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

November 6, 2016 — leslie dean brown

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.

I was worried back in ’92.

October 10, 2016 — leslie dean brown

Yes I first learned about “global warming” in 1991 or 1992.

I think I must have had a smart teacher for the subject called general studies, because she knew about this new topic and warned all of us. She probably heard all about it at the United Nations Conference on Environment and Development (UNCED) aka the Rio de Janeiro Earth Summit. I could tell she was concerned. I can still remember seeing the worry in her eyes way back then.

Also, like a lot of nerdy sciency kids, I already knew about the atmosphere of other planets (like Venus for example). And so I’ve known for a long time that there isn’t really anything (apart from biodiversity feedback loops) stopping this planet from becoming more like either Mars or Venus.

So I began making lifestyle choices back then, when I was 14 or 15 years old. I chose not to drive. I continued to ride my bicycle. I rode it everywhere. In fact I didn’t learn to drive a car until I was 28 years old. Not until I had to. Not until I needed to deliver a lot of bicycles for my business. But eventually, it all caught up with me again. It slowly dawned upon me that I was falling into the trap of becoming just like everyone else again.

We are supposed to be working for a better future. That is why we all work so hard. But if the future is going to be worse, what’s the point?

So now, after almost a decade of driving around, I’m slowly but surely weening myself off of it again.

Later, when I gratuated, I refused to work for oil companies. I was offered a very highly paid job investigating the steel microstructure of crude oil tankers. I just couldn’t do it. So I went straight back to university and did another 5 years there.

Climate scientists are saying now that we are in a “climate emergency”. Look, the coal industry in Australia is saying there is enough coal reserves to last another 365 years. Well okay. But if other planets are anything to go by, this world’s entire fucking oceans could potentially boil right off and disappear into deep space! Melting icecaps will be the least of our worries. Now, while that scenario is never mentioned by climate scientists, that’s what planetary scientists mean when they talk about “a climate system that is out of control”. Are people starting to get it now?

Now I still don’t think people even today fully realise the implications of climate change, 25 years later.

A word about forest efficiency

September 25, 2016 — leslie dean brown

Scientists are hard at working devising new ‘technologies’ that can strip carbon dioxide out of the air. There is even a prize for the most efficient inventions that can capture this carbon and put it to good use; twitter is abuzz with the hashtag #reimagineCO<sub>2</sub>. But you know, I already know that the most efficient, sustainable oxygen factory (that also happens to double as a carbon sink) is none other than a natural forest:

Imagine this robotic-like device that can adsorb CO₂ molecules at the ppb level directly out of the Earth’s atmosphere through a process of reverse-osmosis and then transmorgify those carbon atoms into stiff and lightweight fractal-laminar-nano-composite material that is 100% biodegradeable, 100% compostable and 100% renewable! Once the carbon dioxide molecules are split into their atomic components, one of the only gaseous waste byproducts is diatomic oxygen²!! It gets better. It’s solar powered, of course!!! And believe it or not, but it uses *self-assembling technology*!!!! Really — this thing, it just unfolds itself to the final shape in front of your very eyes!!!!! Literally all you do is wait and let it do its thing!!!!!! And did I mention that it is self-repairing? Meaning it will heal its own damaged components!!!!!!! It’s that simple!!!!!!!! And it works!!!!!!!!!! It actually works!!!!!!!!!! This incredible machine, okay, will keep on going even if sections of it are completely hacked off!!!!!!!!!!! And it is like a 3D printer, so it will literally print practically unlimited copies of itself!!!!!!!!!!!! I am going to be the world’s first trillionaire!!!!!!!!!!!!! I have almost lost count of how many exclamation points I am using here!!!!!!!!!!!!!!!! ²And if you’re paying atttention, even the fineprint is good—the only other byproducts are aromatic hydrocarbons that are shown to enhance mood levels in the general human population.

I might be wrong about this but I’m willing to bet that the more biodiverse a forest is, the more carbon it can absorb. Simply because a dense tropical rainforest has more biomass than a ‘monoculture’ crop (soil is another matter).

So. We already have the ‘technology’ in the form of trees. All we have to do is reverse the landclearing. That’s why when someone tells you the best advice they can give is to “plant a tree”, they are almost certainly correct.

What’s new with GMO?

September 24, 2016 — leslie dean brown

Today I’m going to do things a bit differently.

I‘d like to encourage my followers to read several articles I just found out about. So here are several interesting pieces of news regarding CRISPR, a new gene-editing technique and a couple of links to the first ever completely synthetic, artificial cell:

Please read all of the above articles and educate yourselves. This isn’t in the mainstream news, but it should be.

I should probably state here that I don’t even pretend to know about genetics. I’m not a geneticist, I studied Materials Science.

All I do know is that nature has laws and you cannot break those laws. Bacterial diseases are lifeorms too and they are just as robust and ‘innovative’ as even the cleverest of humans.

I think that scientists often tend to overestimate their own intelligence level, and at the same time, underestimate the resourcefulness of nature itself. I don’t think we can ever fully predict the “revenge effect”. But it is there. The risk is always there.

I’m sure the field of genetics is really, really advanced by now. I’m not saying that it’s not. But the big worry for me is just that— as science becomes more and more and more specialised, people get ‘cleverer’ but they don’t always become ‘wiser’. So to put that another way, the greatest geneticist minds may claim to know all about genes, and they might even be right, but then they cannot also be the greatest experts in ecosystems. The fields of science are that big today that no one can know everything. It’s impossible! That’s the big worry.

“I don’t think it represents the creation of an artificial life form,” said biomedical engineer James Collins at Boston University. “I view this as an organism with a synthetic genome, not as a synthetic organism. It is tough to draw where the line is.” [source]

Some perspective about colonising the planet Mars.

August 29, 2016 — leslie dean brown

Illustration by leslie dean brown. © 2019. All rights reserved.

Imagine if 7 billlion people had always lived on a dust-bowl Mars-like planet with no life outside of the base stations. Imagine if that’s the way it had always been. Imagine if that was humanities’ entire existence, on the red planet…

With that in mind, I’d like to do a little thought experiment. I want you to imagine what would happen if we were to start exploring the solar system, from our home Mars.

The closest other world, Earth, looks very promising. We’ve spent a hundred trillion dollars on this latest space mission, okay. It’s been 30 years in the planning stage alone…

So we go to this new place called ‘Earth’.

And we don’t find another dust-bowl freeze-your-arse-off planet with no oceans, a toxic atmosphere* and a severe lack of oxygen. We don’t find it to be uninhabited. We don’t find the gravity extremely off-putting. We don’t find a desolate, barren wasteland devoid of all life like the home planet. No.

Instead, what we encounter is another world no unlike this one, the one we already know as ‘Earth’, exactly the way it is now, but without all the humans. Without any civilisation.

Imagine if we found 60 amur leopards, 400 Sumatran tigers, 880 mountain gorillas, 1826 giant pandas, 4080 snow leopards, 4848 black rhinos and 10000 blue whales!

Impenetrable jungles! Countless species of insects! Fish! Crustaceans! Molluscs! Birds! Frogs!

“Frogs? What an unusual name. What are they? Oh they’re slimy but harmless critters –amphibians– that thrive both on the land and in the water and use jumping as a form of locomotion.”

Lakes containing fresh water! Glaciers! Too many animal species to list!

“They’ve got a whole interconnected web-like thing scientists are calling an ‘ecosystem’ over there on that other planet. We’ve been trying for close to a millenium to get something like that going over here.”

Meanwhile back on Mars inside our dry and dusty base station, we get a breaking news report about the existence of all these weird and wonderful creatures on the new world. That’s right. Millions upon millions of new species that had never been seen or even reported before and now, as if by magic, all of a sudden they existed! Imagine what the news media would say if that was what we discovered when we weren’t even expecting the most modest and basic life-forms!!

Don’t you think we’d want to “swap planets”?

“No? What do you mean she is still not convinced of going?!

Because on the new planet they have oceans! Water falls from the sky! Food is abundant!

“Mate! You sure you still don’t want to leave here? They’re saying that not only could you breathe without a respirator, but everyone could literally walk outside, without ever having to wear a space suit. Your body would never be at risk of ‘exploding’! No airlocks required. A-fucking-mazing. I’d like to live there. Fuck this Mars shithole I say.”

But they’re not on that other planet, they’re right here on this one, now.

So just imagine if, miraculously, we materialised over there on the new and way cooler planet Earth with lots of life. Yes. Imagine if we didn’t even have to travel through space to get there; no need for a mass-exodus from planet Mars to get over to planet Earth.

“I’m telling you it turns out we don’t even have to travel anywhere Duncan! We’ve all been part of a cruel social experiment. Everyone has been living in a dream world. Just step outside and take a look for yourself. Its all out there”.

Imagine if we just found out about all that’s here, today. Imagine if it was only yesterday that we were totally ignorant and only today that we all just found out about all these new and never-before-described animals.

Giraffes, chameleons, snails, dragonflies, bees, grasshoppers, stick insects, jellyfish, toucans, macaws, catepillars, hermit crabs, barnacles, sharks, barracuda. Not to mention flowers.

Wouldn’t that be incredible? Wouldn’t that thought give you an unbelievable feeling inside? Do you think that would give us some sense of hope that “all is not lost”?

Next, I’d like you to imagine if we were given a second chance at everything. A chance to do things right. Imagine if, despite all the well-documented mistakes we’d made in the past, we were somehow expunged of all of our “conservation inaction guilt”. Imagine if we had a chance of recolonising this planet Earth. Do you think we’d be so naive and myopic as to make the same mistakes all over again on the new planet? No I don’t think so.

I think we’d all say something like:

“no hang on, we tried internal combustion engines on that other planet Earth and it didn’t go so well”.

I think we’d probably be a little more prudent the next time around don’t you think?

What you’d like to hear me tell you is what we could and should be saying:

“Yes we already know from our land survey data that there are plenty of coal & oil reserves on this new planet Earth. But knowing what we know about the alternate timelines, sooner than dig all of these fossil fuels out of the ground and burn them, we’d be better off building massive solar power stations instead. Better to utilise electric cars and have them recharged with renewable energy…”

Wouldn’t you agree that the new Earth colony could very easily put a government mandate in place that prohibits the use of fossil fuels and other toxic materials?

But that’s precisely what we are not doing, isn’t it?

Because we’re waking up every single day hoping that this problem will all just somehow “go away” all by itself.

We’re waking up every day with this second-chance-option, every single day, and we’re not taking it.

We already know that many animal species are threatened with extinction. Many people find this news very depressing/distressing (myself included). But they’re not extinct yet. No not just yet. I don’t mean to say that they won’t ever become extinct. I’m not saying that at all.

Last of all, imagine if we learned that instead of thriving on this new planet, the survival situation for quite a few of those species was more than a little precarious. Many of them are doing okay and still breeding fine but some niche species aren’t coping very well at all.

Now imagine we’d spent all that money to get to this other planet, one hundred trillion dollars, and then imagine we’re too fucking stingy to save even a few of the thousands of endangered species. What do you think would make news headlines on that day?

My point is, we haven’t even spent a hundred trillion dollars on some ridiculous space mission. Not yet.

Rather, it’s more a case of “they’re already here and we’re already there”. That new planet is this planet.

So to me it looks like the majority of humans are either stingy, lazy, stupid or a combination of all three. Most people have this “can’t be fucked attitude” about a problem we ourselves created.

We’re not stingy when we’re buying the latest generation mobile phones though are we? No, it seems we all have plenty of money for that.

See, I think we’re acting worse than a typical teenager who doesn’t want to clean up their own mess. They expect that someone else will do it for them.

But we’re not teenagers. We’re adults. And you’d think that we would have more responsibility for our own actions.

Instead, we’re treating dear planet Earth a bit like our first proper girlfriend or boyfriend —the one we used to hold on a pedestal, the one we looked up to, the one we tried so hard in the beginning for, the one we never imagined would end— and by foolishly and repeatedly not respecting the others’ limits and boundaries, we inevitably lost them. We then suffered the unimagineable heartbreak of the completely avoidable relationship breakup.

So in this rather unusual post, I’d like to remind everyone that we are taking what we have here for granted. Massively so.

We’re making the same mistakes we always make. And it really makes me rather sad. I feel like I shouldn’t even be living in this timezone…

Because scientsists are warning everyone, the entire world, that we might not even be able to recover from this particular “relationhip breakup”. It’s going to be far worse than our first-ever divorce. It’s going to be that hard and way harder still.

I don’t think we can make it on our own. I don’t think we’re ‘smart’ enough.

We still need this world. And I hope this blog makes people aware of that.

The way I think of it is this. Mars is just another example of a ‘shithole’ (meaning uninhabitable) planet in our the solar system. Why do I say that? Well I don’t see too many 5-star resorts being built in the middle of a deserted wasteland thousands of miles from civilisation. No. See, we already know that there’s this consensus that the nicest places to be and more importantly stay at are generally the ones where there’s either a city, a river, a lake, an ocean, a beach, a mountain or a forest. Or preferably combinations of them.

Mars has none of that. Who the fuck is going to want to voluntarily live there? Slaves? Miners? People with no imagination for what it’s actually going to be like living there on a day-to-day basis, sign some contract and get stuck there? Poor people who can no longer afford to live on Earth. Probably the latter. Maybe this is what this is all about. An ultra-rich class of people wanting to find a new home for all of us poor people.

Forget Mars. Earth is where it’s at. We’re already on the good planet Elon. If you want to go and live there, by all means, go. I think you’ll be back. You’re realise it was a bad invesment
