Yeap, massive, exponential growth rate of the human population since the industrial revolution, with everyone (naturally wanting all mod. cons and an addiction to consumerism, seems to be the root of the problem (density of plastics in the oceans; pollution; etc.).

Apparently, https://www.worldometers.info/world-...on/#pastfuture

"A tremendous change occurred with the industrial revolution: whereas it had taken all of human history until around 1800 for world population to reach one billion, the second billion was achieved in only 130 years (1930), the third billion in 30 years (1960), the fourth billion in 15 years (1974), and the fifth billion in only 13 years (1987).

During the 20th century alone, the population in the world has grown from 1.65 billion to 6 billion.
In 1970, there were roughly half as many people in the world as there are now."

However...

"Because of declining growth rates, it will now take over 200 years to double again." Well that's alright then.

No worries. A nuclear winter will sort it all out and put us back to normal again. I'm hording turnips and worked flints already.
