      One of the fundamental challenges facing the world is lifting people out of poverty without undermining the stability of the Earth's climate systems.

      In fact "ending poverty in all its forms everywhere" is the first of the 17 United Nations Sustainable Development Goals to create a better world by 2030. 

      The second of those goals is "zero hunger", and the third is "good health and well-being".

      As desirable as these and the other goals are, two of them can come in conflict with one another if policymakers don't take care to prevent this.

      This was pointed out last year in a TED talk by Johan Rockström, a globally recognized sustainability expert and the former executive director of the Stockholm Resilience Centre.

      The eighth goal, "decent work and economic growth", can clash with the 13th goal, "climate action", if decent work and economic growth is achieved through increased use of fossil fuels.

      In the TED talk, Rockström unveiled the Earth3 model, which highlights policies that can lead to prosperity without making more of the planet uninhabitable for human beings.

      Rockström has led an international team of scientists that created the "planetary boundaries framework".

      It outlines the safe operating space for humanity without triggering climate feedback loops that could lead to runaway climate change.
