Let's state some facts.
Fact 1. Things change. The world changes. In the long term, continental drift and subduction of tectonic plates will ensure that millennia from now, all traces of the human race would be wiped out.
Even in the short term, weathering by the Terran climate ensures that our presence is a mere blink in the eye of the Cosmos.
The Earth changes, the climate changes, people live and they die.
So why, all of a sudden the preoccupation with the preservation of the globe, as if time can be stopped in it's tracks? Why the huge expense of trying to avert things which cannot be averted? When did the Human race develop the hubris to think they could preserve the planet in aspic and halt millennia of change?
In the short term, we are spending billions trying to keep everyone alive. People that unfortunately are destined to die. From expensive cancer drugs to long-term lockdowns to halt Covid, Governments around the world are expending Billions to keep a small number (0.01 percent) of the population alive. To the detriment of the 99.99 percent of the people that can carry on without issue.
In the long term governments are committed to spending Trillions trying to avert climate change. When the climate changes naturally. We've had Ice Ages and we've had tropical climates. Why are we bankrupting countries trying to stop the unstoppable?
When did we begin to think we are immortal, when did we start to think we could stop time in it's tracks, when did governments decide it was worth spending billions on it?
