Future optimism scale

Knowing what I know about materials, their effect on ecology and people’s obsession with consumerism, I give humanity a score of about, oooh, 2.9. (and that’s me trying *very* hard to be generous and optimistic)

And you can subtract 0.1 from that number for every decade after that.

The trouble I see is that people are becoming more and more disconnected from what they buy. They don’t see the impact that it is having on other parts of the world. They don’t see any direct or local impacts, so some people even think “everything is rosy”.

On top of that, product life cycles are getting shorter and shorter and shorter, which is bad. We should be reward companies that sell timeless designs. Because there is less of an environmental footprint if you manufacture the same thing without any changes. Every time a part changes shape, moulds also have to change, that is not good for the environment. And the manufacturing phase of synthetic products contributes more to pollution than their end-of-life disposal.

90% of people refuse to even talk about it, like the problems will all magically “go away”. Cat videos get more likes on social media than most current environmental issues. And I find that to be quite saddening.

I don’t even think climate change or overpopulation is the biggest threat. It’s probably land clearing. We’re not even giving nature the chance to recover! If urbanisation continues, there just won’t be anywhere for other species to go! And it has been said that if insects disappear, we will soon follow. I think a greater threat to humanity is a mass extinction.

People should try to realise that if you put a great big hermetically-sealed dome right over the top of Manhatten, for example, it probably wouldn’t even work, because central park does not produce enough oxygen, and there is not enough space to grow food and get other material resources…

Probably the worst thing of all is the collusion between government, politics and business. The wrong people are being the most rewarded.

It’s not even 2100 that people should even worry about. It’s the centuries that follow that. With the current rate of deforestation, it’s not going to be a very fun world to live in…

Do keep in mind, I give [some] other species a much higher score than us, many an 8, 9 or even 9.9999 for some. But unfortunately, many many others (mammals and amphibians) will be, like, 0.1, 0.2 or 0.3. That’s really how bad it is. There are species out there with only a dozen specimens in existence.

I think I just cured myself of “gear aquisition syndrome” (GAS).

A strange thing happened to me today. Desire left my body.

A B&H catalogue duly/dutifully (pick whichever word you prefer) arrived in the mail. Even though I never ordered one. I thought I would open in anyway. If only to separate the polyethylene plastic covering from the paper so that I could recycle it properly.

Now I will admit that one of my past times is photography. And about the only money I spend these days is on food, clothes and work stuff…

Nevertheless, I am living in the first world. And first world people are told to buy. To consume. We’re hardwired for it from birth. From before birth even. We’re not even born yet and there are presents waiting for us. As we get older, they make “infant sized” shopping trolleys.That’s how bad it is.

So I obliged and flicked through the thing. All 340 pages.

I know enough already to avoid catalogues at all cost. Because they make you want things. Unecessary things. Here are two great articles, one and two, on how to cure your GAS.

But this was my first B&H catalogue. My very first one. “Just a peek” I thought. “To see what’s new”.

Anyway, I was quite surprised to find that as I was flicking through the thing, there was not one item that I actually needed. And believe me, I looked quite intently. I looked at photos. I even scrutinised the product descriptions. More surprisingly, there was not even even one item that I  wanted to own. The desire was gone. Gone I tell you.

I am done. I am done with consumerism.

I know none of it will make me ‘happier’. I already know. I am happy now, in this instant, with what I have. Happiness is not an accumulation of possessions. It is a state of mind. None of it will make me more productive, either.

I did want a 24mm Nikon AFD lens. Because my 12-24mm lens is “too slow” at 24mm (being f5.6), fairly large, fairly heavy. And my next focal length autofocus lens up from that is 35mm. Because it’s ‘only’ about AUD$400. And I was so close to getting that a few months back. But you know what? I know, wisely, that if I get that lens, it will always be “just one more”. So I am going to stop right here. 24mm is still very wide, too wide, for a normal lens. And I have a small little 28mm lens. I have a 35mm lens also. So that is enough. Enough is enough. “!Basta ya¡” (enough already) as they say in Spain. “ya está.” (that’s it). “Ya bastante.” (another way of saying “enough already”).

I am done and I am happy.
I am done and I am happy and I just wanted to share that with the world.

“Who are you going to believe, me or your own eyes?”

Ok. I am sick to death of hearing people rubbish climate change at this very late stage. Especially by the people who contribute most (manufacturing/engineering).

“Who are you going to believe, me or your own eyes?” …. down here on the Florida coast, the water-line remains the same it was fifty (50) years ago. Same goes for southern California, the high tide line remains the same as when I lived there in the early 1950s … hello Al Gore? you remain 100% wrong. The first thing that needs to be done is to ban any and all lawyers from any and all discussions about CC. — David Hubbell

David, I see you are a clever bloke. Engineers are always spouting off about how the world couldn’t work without engineering. Well ok. Fair enough. But it wouldn’t work without science either.

I put my trust in engineers every time I cross a bridge or catch an elevator. And you accept that your computer ‘works’, don’t you? So people put their trust in electronics every single day of the week. And who studies that stuff? Physicists. Materials scientists. That’s who.

But do you people ever question the theory behind semiconductors? No, because that enables computers. Do you question anything else to do with science for that matter? It’s these very same science and technological advances and principles that have enabled consumerism to spawn in the first place. These are the same people who invented MRI machines for Pete’s sake! And yet deniers say nothing about electron theory, magnetic domains or PN junctions.

What am I saying? I am saying that I think it’s time we showed the same level of respect for climate scientists. It looks to me the ONLY reason there are deniers today is that it means you have to “give up” something. And that something is called ‘lifestyle’.

Personally, I think that’s why you are on the denying side of the fence. Because if you accept what is happening, suddenly you’d have to take a long hard look at your own career choices. Because they contribute, don’t they? And you don’t want to do that, so you have these pre-conceived ideas about the world

Kindly educate yourself on the CO2 composition of the planet Venus and it’s surface temperature. And to all my connections, this is the real problem. The social intertia. That’s what I’m tackling here. It’s time to call out the bullshit “personal observations” for what they are. Personal observations.

Zen and the art of minimalism

How can you (we) all go about buying less stuff?

I have bought many things over the last few decades. I started with bike parts, I was forever looking to build the ‘ultimate’ bicycle.

I have easily spent tens of thousands of dollars on bike parts of the last 20 years. But every time I got something new, I would lust for something even newer. The more I got, the more I’d want. It was pure greed and indulgence.

But looking back, some of my favourite rides (most of them actually) weren’t done on my most expensive bikes. Most of my favourite rides were made on relatively cheap bikes!

Whenever I see a product now I ask many additional things:

1. Where did it come from / how was it made? What was the the environmental cost of manufacture?
2. Will I be able to resell it, reuse it, recycle it or compost it when I am finished with it? (and the packaging)
3. Do I really even need it? Or do I think I just ‘want’ it?
4. What are the “false promises” being advertised?
5. Will the new item create extra ‘worry’?

The next time you go to buy something, stop yourself and ask whether you really need it. Never buy on impulse. Never! Wait. Put things in your ‘watch’ list. Meanwhile, look for the most sustainable or ecological alternative. If you still think you ‘need’ something after one or two months, by all means, go ahead and buy it.

Ever since I started doing this, I almost never regret anything I have purchased. [Read more…]

Our environmental footprint

carbon footprint

Most of the global economy is based on the idea of selling physical products. And if you’re not selling something yourself, your clients are people that do.

B I’ve noticed that in some environmental discussions and debates, Westerners automatically assume that their country is less polluting than poorer countries. I don’t think pointing the finger at China really helps. And here’s why:

I think our blatant consumerism in the West doesn’t compare favourably to the third world, because all of the things that we buy have a kind of “environmental footprint” if you like. And note that I’m not even really talking about CO2 emissions here (even though the US carbon emission per capita is 17.56 metric tons while that of China is ‘only’ 6.19 metric tons per capita). Carbon is not the only element on the periodic table although it is the one that goes into the atmosphere more than the others.

If China pollutes rivers or whatever making loads of stuff for the West, who is really doing (causing) the polluting? The chinese manufacturers? Or is the Western consumer demand for those products ultimately to blame?

My main backround if materials science. One of the more eye-opening subjects I found out about (in terms of environmental degradation) is called “extractive metallurgy”. Extractive metallurgy is the study of chemical processes that we use to extract an refine metals from their ores. Basically, in a nut shell, all materials have to come from somewhere. Ususally it’s either the Earth’s crust itself or sea water.

In most of the processes, you need either need huge amounts of electricity and/or high temperatures and/or huge amounts of other chemicals to obtain the desired elements and/or compounds.

For example, here is just one of the many steps in the refinement of germanium:

GeO2 + 4 HCl → GeCl4 + 2 H2O

In this step, the reactive gas chlorine is being used to make germanium more reactive. So chlorine, which is toxic, is used in one of the processes to extract the element germanium from its oxide. Okay.

And here is just one of the steps in tellurium refinement:

HTeO−3 + OH− + H2SO4 → TeO2 + SO2−4 + 2 H2O

In this step, sulfuric acid is being used to make tellurium more reactive. Okay.

And where are germanium and tellurium being used you ask? They are two semiconductors that are the basis for integrated circuits and other electronic components in all sorts of electronic devices. Not so good.

In fact, many other nasty chemical compounds are used in the extraction, refinement and manufacturing industries. Many others.

I’m not 100% sure, but I think the worst offenders are the electronic consumer devices, simply because they contain the most number of hard-to-extract elements. The harder-to-extract elements require more chemical treatment steps. That’s just one of the reasons why they these elements are so expensive (not just that they’re rare). In fact I can probably go so far as to invent a new theory, which goes something like this: “the higher the unit price of an element, the more damaging its extraction process is to the environment.” But I digress…

Here’s the thing. There are a lot of chemical elements used in computers and extracting them from the ground and processing them taxes the environment (especially when you consider all of the planned obsolesence we see today). Our current way of life creates more and more electronic waste that cannot be recovered or recycled (except perhaps the gold bits)

I recently asked a few questions on Quora and I’d like to share those questions and answers with you now. Listed here are some of the toxic chemicals and semiconductors that are used in electonic decices. Go on, take a look. Can you begin to see how big the problem is now?

The point is, nasty chemicals are used at all steps of the extraction and refinement process. We just don’t ever see them being used in industry. Oh but they’re there alright. They’re being used all the time.

Suffice it to say that if Westeners think they pollute the Earth less than a typical 3rd-worlder, in my eyes, they are sorely mistaken. [Read more…]
