Every student can make a difference

Graham Henton is an inspirational Enviro Science Teacher at Whakatane Intermediate School, in the Eastern Bay of Plenty. We talk about his background, his approach to teaching and the restoration of the Awatapu lagoon and why he loves what he is doing.

Talking points

What a difference a child can make

Every child – I believe in you

Understanding – what we do as human beings

Interdependence is everything

If you don’t like Enviro, come and talk to Mr H, what’s going worng, what am I doing wrong?

Too many takers and not enough givers

I’ve made up a word for people who are selfish: BigISpoilers – their mission in life is to spoil things for everything and everyone else. I encourage the kids to be enviro-kids, and they are going to assist the planet to be sustainable.


Empower their life of making a difference

Put your cards on the table, lets figure out what we can do

Why would you want to cultivate a culture of extravagance?

They’re doing it, that my legacy.

It buzzes me out, I met people all over NZ, big burly fellas at the petrol station, “Mr H you believed in me”. I empower kids to make a difference. I want to empower children to make a difference in their life first, and then make a difference in the environment. They’re doing, that is my greatest encouragement.

Sustainability: Helping earth, not fighting it. Allowing the earth to do what it wants to do without us ruining and spoiling. Instead of creating carnage wherever we go.

Success: meeting students years later. In high school, trying to continue what we have begun here. Young children, 10-11 years old, they’re getting it, they’re embarking on a life of sustainability.

Superpower: Empowering young people, to help them understand the importance of the environment. People don’t do things unless they understand it, my job as an educator is to help them understand why we do stuff.

Kids teaching me – I love it. Boom!

Because I love what I’m doing, and because I’m enthusiastic about it, the kids love it (mostly).

Activist? I don’t think so, I’m just a passionate person who believes that passion breeds passion. Enthusiasm breeds enthusiasm. I’ve taken the time to develop a programme that works with kids, and I believe in it.

The world is filled with people who believe in things, and people who believe in things, make things happen. I what kids to know that, to believe that, that they can make things happen.

Making little things count

Tony Smith is chair of Sustaining Hawkes Bay Trust.   We talked about that role, and his career through computing and education. Tony’s family live in a wonderful home, built to celebrate a sustainable future so we talk about that too.


Talking points

See connections, join the dots.

It’s not a matter of environmental values being at odds with financial economic values – those things align.

Sustainability:  An all encompassing term.

Success: At personal level, electric car.   Hawkes Bay, traction on zero waste.   But not for profit sector is highly fragmented.

Superpower: Being aware of sustainable concepts in day-to-day decisions.  The awareness that the little things we do do add up and make a big difference.   Super-mini-man, making things count.

Activist: Probably not, I was more active.

I don’t see a conflict of activism and being a professional.   The definition of a profession is that it is self-monitoring.  So that works at an individual level.  The whole point of being a professional is that you analyse, you meta-cognate on what you are doing and why you are doing it.   If you see something that you don’t like then it is your professional ethical responsibility to do something about it.  So I don’t see activism being in conflict with professionalism at all.

It would be nice if people had more of a view of their similarities rather than differences.  I would like people to look for commonalities rather than try to create divisions.  It’s all to do with “them and us”.   My hope for humanity is that we get better at having a bigger “us”.

Small things do count.

Sustainable software engineering

Birgit Penzenstadler

If I put sustainability into the software system requirements, that means during testing I now have to test whether the system meets those sustainability requirements. What I’m doing now is finding those metrics.


Dr Birgit Penzenstadler is Professor for Software Engineering at California State University Long Beach. In her research Birgit explores the relationships between sustainability and software engineering.

We talk about Birgit’s background and motivations, her teaching and research, and the Karlskrona Manifesto,

Talking points

What are the things that we as software developers should pay attention to?

The first part (of the Karlskrona Manifesto) is about misconceptions that we have about sustainability….for example that there is a magic technical solution just around the corner that’s going to solve the sustainability problem, we’ve just got to find that one silver bullet.

…and for each of those misconceptions we explain what the reality is, and as sustainability is a very complex problem, a wicked problem – we can’t solve it with a magic bullet, it will take many things that solve different aspects of the problem and it’s unclear how we can do that.

The second part of the manifesto proposes a set of principles, for example we need to be looking at longer timescales when we develop systems, and we need to involve multiple disciplines, it can’t just be a bunch of software engineers trying develop a system, we need to get expertise from other people, for example from psychologists, ecologists…

At the end of the manifesto we give a couple of suggestions as to what people might do as the next step.

Start by discussing it, what it might mean and raising awareness.

The major push back I get is “I get my requirements from my customers, it’s not my place to say you should also look at the sustainability aspect”. So this should be part of our ethics standard, that I don’t just look at what is the maximum return on investment and is this safe for humans to use without getting hurt, but we should also look at other categories of damage.

We should always be free to point out social and environmental consequences, but the line at which we should walk away and say we’re not going to do a development…it’s hard to say where that line is.

At the moment we might be developing a lot of systems that we don’t really need.

Instead of inventing yet another system, and developing yet another software product, maybe we should be looking at simpler solutions.

Instead of products to buy, we should perhaps be better looking at sharing systems

The main intention of the Karlskrona Manifesto is to raise the discussion around sustainability, to make software engineers aware of the topic – look, it’s your responsibility to at least think about this and think what you are going to do about it.

I discuss four definitions of sustainability with my students: 1. To persist over an extended period of time.
2. To preserve a function over an extended period of time.
3. The next one (you taught me), ethics extended over space and time – this adds the notion of value.
4. (from Ehrenfeld) Life to flourish indefinitely – painting the vision of an even brighter future.

Then I tell students the other part, from Laurence Hilty – to scope your analysis well, what do you want to sustain, for whom you you want to sustain it, and what is the time horizon you want to be looking at.

For some reason, we humans tend to think that sustainability means preserving the human race on this planet, the truth is the planet would fare pretty well without us, but we still want to be around, so we strongly scope what we perceive as sustainable in that way.

I’m taking the liberty of using one of my 25 lectures on software engineering to discuss software engineering for sustainability because I think that it is important

use case

If I put sustainability into the software system requirements, that means during testing I now have to test whether the system meets those sustainability requirements. What I’m doing now is finding those metrics.

This is taking the requirements problem to the extreme.

If in requirements engineering I define what sustainability means in terms of this specific software, then I have as a starting point for the metrics that will help me determine whether that software system is sustainable…but that means I have to do work at the beginning, it means I have to do a life cycle analysis, which is not yet a standard method for software engineering.

(is it possible to write requirements to solve wicked problems?) It’s tough. I’m an optimist by nature. This sustainability research has sometimes brought me to the limits of my optimism, but I refuse to give up.

There’s a lot of challenge in doing this, but I’m going to try to find the best method that I can.

I can teach my software engineering students to start paying attention to sustainability.

I do think that every one of us, no matter what discipline we are working in, can find at least a small point of leverage.

If I have the freedom to develop a software system, what do I want the system to be about, then I can decide to make a software system that is a completely new solution that helps people to form a community and do something together instead of making small efficiency steps if the solution was not the best one in the first place.

Car efficiency versus car sharing…a case where optimising one solution further would yield far less benefit than going for a completely different solution.

(software engineering is by definition a systems view) yes, and at the same time, I think we software engineers often don’t step back enough. We’re thinking how can I break down this problem into manageable parts and solve those, when we should be taking a step back and trying to apply a systems thinking approach.

(if pushed for metrics) Environmental impact, social consequences.

The environmental impact is not just the hardware, it is what is the system going to be put to use for.

(success) Finishing up my Habilitation.

(Activist) I would say so, yes. It is not my job to teach my students about sustainability, but nevertheless I do it, and I really care about convincing them that it is worth having a discussion about.

(Not your job, but it’s not job to teach in non-racist manner, or non sexist manner either, can we get sustainability to same level? I’m teaching my students to behave professionally non-racist, sustainably…). I would make sure not be a racist in class, but I guess I wouldn’t talk about not being a racist in class during my class, I guess that’s the difference.

I implicitly adhere to good ways of behaving, because that’s what I’ve been taught culturally, and maybe we can get to that same point about sustainability.

(Motivation) When I go out into the mountains at the weekend, and I love the mountains, and I see all that beauty around me – that’s what I really want to preserve.

(Challenges) Californian in training.

(Miracle) Tough choice…I want our planet to have way left population than it currently has. Not because of a disaster, but it’s a magic wand – the population never grew to that many people. And we found better ways of using technology and not taking it to the extreme as we have over the past couple of decades. Maybe we just had a magic moment of insight a few centuries back.

(Is technology going to save us?) I don’t think technology is going to ruin or save us – it’s our choice as responsible human beings to put technology to good use such that it can help us to save ourselves and this planet.

(Advice) Listeners already care about sustainability and probably think about how they can put it into action in their personal lives – I would like to encourage all of you to continue doing that.
