They have demonstrated that in its pristine state − mangrove swamps, wetlands, savannahs, forests and so on − nature left alone is of more value to humankind than as exploited real estate.

UN survival plan offers new hope for the planet
This argument has been made already, and more than once. But this time the researchers can provide the detail for their argument: they report in the journal Nature Sustainability that they had devised an accounting methodology to test such arguments, and then applied this in 24 selected sites around the planet.
Some of the value would be in intangibles such as providing a shelter for the wild things and wild plants; some of it would be measurable.
For instance, if the damage inherent in carbon spilled into the atmosphere through habitat destruction or fossil fuel combustion presents an overall cost to society of $31 a tonne − and this is a conservative estimate − then almost three quarters of the sample sites have greater value simply as natural habitats.
And that includes 100 per cent of all forests. If that greenhouse gas carbon was valued at a paltry $5 a tonne, almost two thirds of the sites would still be, over a 50-year period, a better investment left untouched.
