The “alarming” rate at which species are being lost could have a severe effect on humanity, conservationists warned on Monday. Targets set eight years ago by governments to reduce biodiversity loss by this year have not been met, experts confirmed at a UN meeting in Nairobi, Kenya.
The third Global Biodiversity Outlook report said loss of wildlife and habitats could harm food sources and industry, and exacerbate climate change through rising emissions.
Achim Steiner, the executive director of the UN Environment Program (UNEP), said: “Humanity has fabricated the illusion that somehow we can get by without biodiversity or that it is somehow peripheral to our contemporary world: The truth is we need it more than ever on a planet of 6 billion [people], heading to over 9 billion by 2050. Business as usual is no longer an option if we are to avoid irreversible damage to the life-support systems of our planet.”
The report confirms what a coalition of 40 conservation organizations said last month, when they claimed there have been “alarming biodiversity declines.” The coalition said that pressures on the natural world from development, over-use and pollution have risen since the ambition to reduce the rate of biodiversity loss was set out in the 2002 Convention on Biological Diversity (CBD).
The first formal assessment of the target, published at the end of last month in the journal Science, is the basis of Monday’s formal declaration. This week’s meeting will see governments pressed to take the issues as seriously as climate change and the economic crisis.
“Since 1970 we have reduced animal populations by 30 percent, the area of mangroves and sea grasses by 20 percent and the coverage of living corals by 40 percent,” said Joseph Alcamo, chief scientist of the UNEP.
“These losses are clearly unsustainable, since biodiversity makes a key contribution to human well being and sustainable development,” he said.
The Science study compiled 30 indicators of biodiversity, including changes in populations of species and their risk of extinction, the remaining areas of different habitats and the composition of communities of plants and animals.
“Our analysis shows that governments have failed to deliver on the commitments they made in 2002: Biodiversity is still being lost as fast as ever, and we have made little headway in reducing the pressures on species, habitats and ecosystems,” said Stuart Butchart, the paper’s lead author.
“Our data shows that 2010 will not be the year that biodiversity loss was halted, but it needs to be the year in which we start taking the issue seriously and substantially increase our efforts to take care of what is left of our planet,” he said.
The failure to meet the CBD target will not be a surprise to experts or policymakers, who have warned for years that too little progress was being made. Last month the head of the International Union for the Conservation of Nature species survival commission, Simon Stuart, told the Guardian that for the first time since the dinosaurs, species were believed to be becoming extinct faster than new ones were evolving.
US President Donald Trump and Chinese President Xi Jinping (習近平) were born under the sign of Gemini. Geminis are known for their intelligence, creativity, adaptability and flexibility. It is unlikely, then, that the trade conflict between the US and China would escalate into a catastrophic collision. It is more probable that both sides would seek a way to de-escalate, paving the way for a Trump-Xi summit that allows the global economy some breathing room. Practically speaking, China and the US have vulnerabilities, and a prolonged trade war would be damaging for both. In the US, the electoral system means that public opinion
They did it again. For the whole world to see: an image of a Taiwan flag crushed by an industrial press, and the horrifying warning that “it’s closer than you think.” All with the seal of authenticity that only a reputable international media outlet can give. The Economist turned what looks like a pastiche of a poster for a grim horror movie into a truth everyone can digest, accept, and use to support exactly the opinion China wants you to have: It is over and done, Taiwan is doomed. Four years after inaccurately naming Taiwan the most dangerous place on
In their recent op-ed “Trump Should Rein In Taiwan” in Foreign Policy magazine, Christopher Chivvis and Stephen Wertheim argued that the US should pressure President William Lai (賴清德) to “tone it down” to de-escalate tensions in the Taiwan Strait — as if Taiwan’s words are more of a threat to peace than Beijing’s actions. It is an old argument dressed up in new concern: that Washington must rein in Taipei to avoid war. However, this narrative gets it backward. Taiwan is not the problem; China is. Calls for a so-called “grand bargain” with Beijing — where the US pressures Taiwan into concessions
The term “assassin’s mace” originates from Chinese folklore, describing a concealed weapon used by a weaker hero to defeat a stronger adversary with an unexpected strike. In more general military parlance, the concept refers to an asymmetric capability that targets a critical vulnerability of an adversary. China has found its modern equivalent of the assassin’s mace with its high-altitude electromagnetic pulse (HEMP) weapons, which are nuclear warheads detonated at a high altitude, emitting intense electromagnetic radiation capable of disabling and destroying electronics. An assassin’s mace weapon possesses two essential characteristics: strategic surprise and the ability to neutralize a core dependency.
