Dogs don’t believe in global warming. Of course they don’t, because they don’t give a shit. So why should we? About 27,000 years ago, domestic breeds of dogs began to emerge from ancient ancestors of modern wolves. It is thought that “gentler” wolves that were better adapted to human activity and were able to acclimate themselves to us were eventually domesticated and bred into the many breeds we know today. It’s hard to believe, but Pomeranians and Rottweilers have the same genome, and they are genetically more similar than the between six and 11 distinct giraffe species. I mean, I look at a giraffe and I think, “giraffe”. It’s a little hard to accept that a chihuahua can’t be a different species from a mastiff, but okay.
I have to admit to my anxiety over hearing increasingly grim news about how humans may be “the asteroid, not the dinosaurs” in the assertion that we are not just looking at – but may be part of the problem in the Sixth Mass Extinction in earth’s long history, according to the Daily Beast. Well, this isn’t such a new idea. Apparently, Charles Darwin entertained such an idea in The Origin of Species back in the 19th century. Yet this is just as hotly debated as it ever was, and Americans seem to be polarized over this issue. But to me, it’s a simple question of whether humans could possibly have ever made lasting changes to our environment. The argument against this position maintains that there are many factors, and man is not solely responsible for the apparent change in earth’s climate, if it is indeed changing. To wit: many scientists agree that the earth’s average temperature is rising, as are sea levels. Ice caps are shrinking, and habitats are dwindling. Opponents have argued that there is not sufficient data to prove any of this. I call bullshit, but we can agree to disagree, at least until the next ice age. Apparently, some are willing to hold their breath instead of listening to reason, and they will not be convinced.
But here’s something interesting: dogs. Dogs would not exist if not for human intervention. The same may be said for cattle, pigs, cats, and chickens. Sure, there are wild varieties of each of these animals. But my docile, domestic Siamese cat in no way resembles his erstwhile wild cousins. I saw one of them, while mountain biking one October day. Ahead on the trail I saw a large cat, probably a bobcat. It was hunched over something it had captured, perhaps a rabbit. I slowed, and when it saw me, it picked up its prey and ran off into the forest. My cat would hardly be able to catch a bunny. His instincts might lead him to kill it, perhaps even try to eat it. But I doubt it. What’s the difference between my kitty and that wild predator I encountered? Human intervention. Anyone who thinks humans have not made dramatic changes to our planet has perhaps not been paying attention.
With this knowledge, you might think the human race would start paying closer attention to our impact on this planet. It behooves us to take better care of our environment. Is it going to prevent extinction? Probably not. But we should start taking more responsibility for our actions. We were taught that in kindergarten. Tell the truth, clean up after yourself, and share with others. Later in my life, a teacher and pastor taught me about stewardship. He said we are called to be good stewards over everything we’ve been given: our health, our minds and bodies, our relationships, our finances, and our environment. It was a surprising message coming from the church. But I appreciated it. I took it to heart, and I try to live by this philosophy. It’s a concept I’ve heard from others: we were not given this world by our parents; instead, we are borrowing it from our children, or something to that effect.
I was reading an article about the Observer Effect. The principle can best be described as one’s inability to precisely measure something without changing the conditions. For example, let’s say I want to know the temperature of a cup of coffee. The coffee in the cup may be 50ºC, near scalding. So I dip a thermometer into the piping hot liquid, but the thermometer is not already the same temperature as the coffee; thus, the coffee loses heat, and we can’t know what the temperature was before I started my test. In the real world, this would hardly be noticeable. But there are many examples where observing a system changed the results. I bring this up because it’s important to realize that small changes make big differences down the line. You can really see this if you’ve ever tried shooting baskets from the free-throw line. You can have almost the same posture and movement each time you shoot, but the results can vary dramatically. Humans have been making small changes for tens of thousands of years. Actually, there have been huge changes, like the extinction of North American prehistoric horses, or massive deforestation. Humans have been altering this planet’s trajectory, ecologically speaking, all along. And the earth may not be able to recover quickly enough. It wasn’t too long ago that the city of London was shrouded in pollution from coal fires. Factories around the world continue to spew God-knows-what from huge smokestacks. And rivers and oceans are choked with medical waste and toxic runoff.
So, I recycle a lot of household waste. Otherwise, I like to compost things that are suitable. The rest is garbage. We produce a lot of trash. I think I’ve posted about this before, but at least I delivered a speech about it recently. I tend to get a little preachy with this subject, but we all have our passions, I suppose. Is it too much to ask that I should be able to breathe clean air and drink safe water? I don’t take these things for granted, because there are places like Beijing and Flint.
Hopefully, we will not be on the extinction list. I wish we could say that about other organisms. But we can do something, small though it may be. We’re already making positive changes, and perhaps the planet will recover this time.
So the next time someone says we’re not responsible for climate change, ask him if he believes in dog.
