What this scientist thinks of NASA’s 2035 mission to Mars…

May 11, 2016 — leslie dean brown

The 2035 Mars space mission is said to cost an estimated US$1.5 trillion.


What are my thoughts on this? That sounds like an aweful lot of money to me — to keep four to six people alive on another planet— in my view it’s money that could be put to far better things, like keeping 7 or 8 billion alive on this one.

To put things into perspective, it’s the equivalent of spending 94% of Australia’s Gross Domestic Product… for what? A dozen or so people to have the trip of a lifetime… at the most? That’s one hell of an expensive postcard!

If I personally had US$1.5 trillion dollars to play with and I wanted to ENSURE the future surivial of the human race, why, do you know what I’d do? I’d buy up all the wilderness areas up in poorer countries. I’d abandon that silly space mission. That’s what I’d do. And this is coming from someone that liked reading Carl Sagan’s cosmos… [Read more…]

Open letter to climate change skeptics (from a scientist).

May 9, 2016 — leslie dean brown

Do you notice the terminology “global warming” is somewhat detached from the humanity that caused it? As if it were the planet’s response to our domination, but not directly our own fault.

For me, the notion that this is all some part of a repetitive ‘prehistoric cycle’ which man has nothing to do with is preposterous. It just happens at the same time man enters the industrial age, and is happening 10x quicker than anything before. Hello! coincidence!! The words rate of change have very strong meaning in the scientific community. Grand geological transformations don’t just happen over a matter of years or even decades. They are supposed to take millennia, or longer. So now that the average global sea & air temperature has risen a degree already, I think we’re already in deep shit my friends.

Deforestation today proceeds at 55,630 to 120,000 square kilometres each year. At this rate, all tropical forests may be gone by the year 2090.

You might be one of the smart ones & think that the Earth’s volume is vastly superior to what we could possibly be doing on the surface. But the surface is paramount; everything that happens here depends on it. Yes, the atmosphere has the capacity to change the temperature of the entire planet and it has done so before. Still don’t believe it? The temperature and composition of the atmosphere are dynamic factors; they do not remain constant. Note I deliberately used the term “the atmosphere” because it is most definitely NOT “our” atmosphere! Look at the atmosphere of Venus: it’s completely hostile. Look at the atmosphere of Mars: there is none. No one said to us “The Earth is going to remain habitable/hospitable for as long as you lot are around you know”.

I think the real reason why some people continue to deny global warming is taking place (subconsciously or not) is that they can’t deal with reality. So if they convince themselves that it would’ve happened anyway, they can simply carry on life as normal, and not have to worry about it.

So I think the very least people can do is to accept that they’re responsible for it. Anyone who doesn’t think it is happening is worse than the flat-Earth society. Honestly. Just go bury your head in the sand somewhere, ostrich style. (see that’s what I like about a blog, I can use stronger language than a scientific paper and not have to be so damn subtle in writing and then have someone edit out my carefully chosen words)

What is the environmental cost of consumerism?

April 1, 2016 — leslie dean brown

“We’re very very disconnected from what we consume. So because of the widening degrees of separation between the consumer and the consumed we no longer have any real appreciation for the embodied energy, the embodied destruction, the embodied suffering that goes in to every stage of the supply chain in the things we buy.” — Mark Boyle

I‘m sure that most consumers don’t care less what chemical elements are used in the manufacture of all the products that they buy. I’m talking about all the elements and compounds required to make all of these products function like they do. But consumers should care. We should care about what products are made of, what they are made from.

But with things like consumer electronic devices, customers simply don’t think about their ‘ingredients’ much. I think the problem with this world today is that consumers don’t question the true origin of synthetic materials, let alone how they are extracted and processed.

I think people really need to wake up and ask where their materials are coming from, learn about all the many processing steps each material requires (extraction, refinement, manufacturing, production) and also ask what happens to all these materials at the end of the product’s life. In many cases, even with recycling of plastic/paper/metal, the majority of materials on the periodic table aren’t being recycled and are ending up in landfill (and/or the ocean).

I think each product sold should have an ‘ingredients’ label showing exactly what materials are in it. That way, people could [eventually] reference which materials have the highest ecological impact…

The obvious exception is of course food. Wherever food is concerned, then consumers quite rightly want to know what they are consuming. We want to know all the food ingredients. We want to know what we put into our bodies.

Recent research on global warming, sea level rise and super storms.

March 24, 2016 — leslie dean brown

If there’s one video I think you should watch today, it’s this one.  I think climate scientists in particular have a special “duty of care” to humanity. I wholeheartedly suggest that all climate scientists boycott fossil-fuel powered cars in keeping with their discoveries and the changes we all must start to make on an individual basis. I think it may show the general public that they are prepared to make some sacrifices for what they believe in.

As I stated previously, I personally no longer own a car — but I do use (borrow) a car about once a week now. Since I sold my last vehicle, I am able to donate more money to environmental charities with the money I save on fuel, insurance, upkeep and everything else… I have actually donated more money to charity than I have spent on fuel so far in 2016. I think more people need to do that.

I really don’t think it’s wise to put all of our trust into current politicians. I firmly believe that most of the mainstream parties do not have our own long-term best interests at hand. I also think that the two very traits that have put us where we are today, namely, our anxiety and what I like to call our “social intertia”, may well be our undoing as a species.

Why I decided to quit facebook.

March 17, 2016 — leslie dean brown

In recent news, I just quit facebook. I quit because they are encouraging trophy hunting by allowing their pages to remain online. I believe they could do so much better with animal rights and conservation issues.

Nothing happened. My head didn’t fall off. I enjoyed real life more now. I am happier and much more productive.

I have even started this petition to get more people to quit facebook as a form of protest and defiance.

Mark Elliot Zuckerberg,

The first time I logged on to the internet, the year was 1995. I had to go into a special room at university to access it. Only about 30 computers were connected to the internet for students to use — in the whole university.

A few years later, more rooms appeared throughout the campus. I remember one day in particular. My college buddy could only find a handful of Porsche images *on the whole internet*. I can even remember him printing it out. It was so rare to him it was like a prize. I remember because we had to take turns — using the same internet connection!

Four years later, in 1999, I got “into trouble” for using the internet at work! Yes. “People can see you” he’d say. I had to show my boss that I was searching for material properties online. He promptly wheeled his office chair over. He had called my bluff. And I pointed to the screen. “See?” At that time, people didn’t use the internet for work. No.

I don’t know when it was exactly. I was still at university. All I can remember was that the internet was still fairly ‘new’. The average person still did not use the internet on an hourly or a daily basis (except for email). Anyway, I got this weird “friend request” from this unknown person calling himself “Mark Zuckerberg”. It wasn’t one of my friends. I’m pretty sure it was actually you.

If memory serves me correctly, Mr. Zuckerberg, you actually came to me. I certainly never went out specifically looking for anything like facebook, because I was a nerdy anti-social science graduate. You probably found my email or something.

I decided to accept your initial “friend request” and sign up to this new facebook thing. And because I was introverted and shy, I never really bothered to say anything to you. It was when there was only a few thousand facebook members *in the whole world*. At the time I can remember thinking:  “what harm can it do?”. Nobody I knew had a facebook account. I repeat: nobody. And so it began…
