If destroyed or degraded, the Amazon, as a system, is simply beyond humanity’s ability to get back: Even if people were to replant half a continent’s worth of trees, the diversity of creatures across Amazonia, once lost, will not be replenished...

Can someone elaborate on this? I thought all that matters for carbon balance is biomass, and vast majority of this comes from trees, so diversity doesn't matter as long as there is enough trees.
