The Sixth Extinction

No thanks. Your posts speak for themselves to anyone who reads the thread, which I am satisfied with. I won't be drawn into another cyclical vortex of non-sense with you, where you move the goal posts or split hairs in order to desperately prove a failed point. Your denial of reality is so easily triggered that it makes it impossible to have a substantive conversation with you. As soon as you see something you doubt or disagree with, the blinders go on.

Again, no thank you.

I mostly came here to test you and see what you're really about. Now I know, and I'm appalled. No point in going further.

‘Appalled’

Carrier pigeons is a better example. Dodos were rare to begin with. There were tens of millions of carrier pigeons.

On the plus side there are species that would not have survived without man.

Please point out where I wrote "climate change" in that post. :roll:

Well isnt your OP all about a gazillion species will go extinct due to man made climate change? ;)

A new report Extremism Rebellion – A review of ideology and tactics from the think tank Policy Exchange looks into the behaviour and background of Extinction Rebellion. It’s also discussed in the Telegraph here and here: As the paper shows, the leaders of Extinction Rebellion seek a more alarming agenda than pure environmentalism, one that … Continue reading →

Yeah because calling somebody a "knownothing" who is trained in the field you are talking about and has presented evidence that is greater and more accurate than your own isn't attacking someone's character. Furthermore, lying about the very events and details of the conversation in order to retroactively paint a different picture is nothing short of manipulative.

Keep on smoking whatever you're smoking. :shrug:

I'm still waiting for you to debunk the UN meta-analysis, and the two peer reviewed studies from Journal Nature that I posted earlier. You haven't done that.

But I do see that you keep posting propaganda articles.

"Knownothing" is not a character comment. It's a denigration of an explicitly anti-knowledge position. And you again refer to "lying" without foundation.

Your posts were off topic. I was discussing extinctions; you were citing threatened species.

You're hopeless. This has been entertaining though.

Not many.

Perhaps one day we'll be able to create new species through artificial DNA.

Conservation has saved many species, some of which were going extinct in the natural course of things. We talk of climate change like it is a recent thing. Hardly. The climate has always been changing. Flora changes, predators arrive, food sources move or die out. Extinction is part of natural history. Man has contributed on both sides of the balance, both condemning and saving.

Climate change and extinction of species, along with evolution of new species has been going on for millions of years, very slowly. The difference in the anthropocene era is the speed with which all but evolution is happening. Now, if only we could speed up evolution to match extinctions, that problem would be solved.

But, we can't.

Extinctions are declining.

Don't start on directed evolution. That is a dark alley and a dangerous one.

Extinctions are not necessarily slow. A new apex predator will wipe out what had been the top tier. Any habitat is subject to change. As you say, it is often slow. Sometimes it is very quick--volcano, earthquake, insect infestation, fire, disease, change in a river course, etc. On balance it is not easy to tell if man has been a help or hindrance of the last century.

Agreed, they are not necessarily slow. The extinction of the dinosaurs happened very quickly, due to the meteor strike. Other great extinctions have also happened quickly, generally due to sudden climate change. The current extinction is also happening quite quickly relative to the past several million years. It is evolution that happens slowly, so it takes a long time for biodiversity to return to its normal level.

You may be right about directed evolution as well. When humans begin experimenting with DNA, the results are anything but certain.

Extinction of species adapted to survive in specific geographical locations is rapid, especially once invasive species are introduced.

Invasive species are Australia's number-one extinction threat

See the Dodo, Tasmanian Tiger, passenger pigeon, etc.

Yes, and when the climate of that specific geographic location changes, extinction can proceed quickly as well. That's precisely why extinction is occurring so quickly currently. Invasive species have been transported around the world by humans, and local climates are rapidly changing due to anthropogenic global warming.

And climate change is allowing many invasive species to thrive exacerbating the damage. But don’t let our resident “all’s well” crowd know that. Their bubbles may burst.

I wonder if Trump thinks that invasive species are a hoax perpetrated by China as well?
