Who are the greenest printers in Australia?

August 15, 2016 — leslie dean brown

I just finished a diploma of graphic design a few months ago. And during a subject called “prepress”, I found out that printing is not the most ecological part of graphic design. In fact traditional printing is not very good for the environment at all. It isn’t all just about the paper they use, but they also use loads and loads of metal printing plates and lots and lots of water.

So I have been shopping around for the most ecological printer for some time now (like 6 months, on and off). And I think I’ve finally found a quality one that is reasonably priced. [Read more…]

The problem with using biofuels in aviation.

July 31, 2016 — leslie dean brown

Recently on LinkedIn:

First, it’s a premise of sustainable, alternative fuels that their production actually draws down atmospheric carbon–the carbon comes out of the atmosphere to make the fuel. The carbon is released again when the fuel is burned. By (albeit partial and imperfect so far) application of that principle, vastly lower net emissions (on the basis of life cycle analysis) are now possible.

I understand all abot life-cycle assessment. Yes, true, biofuel crops do take CO2 out of the air.

But not if brazilian rainforest has to be cut down to make way for new plantation crops — because the native forest already does a way better job of taking CO2 out of the air than a crop with less biodiversity ever will.

So my question is: where are we going to grow all of the new crops that will be needed for this additional biofuel?

It’s no good saying that new sustainable crops will reduce the CO2 from the air if you harvest the whole thing every year and burn it again. That only releases the same carbon that was absorbed by the crop in the first place… so no net CO2 increase. (well that is probably an over-simplification, because some carbon dioxide no doubt goes in to the soil) [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)

This is Pluto speaking here.

>sign the petition to reinstate Pluto‘s full planet status<

Hello.

This is Pluto speaking here.

Look, I wasn’t very happy when some scientists took away my “full planetary” status in 2006 without even consulting me directly. And I’m not alone.

I’ve been thinking about it – and this whole ‘dwarf’ designation has never really sat well with me ever since. And my moon Charon is not to thrilled about it either… because that would make her the moon of a dwarf planet, aka a “dwarf moon”.

Especially when you say that I’m a dwarf planet, and then go on to say “which is not really a planet”. Imagine how Jupiter would react if you said: “Jupiter is a gas giant planet… which is not really a planet!” !!

And then you gave me a number. What do you call it? “Minor planet designation”. Wait a second. Let me look that up. Let’s see here, what have I got, I knew I had it somewhere… “134340”. That’s it. “134340”. That doesn’t sound very special to me. One minute I’m named after a God. And the next thing someone has placed this completely arbitrary bogus number IN FRONT OF my name. Not after it mind you. BEFORE! Like this: 134340 Pluto. One-three-four-three-four-zero-pluto. To a planet, this is invective! [Read more…]

Hope for the planet

March 26, 2016 — leslie dean brown

I went to David Suzuki’s “hope for the planet” talk last Tuesday and I am feeling inspired! I think it was worth going, if only too see so many like-minded individuals in the one place at the one time.

Towards the end of the discussion, one young attendee said that she saw the audience as “agents of change” and asked what the single biggest piece of advice that the speakers could give to the audience. And Naomi Oreskes answered that particular question; that she couldn’t give one generic answer, because it all depends on our field of expertise. I thought that was very wise. And so I am using the tools at my disposal:

I might as well use this opportunity to tell the whole world that like David Suzuki, I too find it COMPLETELY OUTRAGEOUS that people put the economy over and above the environment. Without the natural environment, there wouldn’t even *be* an economy!

I want people overseas to know that Gina Rinehart spent $22million on a campaign to destroy the carbon tax in Australia in 2010. She went on to invest $200million in network ten and another $280million in fairfax media to sway public opinion. Luckily she has sold most of her media investments in 2015 and has stopped trying to become one of the members of the board of directors…

I think that was a despicable attempt to control the media and thus sway public opinion the proposed carbon tax, which would have hit the mining industry hard. I see her attempt to buyy out the media as a form of environmental corruption. Inn fact last week I invented might have a new term called ‘EC’. EC is a term that originates from PC (which means politically correct). You probably already guessed it; EC means “environmentally correct”. So I think that Gina Rinehart may well be the richest person in Australia –or the richest woman in the world– but she is just not environmentally correct.

Oooh yes I think that the carbon tax should definitely be reinstated in Australia. Most definitely!

The trouble I see is that this: we know the extra carbon dixode we are putting into the air comes from burning the fossil fuels such as coal and crude oil. So if we have to reduce the amount of carbon going into the air to the level before the industrial age, not only will we have to put back all the forests as they were before all of the mining (to restore the original carbon cycle), but we’ll also have to find a way to offset billions upon billions of tonnes of of carbon that have been mined and essentially burned into the atmosphere. Hmmm
