THE COMMODITY ISSUE Youth Strike for Climate protests in London, UK Photo Nuala O’Leary t our Cambridge office in the UK, the endless news coverage of Brexit is finally giving way to something different. In recent months, headlines have reported Extinction Rebellion protesters blocking the streets of London, Sir David Attenborough explaining the science behind climate change on prime-time television, and 16-year old climate activist Greta Thunberg meeting with party leaders in Parliament. Across the world, civil society has similarly mobilised: school children are going on ‘climate strike’ in 30 countries, Extinction Rebellion protests have spread from South Africa to Hong Kong to Australia, and indigenous people are gathering to demand environmental protection for their territories in Brazil. A To some, such protests are little more than an irritation or distraction from ‘business as usual’. But a hard-hitting new global report backs up the protesters’ actions with solid fact. Drawn from 15,000 scientific and government sources, and compiled by nearly 150 expert authors from 50 countries over three years, it shows that ‘business as usual’ is no longer an option. What makes this report special is that it is not an assessment compiled by the science world and then submitted to the government. On the contrary, it has in fact been endorsed and adopted by the governments themselves, as members of the United Nations Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES). In May, the panel attended a week-long meeting in JUL-SEP 2019 • BIRDLIFE Paris to fine-tune the report before publication. As one of the key contributors to the report, BirdLife was in the midst of the action. The messages of the IPBES global assessment, when it was released, were hard to ignore: nature is declining at a rate unprecedented in human history. One in four species assessed by the IUCN Red List is threatened with extinction – which works out as a possible one million species we may lose within our lifetimes. Even species that are not yet threatened have suffered substantial declines in abundance. Vertebrate species have on average seen a 60% drop in numbers since 1970. The habitats that these species depend on are also being lost: overall, 75% of the planet’s land area and 40% of its marine area is severely altered by human impact. The loss of species, genes and habitats is not just of concern to academics and conservationists, but to us all. A healthy ecosystem is one that has both variety and abundance of life, and it is this delicate balance that delivers what are known as ‘ecosystem services’ such as pollination, water purification and carbon storage. These in turn provide us with the food, water and clean air we need to live. The more biodiverse an ecosystem, the greater the benefits and the more likely that it will be resilient to change – including climate change – in the long term. In short, the loss of biodiversity is destroying our life-support system: a threat just as urgent as the now-famous ‘1.5-degree’ climate change 13
