The world has two years to secure a deal for nature to halt a ‘silent killer’ as dangerous as climate change, says biodiversity chief. The world must thrash out a new deal for nature in the next two years or humanity could be the first species to document our own extinction, warns the United Nation’s biodiversity chief.
Ahead of a key international conference to discuss the collapse of ecosystems, Cristiana Pașca Palmer said people in all countries need to put pressure on their governments to draw up ambitious global targets by 2020 to protect the insects, birds, plants, and mammals that are vital for global food production, clean water, and carbon sequestration. “The loss of biodiversity is a silent killer,”. “It’s different from climate change, where people feel the impact in everyday life. With biodiversity, it is not so clear but by the time you feel what is happening, it may be too late.”
The world body responsible for maintaining the natural life support systems on which humanity depends. Conservationists are desperate for a biodiversity accord that will carry the same weight as the Paris climate agreement. But so far, this subject has received miserably little attention even though many scientists say it poses at least an equal threat to humanity.
Eight years ago, under the Aichi Biodiversity Targets, nations promised to at least halve the loss of natural habitats, ensure sustainable fishing in all waters, and expand nature reserves from 10% to 17% of the world’s land by 2020. But many nations have fallen behind, and those that have created more protected areas have done little to police them. “Paper reserves” can now be found from Brazil to China.
Pașca Palmer says there are glimmers of hope. Several species in Africa and Asia have recovered (though most are in decline) and forest cover in Asia has increased by 2.5% (though it has decreased elsewhere at a faster rate). Marine protected areas have also widened. But overall, the picture is worrying. The already high rates of biodiversity loss from habitat destruction, chemical pollution, and invasive species will accelerate in the coming 30 years as a result of climate change and growing human populations. By 2050, Africa is expected to lose 50% of its birds and mammals, and Asian fisheries to completely collapse. The loss of plants and sea life will reduce the Earth’s ability to absorb carbon, creating a vicious cycle. Despite the weak government response to such an existential threat, “the infrastructure of life” was undimmed.
One cause for hope was a convergence of scientific concerns and growing interest from the business community. Last month, the UN’s top climate and biodiversity institutions and scientists held their first joint meeting. They found that nature-based solutions – such as forest protection, tree planting, land restoration, and soil management – could provide up to a third of the carbon absorption needed to keep global warming within the Paris agreement parameters. In future, the two UN arms of climate and biodiversity should issue joint assessments. Although politics in some countries were moving in the wrong direction, there were also positive developments such as French president, Emmanuel Macron, recently being the first world leader to note that the climate issue cannot be solved without a halt in biodiversity loss. This will be on the agenda of the next G7 summit in France.
“Things are moving. There is a lot of goodwill. “We should be aware of the dangers but not paralyzed by inaction. It’s still in our hands but the window for action is narrowing. We need higher levels of political and citizen will to support nature.”
