ok i was reading these comments for a school prodject and i read something that really confused me, it said that global warming was a nateral thing, but its not. global warming is happening because we humans are putting dangerus gasses into the air and those gasses are thining out the ozone layer, which protects us from the suns rays, and its the worst over the places like the arctic so its melting the ice and the snow that helps animals like the polar bear survive, so no global warming is not nateral and its still our falt that those animals are dieing

I Think that the orangutan will go extinct in the next 20 years! Even if they dont go extinct in that duration, I want to have an encounter with one soon. one day (my estimation is 150 years), every species we have discovered will go extinct. The ones we havent will not. I think all the undiscovered species would be bugs and other less favourites. If anyone has seen the tv series "PRIMEVAL" than you would understand. the world would probabally look lifeless, but before you know it, you would find your self being in a kill or be killed situation. If this is still up on the internet, and the last living human soul, good luck with your last duration of life!

Humans are actually the rarest of the rare. Those who think humans should go extinct should take a chill on their stance or find some way to change into some other life form - preferably one that doesn't speak. If humans were to become extinct, the probability of another species evolving to possess anywhere near the capabilities of humans in terms of consciousness and abilities to manipulate its surroundings and communicate is practically zero. Nothing compares. Although nature constantly driving towards convergent evolution to fill similar niches, there will never be another like us if we go. Even the hominids that have come and gone do not compare, and our closest living relatives, the chimps, bonobos and other great apes, only develop language, scientific knowledge, and culture in fictional stories after man gives them these gifts - we get to see this in the new Planet of the Apes movie coming out soon! We too are part of the natural progression of things. I concur that we can do a better job with how we treat the planet and our fellow beings, as it is only in the best interest of mankind to do so, but extinction of the human species - come on! Time to go hang out at the mall and do some people watching - fascinating Read more: http://www.smithsonianmag.com/specialsections/40th-anniversary/Five-Species-Most-Likely-to-Become-Extinct-in-the-Next-40-Years.html#ixzz26YIpSLKQ

hello if everyone is so bothered about these animals, why are you not out there trying to help them?, or stopping people cutying their home downs? i would be doing this myself but as i am only 12 i am not able to......

"humans are the rarest of the rare"? lol. gee, who said that? oh yea, a human did.

Humans are the scourge of the earth. We take more than we need or deserve and then ask for more.

The way so many kinds of creatures are disappearing or dwingling away makes me believe that we are "out of whack."

I agree with M.S.

Sure, extinction is a natural process (e.g. dinosaurs) and it has happened so many times in Earth's history. Some species make it and some just don't. But those are extinctions that happen due to natural causes like disease and climate change. I think that the treefrog falls into that type of extinction.

But when humans are involved in the ending of a species due to the destruction of their habitat from pollution, poaching, illegal animal smuggling, or making stuff like monkey balm, then it's a completely different matter. There is nothing "natural" in that. Someday, it's possible that our great great grandchildren will think that all animals live in the zoo and that rainforests are a fairy tale.

Of course, let's make sure we get the poor human species on this list. Give it a rest. Of course, extinctions occur naturally but when they are caused by human carelessness, it's inexcusable. The passenger pigeon and the dodo weren't lost to natural processes.

There are six billion of us and we're going to make sure we take every other species out before we go. We are the worst thing to ever happen to this planet.

The sooner humans go extinct the better for every other living thing on planet Earth. Maybe the next species to attain "intelligence" will really be intelligent, and not just some psychotic, mutant, monkey freaks with a fetish for death and destruction.

There are 6.5 Billion humans on earth growing an an exponential rate. In order to save species that have limited range, it would seem only logical to curb the species which is most resopnsile for other species extinction. For example, the Mexican illegals care absolutely nothing for endangered species, and would kill the last one of a species out of pure ignorance and lack of consideration of some lowly form of life. The elitists which clammer for multiplicity among humans, give little thought that the only people to survive in a complex world, should be those with the intelligence to understand why biodiversity is so important not only for our own biological survivel but also for our psycholoogical sanity.When man is the only viable organism left on earth, the dspair of it all will create a madness of extinction.

Since the beginning of this planet and life on it there have been massive extinctions. This is normal. If they had not occured then man would not be here today. These extinctions made room for man and the other species that are here today to develop. Global warming is also a normal circumstnce which has been occuring regularly throught the times. This also causes extinctions and is quite normal. Extinctions are not a man made occurance, although on a very small scale man may push species away.

Its highly unlikely man will destroy himself or the world. We are just too small to be able to do that. This planet has been around for billions of years and has gone through catastropic changes which were much bigger than we can do to this planet and it got through those changes quite fine. Changes are naturally and there's nothing that says we humans are to be here permanently.

We don't need an ecosystem and we certainly do not need lesser creatures slowing down or impeding the progress of this Great Society. It is time we did what everyone knows in the back of their mind is correct- use chemicals to destroy all of the indigenous life on the planet so that we may inspire Humans to explore the Cosmos! Hail Scientism!
