and this is where thearbon is. what's interesting about this, they made this field, this is new, so they're helping to sequester carbon. living soils like this retain on average three times more carbon than the foliage above the ground. if we were to restore the vast areas of the planet where we humans have degraded the soils, just think what an impact we would have in taking carbon out of the atmosphere. as much as a quarter of the world's land mass has been degraded. and much could be rehabilitated in the way we have seen on the loess plateau. and we've only just begun to recognize the real value of natural capital. surely, investing in the recovery of damaged environments is a cost-effective way of solving many of the problems we face today. >> why do we not invest an equal amount, if not more, into a shovel-ready technology, so to speak, which is nature's way of sequestering and storing carbon? it is actually by investing in our ecological infrastructure and ecosystems, and expanding the ability of nature to se
