Why am I a minimalist?

March 31, 2017 — leslie dean brown

I am a former materials scientist. The first question I always get asked is: “what is that?”.

Materials science is the study of mostly synthetic materials such as metals, polymers, ceramic and composites. We study their physical & chemical properties and how they are extracted from the Earth.

I am telling you this because I think that people need to start listening to scientists. More people need to listen to more scientists.

That’s a two way thing. I think that more scientists should start their own blogs (and other mediums communication like that).

Right. So I am a former materials scientist. And do you know what I now think about materials? What I now know?

I think that everything that you buy kills some part of the world somewhere else. The metals in the electronics that you are buying come from mines and natural spaces have to be destroyed to get them. I think we have to realise that and remember it every time we go to buy something. We need to think about that whenever Apple tries to sell us some new product. Do we really need it? What is the environmental cost?

My view now is that the things that we buy have to come from somewhere. Ask yourselves where. Most plastics [polymers] in use today come directly from oil. Uh oh.

All metals that aren’t being recycled are mined. Mines are always built in the natural environment (just look what happens when they are not –like with coal seam gas– people complain their heads off and usually get their own way).

But the problem isn’t just big banks and mining companies. Because I think 99% of adults have simply forgotten where they get their stuff from. [Read more…]

Future optimism scale

February 24, 2017 — leslie dean brown

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.

Corvette owner defends his purchase…

January 10, 2017 — leslie dean brown

“A guy looked at the Corvette the other day and said I wonder how many people could have been fed for the cost of that car. I replied I am not sure, it fed a lot of families in Kentucky who built it, it fed the people who make the tires, it fed the people who made the components, it fed the people in the copper mine who mined the copper for the wires, it fed people who make the trucks that haul the copper ore. That’s the difference between capitalism and welfare mentality. When you buy something,you put money in people’s pockets and give them dignity for their skills” — Anubhav Krishna

Yes that may well be true, but I say again, if everyone on the planet owned as many corvettes/helicopters/mansions at they wanted, for as many generations as they wanted, Earth itself would be really fúckéd (not the people, the planet).

If you understand all about the materials that go into your car, as you seem to, then you will also understand this. It all has to come from the Earth’s crust. So nature is what is getting fúckéd over here, not people. I say this as a former materials scientist. Perhaps a more relevant question should have been “what was the environmental impact of this car?”.

The real trouble today is that this capitalist/industrialist model is not at all sustainable in its current form. Just because it has ‘worked’ for a hundred or so years, doesn’t mean it will ‘work’ for another thousand (it won’t, it can’t). Apart from that, I find it SAD that people equate materials with success.

Take a look at this latest graph.

December 7, 2016 — leslie dean brown

Go on, have the balls to actually look at it:

See where we are? We’re right at that point where we don’t want to be. That’s where we are. The appropriately red-coloured line that is beneath all the others (well beneath).

Look, I don’t claim to know much about climate science. I know about materials science. But if there’s one thing scientists know how to do, it’s to respect others’ areas of expertise. Especially the expertise of other scientists.

It’s a bit like the song:

“What you don’t know you can feel it somehow” — U2

We know that there are others who are cleverer than us. And we respect that knowledge.

So I admit that I don’t know how the Earth’s climate fully works. But this latest graph worries me. This graph worries me a lot.

Because its pretty darn obvious to anyone what is going on in this graph.

I don’t think the Earth is completely screwed just yet. But if we don’t change NOW, then it will be.

I think the Earth’s climate is remarkly resilient considering all we’ve thrown at it over the last century.

But all I know is, if man thinks he can change local environments —on a global scale mind you— without global consequences, well then he is sorely mistaken.

That is not the way this world works. That is not how any world works.

Because this is the graph of all graphs. This graph should be printed on the insides of all petrol tank lids.

Every time you wish to use your car, you should be thinking of this graph!

Every time you want to fly somewhere, you should be thinking of this graph!

Every time you eat meat, you should be thinking of this graph!

This is the “climate emergency” graph that James Hansen is referring to.

And what do I see? In reality? In reality, I look around today, and I see bugger all people talking about this problem. And yet it is a big problem. A very big problem.

People should be talking about this over their lunch break and their coffee break. And for some reason they’re not. They’re just not.
