Diversity is important.
This sounds like the kind of slogan I heard growing up, trying to convince folks my age not to be racist (or at least not overtly verbally racist; I'm not sure if tearing down the underlying structure of white supremacy/heteropatriarchy was what they had in mind).
It's also foundational to how I understand ecosystems, evolution, and survival. People think of evolution's "survival of the fittest" as some sort of survival of an abstract best. Instead what it means is survival of the thing that best fits a particular environmental space, and of course the environment is always in flux. That means the "fittest" is always in flux. Think of the environment as a lock that's always changing; some keys may fit in easily and well, some you can kind of jam in there and make it work, and most just will not go. In this situation, with a lock that's always changing, you want the largest possible pile of keys to try when you need to open the door. Taking only the key that opened the lock yesterday, when you know it's going to change today, well. That's not helpful.
Maybe you're great at patterning and you think you can predict which key will be needed tomorrow, and the day after, and the day after. You probably still want some keys in your back pocket for insurance, and you probably want that big pile somewhere in reserve for next year, or for the year after that.
Opening the door is, of course, survival.
Diversity is the means for survival.
Life is pretty great at creating diversity. Sex, genetic mutations, and epigenetic and other non-genetic inheritances provide a pretty robust suite of tools. Life creates diversity, this diversity effects (is, really) the environment, and complicated niches pile up that allow even more diversity to form.
"We" (our current dominant society) is breathtakingly wonderful at eliminating diversity. This is not a great long-term survival tactic.
When I work with ecosystems one of the things I love so so much is being surrounded by those shades of difference. Not only do they convey information and give me entrance points with which to engage with the systems and do my work; they also feel good. When I am immersed in a complex system my mind feels at rest. Data collection and analysis are happening, often far enough in the background that I am not aware of them, and so I should feel... maybe overwhelmed, or busy, or apprehensive, or exhausted. Instead I feel stable.
This is why I ran away to live in the woods. I wanted to engage with living systems on a regular basis. I am tired of the capricious, arbitrary, and dead-end ecology of cities. I don't feel there is space for humanity in them, really, only an increasing self-absorption and then an end. Life will take over; they are an excellent niche full of microclimates and resources.
I don't think I can live in the woods without some kind of human society, of course. I'm maybe hopeful that society will come to embrace the importance of flexibility and using the ecological tools at hand rather than trying to impose a static form on nature. I mean really, humans vs nature: who will win? That's not even at question.
Now we're getting far afield, but I wanted to engage some background here. I wanted to pull in the enormous history of life, I wanted to bring the sense of future survival and my own reactions of peace and rest in the face of biodiversity into the light.
This is the context in which I say I love my pigs. My ossabaws are, well, they are a genetically distinct population. The population was feral on an island (Ossabaw Island, ha) in Georgia for quite some time. That niche was quite different from the places other hogs were evolving and the sea was enough of a barrier that the population became genetically distinct (instead of mixing with nearby hogs without those constraints and "swamping" that uniqueness). So you might expect a relatively small population to be very uniform.
I have four foundation sows and a foundation boar that, altogether, come from three lines of Ossabaws. I've had a total of fifteen piglets grow big enough to begin to notice how they're turning out.
The pigs are astonishingly diverse. The piglets are astonishingly diverse. I don't know how much livestock you see; quite often folks never really see animals raised for normal domestic use. My pigs are orange, black, white, and peach with spots and random splashes on them. Some are longer and some are rounder. Some are taller and some are shorter. Some get fat on less food and some are leaner. All are rounder than conventional pigs, with long noses and shaggy mohawks on which the tips of each hair are split like a little broom.
Originally I was going to keep the boar and the best 2 sows and eat the other two. But. They're so different. The babies are so different from each other. The sows are so different from each other. And there are so few ossabaws in the world; I may not be eliminating genetics forever as long as the person I got them from continued her herd, but there's a chance it could happen.
Humans, in that way they do, tend to select for useful traits. With pigs right now we select for length (more bacon), heavy shoulders, that sort of thing. When I save breeding sows I have a human tendancy: save what works best for me. Winter hardiness for sure! A little bigger maybe? I really like the apricot colours with spots...
If I do that for long enough then my own pigs become less diverse. They start to standardize into, not a landrace like the Ossabaws, but a breed. If my neighbour does the same but she likes black pigs and shorter ones, hers will also start to standardize into a different breed. Then maybe the diversity is not lost, but is separated out into two niches. Or, maybe the white colouring is lost over time.
So I need to be careful as a steward of these genetics. What am I selecting for, my convenience, or for diversity? Every time something doesn't breed I'm selecting *something* and if I'm not mindful of what, unintended consequences can occur. What genes will pigs in the future need if there are no more humans? What genes will future humans need in their pigs? It's hard to guess, so I need to try very mindfully to be diverse in my selections.
I believe it is important to have diversity, not only within species but among them to have a huge range of plants and animals that may at some point save us from a future we cannot predict.
And here's the thing, I love it. I love, inside my bones, going out and seeing the variations in shapes and colours. I love hearing the difference in vocalization sound and frequency. I love seeing different behaviours in different individuals.
It causes me to feel at peace.
