"Wood Wide Web: Scientists to map hotspots of fungal life" A science mission is set to explore one of the final frontiers of untapped knowledge on the planet - the fungal networks in the soil beneath us.
Fungi form an underground network of connections with plant roots, helping to recycle nutrients and to lock up planet-warming CO2 in the soil.
But little is known about this giant mesh of fungi and its role in fighting climate change.
It is part of what's popularly known as the Wood Wide Web.
This is an underground network of plant roots and fungi that, among other things, allows trees to share nutrients.
And scientists say "underground conservation" has been long overlooked.
The initiative to map and preserve the Earth's underground fungal networks is led by the Society for the Protection of Underground Networks.
It is the start of an "underground climate movement" to protect "this ancient life support system" said Toby Kiers, professor of evolutionary biology at VU University in Amsterdam.
Scientists say fungal networks are under threat due to agricultural expansion, the use of fertilisers and pesticides, deforestation and urbanisation.

"More work needed to create green jobs, report says" What is a green job?
The simplest answer is a job that directly contributes to tackling climate change, although many think it should also cover roles that indirectly support that ambition.
Growing sectors where one might find more green jobs being advertised include low-carbon farming, heating without emissions, and wind turbine maintenance.
In its research, PwC said jobs that support the green economy indirectly should also be considered green.
Such roles might include environmental advisers or experts in environmental or sustainability research and education.

Economic rebalance
PwC's report said work was needed to ensure the move to a net-zero economy does not add to regional inequalities.
It found that Wales, Northern Ireland and Yorkshire and the Humber lagged behind other parts of the UK in terms of transitioning to a greener economy. Scotland and London were the top performers, according to the research.
PwC ranked areas in terms of how they performed in job creation, the benefits of green jobs, the loss of "sunset jobs", the carbon intensity of employment, and green workplaces.
They hunted for online job ads that mentioned things like sustainability and environment - there had to be a number of mentions.
