As Earth hurtled around the Sun at over 100,000km per hour, humans were rudely reminded in 2020 by the COVID-19 pandemic that no-one is in charge ― or rather, nature is in charge.
Humanity faces many intertwined global problems in 2021. The short list includes climate change, habitat loss, biodiversity loss, biochemical pollution, overpopulation, demographic aging, food insecurity, water scarcity, disease and pandemics. These problems are both cause and effect of extreme poverty, inequality, forced migration, and social conflict that leads to war.
Hovering above all these inter-twined global problems is the truly existential threat of nuclear war. Nuclear war is the most immediate and direct extinction trap into which the species could fall.
