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…]

Take a look at this latest graph.

December 7, 2016 — leslie dean brown

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

nsidc_global_area_byyear_b-800x533

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.

A million people on Mars by 2060?

September 29, 2016 — leslie dean brown

Really? Why? Aren’t there enogh bloody people in existence already?

I like Elon Musk. I really do. But I think his whole mission to mars is totally misguided. I think the best way to invest in humanity’s future is… by creating longer-lasting protection for the last remaining wilderness areas. If that is what leading biologists say we should do, then that is what we should be doing!

I think he’d be better off buying up a huge chunk of forest somewhere and just… leaving it intact. No human intervention. Or, if he must ‘build’ a structure, design a bloody great hermetically sealed dome over the top of the canopy, and just lock people in there for five or more years. It’d be cheaper, better for this planet.

How many emissions do those rockets make? How many emissions do making the rocket parts make? It’s just totally a waste of time buggerising about terraforming mars when we already have a terraformed planet here with millions of more naturally occurring species on it.

Technology got us here in the first place, it won’t save us now. The only thing that can save us now is … not clearing any more new land, increasing the size of existing wilderness areas. And planting lots and lots of trees all trhoughout suburbia.

Zen and the art of minimalism

September 10, 2016 — leslie dean brown

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…]
