      Why Understanding Limits Is the Key to Humanity's Future

      "Limitless" is a dangerous word. And not only must we respect limits, we should celebrate and work in harmony with them.

      Recent news articles about a breakthrough in nuclear fusion research heralded the potential for “limitless” energy. Whenever I read that word limitless I wince, because I’ve learned to view it as a subtle instruction to readers to “please stop thinking now.” After decades of false promises to deliver limitless energy, we need to start thinking instead, and search for limits both obvious and hidden. Doing so usually leads to a better understanding of how things really work.

      Fortunately, several other writers have successfully refuted “limitless energy” claims regarding fusion, so it’s not necessary for me to do that here. However, it may be useful to explain more generally why the promise of limitlessness is misleading and sometimes deadly—and why limits are lovable after all.

      'The System' Is Ruining Our Present and Collective Future

      Every morning, the daily news provides fresh evidence that "the system" is heading off a cliff—fruitless climate talks; growing nuclear threats; microplastics in food, water, breast milk and newborn babies; oceans damaged by warming, acidification, and dead zones; the military-industrial dragon preparing for war with China; Congress out of touch and deadlocked….

      World Leaders Must Come to COP15 Biodiversity Conference to Succeed

      In Montreal this month, governments will come together at the Convention on Biological Diversity's COP15 summit to negotiate a global deal for nature.

      The recent United Nations Climate Change Conference (COP27) in Sharm El-Sheikh offered encouraging but insufficient signs of an emerging political consensus on the need for global solidarity in the face of global warming. Now, world leaders need to attend to another existential risk to people and the planet: the alarming and growing loss of biodiversity.

      Given the current rates of biodiversity loss, some scientists estimate that we are on track to lose three-quarters of the world's species within only a few centuries.
