Phanerothyme Posted June 7, 2019 Share Posted June 7, 2019 (edited) Yeah - sorry, I should have pointed out the obvious corollary - organisms reproduce and grow to the limit of available resources or die out. You're right - pandas have evolved perfectly for their rapidly diminishing evolutionary niche, but hey would have already died out if it wasn't for human intervention. To what extent are humans not reproducing and growing to the limit of available resources? It strikes me that all life is driven to live. That means consuming resources for energy to create ordered systems out of disordered matter, and reproducing. 4 hours ago, CaptainSwing said: Because we are, as far as we know, the only species that can understand what's happening, and could try and do something about it. [Also, I guess that populations of r-selected species don't grow to carrying capacity, if you still buy into the r/K schema.] no idea what r/K Schema is. I don't believe that individual understanding of the world translates to behaviour on the part of the species.

Voice of reason Posted June 7, 2019 Share Posted June 7, 2019 Humans are also organised as a mass, not purely individual creatures. This makes us able to plan our actions as a species to a degree or in theory. Link to comment Share on other sites More sharing options...

Look at it now, probably the cleanest river in Europe.. Just proves that mankind can solve problems, when it wants. Look closer to home and what the Rother and the Don were like when we were kids.

I remember reading in the late '80s that by the year 2000 there would be no more woods or forests left in Europe due to acid rain. I wonder how that turned out?

They probably calculated that based on fuel efficiency and consumption at the time. Link to comment Share on other sites More sharing options...
Car Boot Posted June 8, 2019 Share Posted June 8, 2019 I thought the rich kids who run 'Extinction Rebellion' told us we only had ten years left? Now we have seventy? Link to comment Share on other sites More sharing options...

Oil companies have developed technologies that allow them to get at previously unreachable deposits since then as well - not to mention exploiting tar sands, fracking and discovering new oil fields.

hauxwell Posted June 8, 2019 Share Posted June 8, 2019 I remember the late Stephen Hawkins saying we must find a new planet in the next 200 years as earth is doomed. Wish they would make their minds up how long we have got. If that’s the case they need to start advertising for more astronauts to search the universe.
