GS 3: Environment |Conservation, Environmental Pollution & Degradation

Why in News?

  • Saving the diversity and abundance of life on Earth may cost $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.

Global Deal for Nature (GDN):

  • Scientists have proposed new science policy to reverse the tide, called A Global Deal for Nature (GDN).
  • It is a time-bound, science-based plan to save the diversity and abundance of life on Earth.
  • The GDN campaign is being driven by One Earth, an initiative of the Leonardo DiCaprio Foundation that aims to gather support from international institutions, governments, and citizens of planet Earth to support ambitious conservation goals.
  • The policy’s mission is to save the diversity and abundance of life on Earth — for the price tag of $100 billion a year.

What would GDN do?

  • 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.
  • The study outlines the principles, milestones and targets needed to avoid the disastrous extinction threats of a two degrees Celsius global warming forecast.

Why GDN?

  • Scientists now estimate that society must urgently come to grips this coming decade to stop the very first human-made biodiversity catastrophe.


  • To protect biodiversity by conserving at least 30% of the Earth’s surface by 2030;
  • Mitigate climate change by conserving the Earth’s natural carbon storehouses; and
  • Reduce major threats.
