Did someone mention.....
*Agriculture?*
Some of you may have wondered what I was doing while I was away for so long. The answer is: learning about alternative modes of food production. I'm now in grad school for agronomy.
The bottom line is that yes, a human being, or any animal, must make certain demands on the environment around them for survival. All creatures do this, all creatures "consume" in this biological sense. Plants take up water and nutrients from the ground and store them in their bodies. Animals eat corpses of other animals or living plants and incorporate those molecules into their own bodies and derive energy from them. This is just the fact.
However, the real key to the ethical dimension of this is the question of necessity. So much of what modern humans do, in terms of our demands on our environment, on our fellow humans, on animals we raise, on wildlife, on ecosystems - is gratuitous, pursued for the sake of greed, domination, out of a bored emptiness or a gnawing fear.
Let's take modern agriculture. I know that anyone reading this is immediately going to jump down my throat and say "well I happen to LIKE _____(insert agricultural product that I'm about to imply is gratuitous)". Yeah well, whatever. We all like shit we don't need. We were raised that way. To some extent it's in our blood. That doesn't make it ethically defensible, and anyone with an ounce of intellectual and moral courage would admit that at least to themselves.
So, moving on. Think of all the crops that we didn't need to grow, didn't really need. Tobacco. Lots of cotton and other fibers that were made into frivolous clothes and other wasteful things that nobody even necessarily wanted that badly. So that's the non-food world, we could go on and on with just that. But even in food - how much chocolate does the world really need? How many avocados? How much coffee and tea? How many spices? How many ornamental shrubs and bouquets of flowers?
It can certainly be argued that even the most austerely wholesome life would leave some small room for minor luxuries like a cup of tea. I agree with this assessment. But it turns out that those little comforts can be almost always easily derived in a much much more ecologically responsible way, if the person in question will simply tolerate a bit of moderation and a slight change to the fairly cosmetic aspects of the experience.
Example: in the southeastern United States yaupon holly grows wild all over the damn place. It's native, but in a lot of disturbed ecosystems, especially those that have been cleared in the last century (Read: a huge amount of the South), and those that have been prevented from burning regularly as they had usually done in recent natural history, the yaupon begins to take over the understory and drive down plant diversity. Basically it becomes a bit of a pest.
Here's where the humans come in. We caused that problem. We can solve it, and replace a lot of tea plantations in Sri Lanka too. Yaupon holly can be made into a really pleasant tea with a respectable caffeine content, it was drunk by the natives of the area ceremonially.
That's just one specific example. And at any rate, could a lot of us stand to do with less tea and coffee and dessert anyway? Yes. I've recently stopped drinking coffee and alcohol. I don't miss either one. They're just addictions, and although I knew their pleasures intimately, turns out I don't need them. My quality of life is the same or better. Who would have thought. And when I really just want a mug of something, an herbal tea does the same job, and I can still frequent the coffeeshops just the same as I always did.
So it is with all the frivolities. If it is different, then they are not frivolities, are they?
And that's the answer to the question of how we can ethically live on this planet, without a catastrophically destructive anthropocentric mindset that Putin rightly critiques. Even if you are an anthropocentric through and through, you should agree with this prescription, because we are shooting ourselves in the foot. Turns out its all connected.
I can go on, but I've probably said enough already.
