Wealth and power was not evenly distributed in the Greenland Viking colony; a few powerful leaders made decisions that impacted everyone. The same is true today in many regions of the world. The World Bank estimates that about 40% of the world’s population lives on less than $2 a day; almost half of the 2.2 billion children worldwide live in poverty. A small percentage of our population (perhaps 20%) controls 80% of all resources. Actions by the wealthy today that degrade the environment degrade it for all sooner or later.
