World Earth Day: Saving the planet may cost USD 100 billion per year
   Date :23-Apr-2019

SAVING the diversity and abundance of life on Earth may cost USD 100 billion a year, say scientists who have proposed a policy to prevent another mass extinction event on the planet. There have been five mass extinctions in the history of the Earth. Scientists now estimate that society must urgently come to grips this coming decade to stop the very first human-made biodiversity catastrophe. “The sixth extinction is on our society’s shoulders; it really is,” ecologist Greg Asner, of Arizona State University in the US, said in a statement on the occasion of Earth day. Asner is one of 19 international authors with a bold new science policy proposal to reverse the tide, called A Global Deal for Nature (GDN).
The policy’s mission is to save the diversity and abundance of life on Earth -- for the price tag of USD 100 billion a year. It’s not a huge price tag, said Asner, consider that in 2018 alone, the top two most profitable US companies, Apple and Berkshire Hathaway, almost matched that amount. Societal investment in the GDN plan would, for the first time, integrate and implement climate and nature deals on a global scale to avoid human upheaval and biodiversity loss.
While the 2015 Paris Climate Agreement was the first major accord to take global action toward climate change policies, the international team of GDN scientists believe a similar companion pact is desperately needed to implement the very first global nature conservation plan to meet these challenges. “The Paris agreement is only a half-deal; it will not alone save the diversity of life on Earth or conserve ecosystem services upon which humanity depends,” said Eric Dinerstein, of the US-based non-governmental organisation Resolve.
