For 100 million years Earth has been a Galactic Park sort of like Yellowstone and Yosemite National Parks

There have been Galactic Forest Rangers managing the wild life on earth that long. Presently, the human wild life has overrun the planet and needs to be thinned out because otherwise all the other species are going to go extinct. 8 billion humans is too much because the most amount of humans that can be sustained her on earth's surface for thousands of years is around 1 billion humans in relation to all the other species here.

So, humans are being allowed to thin themselves out through Coronavirus and Global Warming this century. Wars won't work because of nuclear weapons which could end earth completely. So, pandemics and Global warming is thinning us all out.

If you take the planet and divide the populations of each country by about 8 then you will see what populations will look like planetwide the way all this is presently going.

For example, if I said the population of the U.S. is around 328.2  million you would divide that by 8 to get forty-one million twenty-five thousand.

This is likely the population of the U.S. in 2100.

How will we get there?

Likely coronavirus and other pandemics and Global Climate change. 

For example, 3 hurricanes (typhoons) have or will hit Japan and South Korea this week and last week two hurricanes hit the gulf coast (Marco and Laura). This is the future of hurricanes and typhoons where multiple hits will occur within 24 to 48 hours on the Carribean and Gulf coast and also into Japan, South Korea and China and India and other Asian localities. These will drastically reduce human lives over the course of this century in addition to pandemics which could mutate directly or indirectly out of the present pandemic to arrive at a population worldwide of between 100 million and 1 billion left on the planet by 2100 AD.

This appears to be where all this is going as of now.

Will human beings eventually go extinct?

I don't think so but technology might go away if we are reduced below 100 million people which might be a limit to how many people we can have and still maintain enough technologists to sustain our technologies for thousands of years into the future.

There are many unanswered questions at this point that you will have to figure out.
