The best negative carbon tech that exists are trees and plants. It's not future tech it's already here!

Yes. However it only works when trees grow and are not burnt after (use in construction for example). I will try to find sources if you're interested but basically this solution (planting forest & not burning wood) does not scale. You'd have to cover very large areas with trees (losing land for agriculture btw). To push it further as the amount of land is limited this can't work with a scenario of growing emissions. It's clearly interesting to mitigate the problem though.

We don't need to scale up if the developed countries agree to scale down consumption. Reducing commuting (working from home when possible), have taxes on airplane travel, tax goods that come unnecessarily from far away, invest in durability. This is not scyfy solutions sorry to disappoint

Wetlands and algae or pond plants are even more effective than trees.

Though yes, generally, biological carbon fixation is highly effective.

australia made the news about billion trees project, I wonder how many similar ideas are being rolled out
