Not many people seemed too cracked up about the straightedge Bob Marley tattoo, so I'll try again with another photo of interest. I wanted to share this kooky piercing from Matt Bruce over at Spitfire Tattoos in Victoria, BC (where I was born). It's a surface piercing through the end of an amputated finger stump — although I should mention that he only did the piercing, not the amputation, so don't go calling him asking for chisel services!
I've talked a lot here about very calamities facing humans around the world, but I thought I'd take this opportunity to put my assessments of some of them into context. I'm going to split them into ones that scare me and ones that don't.
Apocalypses that don't scare me
The events in this section playing out would be terrible and could hurt or kill a lot of people. However, they're not ones I'm scared about either on a humanity-level (ie. I don't think they'll do significant damage to humans) or a personal level (ie. if they occur I believe I can minimize the damage I face myself).
Peak Oil
Big fucking deal. Yes, it will suck like crazy if it happens too quickly, and will bring with it wars and economic collapse, but it's not even going to come close to killing off humans or the planet. The end of oil is simply the world's biggest inconvenience. This planet is bathed in energy. We've got more than enough, especially if we start using it more reasonably.
War and Terrorism
The fact is that war, terrorism, and violence just don't kill that many people, and kill almost no one in wealthy countries. I'm a well off person in a well off country. If I fall victim to death from war, it's almost a freak accident. While there are WMD attacks that can do incredible damage, and in the future could do huge damage to even a first-world nation, we're still talking about comparably small numbers… and we've got so many humans on this planet that killing a few is just a tiny impact.
Plague and Pestilence
Even if we imagine a megaplague that kills 30% of the world population, it's very survivable, and again, wealthy people in wealthy nations, especially those who aren't urbanites, shouldn't have to worry too much. If a plague (”natural” or weaponized — more) were to break out, the end result — after getting through it — would be a healthier society.
Economic Collapse
The above three, or other factors, could lead us to economic collapse. Economic collapse can lead to massively increased violence, lawlessness, and assuming they haven't already happened, the calamities above. But again, while they can make life suck for twenty years, they're inherently survivable assuming we have the facilities to grow food.
In minor cases, the apocalypses above could create disturbing and oppressive political changes, but those could happen even without disaster. Even in a worst case scenario I don't believe that any of the above have the potential to knock us back any further than 1800s-level technology. Which sucks, but really isn't a big deal in the grand scheme…
Apocalypses that scare me
These scenarios are ones that I believe could destroy the human race, or enough of it to knock us back to the stone age. I also believe all of these are inherently possible.
Human-Robot Apocalypse
I've written on this in the past, and the idea has been recently popularized in the movie I, Robot. In simple terms it happens when machines gain both sentience and control over enough of their “ecosystem” (ie. manufacturing, design, energy production, etc.) that they can stand as an independent species. The problem is that they're a species with fundamentally different and incompatible needs. I do not believe that we can safely co-exist — or at least I'll say I'm not sure enough — that we can co-exist to bet humanity on it.
Slow adoption of Veganism
Long term, we do not have enough meat (chicken, beef, pork, fish, etc.) to support the number of humans we have, even just in the West, at the current rate of consumption. Right now we are destroying our water systems, cutting down our forests, depleting our oil supplies, and overfishing the oceans to indulge our taste for animal flesh. If it was just a matter of stopping eating meat when it runs out that would be fine, but it's not that simple.
Destroying the planet's forests — the Earth's lungs which clean and stabilize our atmosphere — is suicidal. What's even worse though is overfishing (look what we've done to cod — more). Just like the forests breathe for us, so do the oceans. By destabilizing the marine ecosystems, we are massively raising the CO2 levels in our atmosphere (more), which can snowball out of control very quickly, leaving us with a planet with air that is no longer breathable by most land-dwelling creatures.
Severe Water System Damage, Pollution
While running out of oil just inconveniences us, running out of fresh water supplies kills us, and much of the ecosystem along with us (as does pollution in general, but water damage is the truly fatal one). When I was a kid I could safely swim in Lake Ontario (our farm was on the shore) — now only 2% of the entire Great Lakes shoreline is considered safe for swimming. We're building desalination plants all along the North American shoreline because our inland water supplies are becoming undrinkable and cleaning the water is just not economical (and North America is far better off than heavily industrializing and unregulated pollution bogs like China — more).
I believe that if “everything else is OK” we can solve this problem with new technology and a lot (emphasis on a lot) of money. However, if we throw in too much war or economic instability at the same time, we will not have the resources to do this cleanup on a large enough scale. This type of environmental collapse could easily wipe out 90% of the life on the planet, and many scientists believe it's already happening.
Microbial Collapse
This one is the planet killer.
In very simple terms, if you make extinct the top of the food chain, everything else below it is largely unaffected (although the lack of predators does lead to destabilization downward to some extent). However, if you make extinct the bottom of the food chain, everything above it goes extinct as well. Microbial life is the very bottom of the Earth's food chain, and not only do we know almost nothing about it, but we're killing it off insanely quickly.
I've mentioned in past entries (more) about how food rots much more quickly now than it did in the past, and how farmed food has less nutritional value than wild food because of the microbial life it does or doesn't consume. To use the ocean as an example again (because as much as we land dwellers forget it, the ocean is the dominant biosystem on the planet), in the last twenty years alone (more), phytoplankton levels have dropped 30%. Planktons and other similar marine biota literally fuel (almost) all ocean life. If we kill the ocean (and our freshwater systems in parallel), we literally kill the planet.
