> We increased crop yields multifold already

With catastrophic effects.

Agriculture production as a major driver of the Earth system exceeding planetary boundaries

Most of it is because of animal agriculture - it uses 80% of agriculture land and about half of our crops.

> Could we breed trees which capture more CO2?

We don't have to breed new trees. The ones we have are enough.

We have enough space to capture 2+x more CO2 than we've released into the atmosphere since industrial revolution.

We could switch to plant-based diets and free an area the size of both Americas.

On that land a regular primeval forest, Miyawayki/Amazon/Syntropic style would grow 10x faster than regular monocultures and that would also enable the biodiversity to rebound. We'd get ourselves out of overshoot in no time (given few decades, of course).

The overshoot threatens our civilization with crop failures. The only realistic way out of it is immediate phase-out of fossil fuels and plant-based diets.
