number of species. They also don't rebuild and support topsoil, can't be harvested for fibres and are not very suitable as building materials. In other words, trees are more versatile than whales.

  Ideally we would have more of both trees and whales as part of a comprehensive approach to climate change mitigation.
