War and preparations for war are — although you’ll never hear it from well-funded environmental groups — huge causes of environmental destruction (not to mention wasters of resources that could be used for environmental protection beyond our wildest dreams). That case is made at https://legacy.worldbeyondwar.org/environment
Embedded below is a great new summary by Pat Hynes of what we know on this matter, including this interesting tidbit:
“The projected full costs of the Iraq War (estimated $3 trillion) would cover ‘all of the global investments in renewable power generation’ needed between now and 2030 to reverse global warming trends.”
Of course war preparations are far more costly than wars. The United States spends about $1 trillion per year, and the rest of the world combined another $1 trillion. The world could halt military spending for a year and a half and instead fund the actual defense of the world against the actual danger of global warming.
