Thanks, Plum. :-)Bill, an excellent video! Thanks so much. :-) iceng 10 November 2019 Sunflower sea stars are a hardy group..I can believe the temp could deter breeding..Bet the people at the Monterey Bay Aquarium could breed or show how to breed these :-) Bill_I_Am 26 October 2019 Isn't it amazing? And it all makes perfect sense. I was so impressed that they were able to pull that story together over the decades! Returner 26 October 2019 @Bill_I_Am - thanks for the video on The Serengeti Rules. It opens my mind. Bill_I_Am 25 October 2019 Thanks, Plum. PKH has it right. Balance. Sea urchins are out of control because their predator has been wiped out, probably by humans. This outstanding Nature program explains the whole concept beautifully. I can't recommend it highly enough.https://www.pbs.org/video/the-serengeti-rules-41dfru/ Plumpossum 25 October 2019 A glimmer of hope? Thanks, Returner. Returner 25 October 2019 Human population growth is slowing.From https://www.worldometers.info/world-population/#growthrate:"Population in the world is currently (2019-2020) growing at a rate of around 1.08% per year (down from 1.10% in 2018, 1.12% in 2017 and 1.14% in 2016). The current average population increase is estimated at 82 million people per year. "....World population will...continue to grow in the 21st century, but at a much slower rate compared to the recent past." Plumpossum 25 October 2019 Thanks, PKH and Returner. You are both right. I wonder by what percentage the human population increased in five years...? Returner 25 October 2019 Environmental consequences seem to turn up every day now, often from something I'd never heard of, like purple sea urchins -- a 10,000% increase in their population in five years. pumpkinhead 25 October 2019 It's all about balance, isn't it. When something in the environment goes wonky, the effect ripples throughout. A very interesting and eye opening article, Plumpossum. Thank you. Why this advertisement?
