Yes, they do. The issues of why that’s not a solution are complicated, but I’ll touch on a few. Let’s just say that we should absolutely be reforesting with multi-species forests everywhere we’ve taken away, but mostly to try and bring back some biodiversity we’re killed, if possible. As a carbon sink plants of any sort, even fast-growing algae, have their limits, and we can’t possibly plant enough to offset the millions of years of plant growth we’ve put into the air via fossil fuels. I can’t speak for Australian land, who owns it, what it’s used for or how arable it is for lots of trees.

So let’s renew what we’ve taken, but for other reasons not the falsehood that it’s a viable large-scale carbon sink.
