The Guardian has a conservative (in the original sense) take on our biggest ecological challenge, with a science-based campaign to fight climate change by restoring forests, beaches, and other wild spaces:
“We are championing a thrilling but neglected approach to averting climate chaos while defending the living world: natural climate solutions. Defending the living world and defending the climate are, in many cases, one and the same.”
The signatories include the school strikes activist Greta Thunberg, the climate scientist Prof Michael Mann, the writers Margaret Atwood, Naomi Klein and Philip Pullman and the campaigners Bill McKibben and Hugh Fearnley-Whittingstall.
Rowan Williams, the former archbishop of Canterbury, Mohamed Nasheed, the former president of the Maldives, and the musician Brian Eno are also among the signatories of the letter, which was instigated by the Guardian writer George Monbiot.
The group emphasises that natural climate solutions are not an alternative to the rapid decarbonisation of energy, transport and farming. Both are needed, the campaigners say.
…
Recent research indicates that about a third of the greenhouse gas reductions needed by 2030 can be provided by the restoration of natural habitats, but such solutions have attracted just 2.5% of the funding for tackling emissions.
The greatest impact is likely to come from the restoration of forests, particularly areas in the tropics that were razed for cattle ranching, palm oil plantations and timber. But natural climate solutions must not compete with the need to feed the world’s growing population, the letter says, and must be implemented with the consent of local communities.
Effective ways of restoring habitat often overlap with the conservation of wildlife, the group says. Boosting the populations of forest elephants and rhinos in Africa and Asia would help spread the seeds of trees that have a high carbon content, for example, while more wolves would lead to fewer plants being eaten by moose.
The fastest accumulation of carbon occurs in vegetated coastal habitats such as mangroves, saltmarshes and seagrass beds, research shows, which also protect communities from storms. Here, carbon can be sequestered 40 times faster than in tropical forests. Peatlands must also be protected and restored, the group says, as they store one-third of all soil carbon despite covering just 3% of the world’s land.
