OK so I read "Here the key concept is that some of the effects of the large herbivores, such as eradicating trees and shrubs or trampling snow, will result in a stronger cooling of the ground in the winter, leading to less thawing of permafrost during summer and thereby less emission of greenhouse gases".
I know the big impact of trees and shrubs on albedo - in spring they absorb sunlight and shake off snow, which remains on flat grassland. But regarding trampling - compaction- I'm not convinced. Winters are long and summers short, so accelerating cooling by some weeks wouldn't make so much difference, as accelerating warming in the summer - that's when the gases are released.
Anyway what we do urgently need is global science cooperation to try to save the carbon and ecosystems of that permafrost, in that spirit such projects might help to thaw geopolitical obstacles.

Not to mention rejection/loss of their mothers.

So here are some hybrid elephant/mammoths (because take modern elephant egg and replace parts if it with edited dna, keeping most of the modern cell) ; who probably will experience constant pain and unhealthy feelings due to the editing; having life long psychological issues - with no real place to live except in a nature preserve.

The first viable generation will probably be so messed up they need humans to raise the second generation; and the future generations will probably not feel healthy.

Has anyone ever had to deal with several tons of grumpy issues ? I’m fist it’s not me helping

This is why I totally do not support such efforts, done for things other than the new life’s value
