“So describing it as this reciprocal exchange where, like in our own economy, you can get cheetahs you can get fungi that give more than they take or take more than they give. And, you know, like with everything it seems to depend. It depends on the partners involved. It depends on the resources available. You know, and how tough the environmental conditions are, whether this exchange is equitable or not.”

Insight
Hawkins: Mycorrhizal fungi cannot be engineered to draw down additional carbon dioxide
“It's not like we can somehow use mycorrhizae
To additionally now draw down more CO two than they are already.”
Hawkins: Climate efforts should preserve fungal habitats rather than engineer fungi
“I don't think it's so much about it being some kind of carbon reduction system that we can manipulate so much as it's about our behavior change so that we provide conditions that encourage the growth of these mycorrhizal fungi so they can continue to draw down…”
Hawkins: The 13-gigaton fungal carbon pool is just 0.1% of soil carbon
“So I think if you take, you know, all the carbon that is in the soil I did a little calculation a little bit earlier, and we come up with a massive amount, if we express it in CO₂ equivalents, it's nearly
9000.
And our mycorrhizal pool is about 13 gigatons o…”
Hawkins: Mapping fungal diversity provides a crucial tool for carbon offsets
“I think there's a lot of exciting potential there because on the cards are various sorts of maps that we can use in conservation planning. So, you know, when you're planning a conservation area, you will usually look at where you've got high biodiversity. You …”
