I recently read David Attenborough’s 2020 book, “A life on our planet: My witness statement and a vision for the future”. Ever since, I have been contemplating how on earth it will be possible to action the plans he outlines for preserving functional global climate systems, biodiversity, and saving ourselves from ourselves.

Rewilding is one solution Attenborough envisages. A small example may be when many urban neighbourhoods develop their own small forests and foster biolinks. The cumulative effect could be significant. Just as each relatively small piece of new built environment and mono cultural agribusiness diminishes our capacity to recover, each relatively small piece of new ecosytem and forest enhances it.
