It’s not this simple.

Nothing is simple. Surviving during the last glaciation wasn't simple yet people still lived. Crossing the ocean without accurate maps wasn't simple yet the oceans were crossed. Developing and growing enough crops to feed 7.5 billion people when Malthus said the planet could not sustain 1 billion people wasn't simple but they were developed and the population is still growing. Landing on the moon, diving to the Marianas trench, reclaiming the 'polders' in the Netherlands, developing nuclear power, writing Beethoven's 5th symphony, writing and memorising "The Gulag Archipelago" to later commit it to paper were not simple but all those things were done.

What do you mean by saying "it's not that simple"?

That the problem is more complex than you’re making it out to be.

Please explain in what sense my explanation simplifies the problem and what would need to be changed to what I propose to make it better. Just saying that "it is not that simple" without saying where I'm wrong doesn't help me better my ways. In short I propose to solve problems instead of meditating on them while retreating from the world stage. What is missing?

I think the big risk is wars caused by climate change and millions (billions?) of refugees migrating from where you once could do agriculture to where you might be able to do agriculture in the future. It's really hard to mitigate those effects.
