All those who are so concerned about climate change ( governments, environmentalists ... ) are even more concerned about their reputation.
At climate conferences they set lofty goals to reduce greenhouse gasses, but they could equally well set other goals like:
reduce world population with 5% by 2050, but they refuse to name the elephant in the room:
80 million people extra every year, who will all need space, food, energy...
They would rather see the world go up in flames than risk being called racist, islamophobic, antireligious...
by pointing the finger to groups or nations that for cultural or religious reasons oppose every form of birth control,
or even actively promote population growth.
That is why the fight against global warming is a lost cause.
