Peter Watts (SciFi author) has a phrase: 'Signposts en route to oblivion'
Hey look, this is one such signpost
Majority of humanity sitting in the passenger seat staring at their phones: ..... Huh, wah? .... Oh, ok ... goes back to looking at phone
More like majority of humanity is like "oh shit, we should stop there's no road ahead!" And the driver is just like "nah"
I wish, but most humans are stuck on the "there was a road untill here, we will find a new one. No need to slow down for that. There always has been a road." sentiment.
What should i do? Stop eating crab? Its about 20 years too late for that, as ive never eaten crab.
Short of devouring the rich, which im only stopped by lack of a ride and a barbed wire fence, or eco-terrorism which for legal reasons i have to clarify that i do not support and have, like totally never engaged in, theres not much i can do.
My carbon footprint is so shallow that it might as well be flying. Yet the world still burns.
Toss it on the pile of horrible signs of things to come.
We can use them to warm us and cook each other for food as the last humans die out, neato.
I am curious how long it will take for them to recover. 90% is a huge population decline.
There are many factors that play into that.
First off each female can produce 100,000 eggs per year. So even thos a 90% decline in numbers sounds horrendous, the population numbers can be replaced quickly.
It takes 5-8 years for the crabs to reach full maturity and start reproducing. Harvest size for the males is 7-9 years.
So on first look you think around 8 years for the population to recover.
However in nature something tends to fill the vacuum left by the decrease of a population. Other species who compete with the crabs for food increase in numbers.
Then there is the die off of predators that relied on the crab as a food source. This might allow the crab population to increase faster than normal.
There is also the increase of predators that feed on the species replacing the crab. Supressing the competition to the crabs.
Each of these species has their own lifecycles and timing.
So the bottom line, it could take 6 years or 600 years. We don't know.
They probably lay 100.000 eggs because only 100 make it into adulthood and the others don't hatch, get eaten, sick or starve before...
In a stable population, 2 would make it to adulthood every generation. If an adult female produces eggs for 10 years, that's 1:500K make it to adulthood. The ocean has a lot of hungry mouths.
Well that’s quicker than I was anticipating.
They also might just go extinct. We literally don't know.
Never; they'll go extinct with all (including us the people).
Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:
How much each change to the atmosphere has warmed the world:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
