The world has just over a decade to get climate change under control, U.N. scientists say, according to the Washington Post. 9/11 and its source- terrorism, cost the USA alone $2 Trillion in unproductive expense.
In the last 20 years, we have had three global emergencies- 9/11 – Terrorism, the 2008 financial crisis and the COVID-19 Pandemic. Plus, one more if you count the effects of climate change.. In addition, there are innumerable national and local disasters every year. We can name incidents related to fires, hurricanes, floods, earthquakes, tsunamis, nuclear meltdowns, chemical explosions, etc.
