What Earth Without People Would Look Like

Raynor writes "Imagine a world without people. What if every human being, all 6.5 billion of us, were suddenly abducted and the planet was left to fend for itself? The planet would heal. 'The sad truth is, once the humans get out of the picture, the outlook starts to get a lot better,' says John Orrock, a conservation biologist. Pollution would cease being created. It would remain around for many years, CO2 taking as long as 20,000 years to be restored to it's natural level, but will decrease. Even if we were all whisked away and our nuclear reactors melted down, it would have a surprisingly little effect on the planet. Chernobyl gives hope to this end. 'I really expected to see a nuclear desert there,' says Ronald Chesser, an environmental biologist. 'I was quite surprised. When you enter into the exclusion zone, it's a very thriving ecosystem.' In the grand scheme of the world there would be little evidence of our existence at 100,000 years. The most permanent piece is the radio waves we've emitted of the last century. As the article puts it, 'The humbling — and perversely comforting — reality is that the Earth will forget us remarkably quickly.'"

    'The sad truth is, once the humans get out of the picture, the outlook starts to get a lot better,'

    But for what purpose? That's like never opening a package, so it never gets finished.

    Who would even appreciate it? Is the Earth something so deistic and magical that's its mere existence is good enough by itself? Or, is some alien race (no doubt evilly destroying their own planet) going to come by and appreciate its pristine beauty?

    The planet is here, and we are using it. We are becoming better, and making it more capable. To say that to conserve, take notice, and be proactive, to make it last longer, is not only true, but it is helpful. To say, however, that if we were gone it would be better, is an unproven theory, and would remain unproven, being noone would be here to care.

    Growth takes a toll somewhere. But not for naught. The Earth is here for us, and we have made quite some progress based on her resources. There's no reason to replace our pride with some pessimistic view that promotes nihilism in some strange way.

      Actually, did you not find it amusing that during the course of all of this speculation about what would happen on the earth without humans, the guy makes the point that he was totally wrong in his thoughts about what the area around Chernobyl would be like?

      The guy basically tells us that his predictions about ecosystems are for crap anyways, so why the heck should we listen to his current one?

    What's sad about that? Do you cry every night knowing that the time you spent in your house added to its deterioration?

    You can view this as we are abnormalities in our ecosystem. We are atypical organisms living beyond what we are supposed to.

    Or you can acknowledge that if other organisms were intelligent enough to make their existence better for them (at the expense of others), they would. That's one of the laws of nature and we're just reverting back to our primal instincts. Now, we're fairly civil and modest in reproducing and killing, so we're a bit better than the animals in that respect. If we chose to acknowledge that we're destroying earth for the rest of the organisms, it would probably be both civil and intelligent. Unfortunately, about half of us don't give a shit. Well, that's what we deal with.

    Every organism is in competition for resources with every other organism in some way. A symbiosis rarely occurs and when it does, it's usually forced (humans raising cattle for milk).

    Is there any scenario we can reach where we won't destroy the environment?

    Probably not but, in my opinion, humans are entropy.

    The humbling - and perversely comforting - reality is that the Earth will forget us remarkably quickly.
    And, if you acknowledge the very long history of the earth, we are remarkably new to the earth. The dinosaurs had a longer reign and they are forgotten with the exception of their bones.

      We're not abnormalities. We were created by the eco-system. Then we gamed the (eco)system and beat it. Think our lack of fur makes us unable to survive ice-ages or cold climates? Fuck you, eco-system, we're going to kill some animals and wear their fur! No wings? Fuck you, eco-system, we're making planes! No gills? Again, fuck you eco-system, we're busy evolving Jacques Cousteau and a crazy machine that lets us breathe underwater! Antibiotics -- win for us. Language -- win for us. Brains filled with the ability to learn -- win for us. Crazy-ass opposable thumbs -- win for us. Neil Armstrong -- win for us.

      We're the winners. We rule. As a species, we're at the top of every single food chain on earth, local irregularities notwithstanding (for instance, I would not try to argue this point with a bear, shark or tiger). As long as, as a species, we act smart, we're likely to stay there. That means being responsible, not wrecking things for the next generation, conserving what we have, acting sustainably, and if needed, figuring how to removing unstable elements and memes from our global society (religious fundementalists, dictators with nukes and itchy trigger fingers, etc.). (Oh, and figuring out how to get off this rock long term, so we can beat the sun at its "burn out after a billion years" game too.)

      You're free to disagree with me, but I like being on the winning team as a species. I am much happier as a videogame-enjoying human than I would be as an anonymous ferret or weasel or whatever.

    In 1.5 billion years the sun will start to grow into a red giant and solar winds winds will strip the Earth of its atmosphere.

    Then in about 5 billion years after that, the sun will have consumed the Earth and whatever life remains on it.

    This is of course barring large iron metorites or collision with large space bodies and of course a passing of another solor system or galaxy in the meantime.

    So if man went away tomorrow... Life would be peachy for nature for a while, but then it would die by itself due to reasons far beyond non-intelligents life control (unless dolphins evolve into space faring creatures on their own)

    So nature has to put up with man for a while to we figure out how to get off this rock... Or get used to not being around in a few billion years.

    Probably the biggest PR mistake that environmentalists ever made was that they made their activism about "The Earth", and not about our ability to survive on it.

    Nature is a resilient bitch. We could hardly do the kind of damage necessary to make Earth unlivable by something.

    We can, however, make life very unpleasant for mankind. And that's why we need to preserve the environment as best as possible. For us, not the environment.

  8. Just plain stupid by cdn-programmer · · Score: 4, Insightful

    This is just plain stupid. Nice he harps on CO2.

    Little does he know. During the Ordovician CO2 levels were 13x to 17x higher than now. The earth slipped into a deep freeze snowball phase during this time. Throughout the Carboniferous CO2 levels were much higher than now. Back in the PreCambrian CO2 was much higher than now... up into the 80,000 ppm range in fact compared to 370 ppm now.

    So not only is the story just plain tripe - it is also based on a poor understanding of the history of the planet.

    I always thought the Dinosaurs were the most dominant life form. Give me a break!

    You laugh, but China's population is seriously unbalanced. There's not enough women for something in excess of twenty percent of China's men. They're either going to have to have a war (a really big one, or one where they sacrifice a lot of troops) or embrace homosexuality because the rest of the world's women don't want them - Chinese men typically do not have much respect for women, it's not exactly a cultural value for them.

    Animals hurt the planet they live on too. Throughout evolution, there have been entire species killed off by more dominant species, and groups of animals have spread to other areas and changed the environment there to the detriment of what already lived there.

    I think some people put up an anti-mankind mindset to make themselves feel like they're hip and intellectual, and I doubt our impact on the environment is as great as global warming alarmists have made it out to be (I notice Slashdot didn't report about the lack of an active hurricane season this year or the recent below-average temperatures).

    We're hurting each other and also other animals and plant life on this planet. How many species of animal and plant have become extinct since man became the dominant species on this planet?

    Every single species vanishes. Go back far enough and every single species that once was is no longer. Everything goes extinct in the end. I am not advocating wanton destruction, but simply pointing out that the "ideal" of dropping the world into a Ziploc bag and preserving it forever is a completely human desire that evolution and natural selection doesn't give a shit about. All the humans could vanish tomorrow and that still wouldn't prevent every single species on Earth from going extinct at one point or another.

    So, instead of worshipping and unchanging Earth as some quasi-mystical religion, how about we focus on something that matters? We should be preserving our own asses. Part of saving ourselves might very well mean taking a good hard look at how we are changing the planet. Mother Nature does not give two shits if we cook the Earth and will happily (if nature could feel feelings - which it can't) cook up some happily little bacteria that loves CO2 and warm weather. The humans on the other hand might find it getting mighty uncomfortable.

    So screw this quasi-mystical Mother Nature crap. Mother Nature doesn't give a shit about the species of this planet and it doesn't care if all the bunnies die. We are the ones who care. We care if the world becomes inhospitable to us. We should be working to improve the environment not because of some deluded worship of the Earth in its exact current state which is going to pass regardless if we like it or not, but should be working to improve the environment for our own sake.
