Finally. ETA is finished!

Of course graphic designers, typographers and illustrators could forsee their demise a long long time ago. This is what happens whenever any organisation decides to embark on a hand-drawn, #DIYlogo.

Why am I a minimalist?

—

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…]

The true value of soil

Food practically grows all by itself on planet Earth.

Let me ask you something: do we actually ‘make’ our own food? Do we? The answer is “no we do not make our own food”. We just throw pre-existing seeds in the ground and make sure most of them get enough water to sprout. We don’t make it from first principles; it grows all by itself from the soil! We simply harvest that food (once it has already grown).

Let me ask you the next question: do we humans ‘make’ soil? Not can we make it, do we make it? Again, no. Bacteria, worms and insects do that for us. Sure we might put organic matter such as apple cores, banana skins and orange peels onto the old compost pile and think we’re making

loads more soil. We might even throw things like paper and cardboard onto our compost as well and think we’re creating heaps and heaps and heaps of soil.

We certainly tend to the plants. We avoid flooding unless we’re growing rice. But what I think humans really do is collect, store and distribute food. If we had to do all of that for 7 billion people, for 7 million people, for even 7 thousand people, with no air, no water and no soil to begin with, I think you’d see scientists really starting to scratch their heads. Can’t be done! It just can’t be done.

But are we? What are we really doing? Once gain, where did that apple core come from? Where did that banana skin come from? Where did that paper come from? Where did those trees come from? The chances are you’ll find that most of it wasn’t hydroponically produced (using liquid fertilisers and zero soil). Was it? No. It was mosty farmed, from pre-existing soil. And I’m guessing that that soil, ladies and gentlemen, took thousands and thousands and thousands of years to form.

So is it any wonder that farmers commit suicide, when they tell us that the quality of soil is falling?

In other words, we’re not somehow magically separated from nature. Scientists are never really able forget this. If seven, eight, nine or ten billion people want to live on this planet for more than a few centuries or millenia into the future, then we’re going to have to re-evaluate our values and our priorities. I think it’s time we refocus our efforts on Earth (even Carl Sagan’s last book, pale blue dot was as much about Earth as deep space and look how ‘into’ deep space adventures he was). Going to Mars is not a viable option.

And so you might say: “well okay, I know people that actually eat 100% hydroponically-grown foods, I’ve seen it”. And again I ask: but the people who made the hydroponic setup, did they also get all of their food from hydroponically grown plants? What about the people who made all that fertiliser? What about the people who built the whole darn fertiliser setup? What about the people who transported all of the above? And what about the people who built the vehicles so that all of that lot could be transported? Did they all eat hydroponically grown food too?

Is everyone in that hydroponics industry only eating 100% hydroponically-grown foods? Short answer? No. So my point is that at the moment, even if we can hydroponically grow a bunch of food, it’s being heavily, massively subsidised by nature.
