  Humanity Under Threat From Perfect Storm Of Crises-study

太阳城中心app下载  The world is facing a series of interlinked emergencies that are threatening the existence of humans, because the sum of the effects of the crises is much greater than their individual impacts, according to a new global study.

太阳城中心app下载  Climate breakdown and extreme weather, species loss, water scarcity and a food production crisis are all serious in themselves but the combination of all five together is __71__swift action is taken the risks of each, creating a perfect storm that threatens to engulf humanity unless swift action is taken.

  The links among the crises are clear in many cases, but the methods the world has chosen to try to solve them do not take account of these connecting factors. For instance, extreme heat waves can add to global heating, because they __72__ vast amounts of stored carbon from affected ecosystems, in a feedback loop. It has been seen clearly in the Australian bushfires, which are already __73__ significantly to the store of carbon in the atmosphere.

太阳城中心app下载  The links do not stop there: as the heat waves damage natural ecosystems, killing off wildlife and flora, they also lead to greater water scarcity, an in turn damage agriculture. These combined effects exacerbate the harm done to people struggling with food and water shortages, in a __74__ cycle.

太阳城中心app下载  Faced with these crises in nature individually, it could be possible to fix the problems causing them. But confronted with multiple inter linked emergencies that in combination amplify one another’s impacts, people are facing __75__dangers and many communities cannot cope.

太阳城中心app下载  The report, which took the form of a survey of 222 leading scientists from 52 countries, conducted by the international sustainability network Future Earth, found that the responses to these emergencies by governments, civil society, business and institutions did not recognize their inter link nature. Trying to solve the problems individually, without taking account of the “cascading” impacts, was likely to be ineffective, the scientists said.

  While the risks are amplified when they are connected, so too are the solutions, however. Whenever action is taken to remedy environmental problems, the benefits also cascade: for instance, __76__wildlife and flora in a wetland can also reduce water pollution and soil erosion, and protect crops against storm damage, __77__water scarcity and allowing for more food production.

  “Despite the __78__of connections, many scientists and policymakers are embedded in institutions that are used to thinking and acting on isolated risks, one at a time the report says. "This needs to change, to thinking about risks as connected.”

  Amy Luers, the executive director of Future Earth, said: “2020 is a critical time to look at these issues. Our actions in the next decade will determine our __79__future on Earth.”

  The authors of the report urged a change in the way risks were handled: “We call on the world’s academics, business leaders and policymakers to pay urgent attention to these five global risks, and to ensure they are treated as interacting systems, rather than __80__one at a time in isolation.”
