While iconic species like lions or elephants are more likely to benefit from conservation efforts than an unfortunate toad that almost no one other than biologists have heard of, I'm not as sure as you that those iconic species are safe. Habitat loss and poaching are still major problems, so it's likely their decline will continue.
We should all hope there won't be more extinction but it seems inevitable. A survey just concluded the African elephant population shrank by 30%. There are just around 300,000 left...This is appalling but may be unstoppable, as a growing human population leads to habitat loss and poaching.

I do think that we should find a way to manage the proverbial "sustainable growth" [I'm an environmentalist, but I'm not in agreement with the steady economy theory: humans want to improve, it's natural for us].

What probably will help us a lot, will be the capability to travel to other solar systems, may be more aware of life in general and of the importance of the biosphere of a planet. I guess that our descendants who will reach the stars will avoid to cause the extinction of so many species on the new earths ...

NZ Extinction Capital of the World


Think of New Zealand as the extinction capital of the world ..... To understand the damage humanity can wreak on irreplaceable flora and fauna, New Zealand is the place to be.


The renowned American biologist Jared Diamond calls the extinction drivers the four horsemen of the apocalypse. Humans hunt, destroy native species' habitat, and introduce competitive exotic species. When one species becomes extinct, it also brings about the extinction of species dependent on it. .....

"Because New Zealand was the last major land mass to be colonised by humans, there is still lots of evidence of what was here originally," says Blackburn. "Roughly a third of the bird species that lived on these islands 800 years ago are extinct. Gone forever. You had 11 species of moa and this was the only place in the world they lived. No one will ever again see a living huia, or a piopio. Or hear their songs."
The effect of exotic species introduced by humans is widely acknowledged. However, the worst invader is humanity.

How does it go? Past behavior is the best predictor of future behavior. Despite the knowledge & all the efforts to mitigate, one deludes themselves to think the creatures of this world can survive the onslaught of climate change, loss of habitat & slaughter for profit. Will this continue? Its only the pace that's in question.

There will be more extinctions even if we try to stop them, the impact of human development is too widespread.
Also it must be noted that not all extinctions are the fault of humans, they have occurred throughout the period where life has existed on this planet. Of the total number of species known to have ever to have existed 99.9% are now extinct

They will always keep happening until something makes us go extinct. It's how nature works. I hope the rate slows down though to the point where we can keep the ecosystem stable and evolving at a natural rate.

^ unfortunately there is no 'natural'. The entire planet has been modified by human impact. And sorry to be a downer, but the rate will not slow as human population continues to increase.

Another example of how humans create & often destroy wo even realizing it. Of course those who managed those towers over the last 50-60 years certainly noticed the thousands upon thousands of dead birds?
