Climate change – What can I do?

By showering less often I’m cutting my water use to less than half, and turning down the flow rate reduces water use by about half again.

I’ve just watched the latest ‘Just have a think’ video from Dave Borlace. I really enjoy his videos – they are well produced, clear, uncompromising, polite, thorough … well, you get the idea. The latest one asks what we can do individually to help reduce the pace of climate change, and he describes a survey that shows most people are just waiting for someone else to do something about it.

That rings true!

Here’s the video, watch it, then scroll on down and read my personal take on, ‘What can I do?’ I believe we can have a large impact – if we all pull together.

What can I do?

I’m going to share one idea with you, something I’ve been doing for a long time now, and something I’m finding quite easy that also makes a big difference. Just remember though, this one idea is just an example. Maybe you can think of something in your own life that you could change that would also have a useful impact.

I used to shower every day, after all it takes less time, water and energy than having a bath and that has to be a good thing, right? Well, yes.

But for a number of years now, I’ve made a point of showering once every two or three days, turning down the water flow, turning down the temperature, and also minimising my use of shower gel. I still enjoy my showers, the temperature’s warm enough to be pleasant, I’m not advocating cold showers!

So how does this help?

Much more than you might think. By showering less often I’m cutting my water use to less than half, and turning down the flow rate reduces water use by about half again. So I’m using only 25% as much overall. Turning down the temperature a little combined with the reduced water use reduces the heating energy required to perhaps just 20%. I only use shower gel under my arms and around the more personal parts of my body, cutting consumption by 50% or maybe a bit more. Combined with showering less often my use of shower gel is therefore down to 20 or 25% overall.

Bear in mind that shower gel takes energy to manufacture as do the plastic bottles that it comes in, as does disposing of the empties. Add in the energy cost of producing and supplying water, and of removing and treating the waste water, and it all begins to add up.

I hope this illustrates the energy savings that can be achieved by one, small change in one person’s lifestyle. And there are other benefits too. For example, my skin microbiome is probably more healthy for the reduced frequency and coverage of shower gel. If we all did this, and thought of other ways to reduce our individual energy use, we could make a huge difference.

Don’t just leave it to others. Work out what you can do – and make a difference!

A new Christmas song

This is a family song, it’s about gathering round and spending time with the people we love most. Enjoy it!

A still from Sarah’s YouTube video

While we’re on the Christmas theme I thought I’d post another song from Sarah Reynolds. It’s quite delightful and, in a lovely way, rather old fashioned. Scroll down, have a listen, and see what you think.

This song is quite different from Sarah’s other material, I suspect it was far more spontaneous. It’s a thoughtful song. She doesn’t accompany the words with one of her usual, excellent, multi-track compositions but with a pretty melody on the piano, and there’s a gentle, relaxed rhythm throughout. The video doesn’t provide the lyrics, but Sarah’s voice is clear enough and written words are not neccesary. The graphic is suggestive of a Christmas card from past decades, well-matched to the music and the choice of piano. The whole thing breathes close family enjoying the season together, burning logs in the grate, home made mince pies, warmth indoors with cold weather outside the house.

This is a family song, it’s about gathering round and spending time with the people we love most. Enjoy it, give it a like on YouTube, Spotify, and Facebook. Go on… you know you want to!

And wherever you may be, gather with your family and friends if you can, and enjoy Christmas and New Year together.

Christmas and New Year 2021

It’s good to be out and about to see it all and just as good to get back to a warm house.

Castle Street in Cirencester

Season’s greetings to all my readers! Cirencester is showing off its tasteful street decorations once again, the days are short, the nights are long, and it’s good to be out and about to see it all and just as good to get back to a warm house afterwards.

My thoughts are especially with those who have no warm house to come back to this year, there are so many – the homeless sleeping alone in shop doorways, refugees desperately crossing the sea and hoping for asylum, and people who do have a roof over their heads but lack money for presents for the children or depend on food banks for their next meal.

Life can be wonderful, fun, exciting. It can also be tough, exhausting, and depressing. Whoever you are, whatever your circumstances, my prayer and hope is that people will be kind to you, there will be new opportunities in your life, and that there’ll be reasons to hope and overcome the difficulties.

And if your life is comfortable and you have more than enough, my prayer and hope is that you will be kind to others, search out new opportunities for them, and provide reasons for hope and ways to overcome difficulties.

None of us can solve all of the problems; but all of us can solve some of the problems.

Some ideas:

And don’t forget to enjoy Christmas with your friends and family. Grace and peace to you all.

Evolution and behaviour

A computer program that simulates coding and inheritance on the one hand, and neural function on the other, permits the emulation of simple animal-like organisms

Today I want to share two striking YouTube videos that I found recently. Maybe you’d like to watch them yourself.

Part of a DNA molecule (from Wikipedia)

Introduction – The animation shows the molecular structure of DNA, rotating so you can visualise it more easily. Watson and Crick famously published this structure in April 1953.

DNA contains the genetic information that specifies the nature of plants, animals and other life forms. Each species has it’s own form of this DNA ‘instruction book’. Amongst other things, a species’ DNA controls the basic structure of the brain just as it does for other body parts. But here’s an interesting fact: The coding and behaviour of DNA can be simulated by strings of characters stored in a computer.

Brains involve cells called neurons with connections between them, and neural networks running on a computer can behave in a similar way to a very simple brain. Building a computer program that simulates coding and inheritance on the one hand, and neural function on the other, permits the emulation of simple animal-like organisms, and there are applications out there that do just this.

First example – One such program is Minute Labs’ Evolution Simulator (check out their YouTube to see it in action).

Second example – Another program, and I want to focus mainly on this one, is from David Randall Miller. He wrote a particularly fascinating simulator, see his YouTube demo and explanation below for some quite deep insights. It’s a long video, but breaks into logical chunks for easier viewing; I suggest viewing the first section and continuing if it seems interesting.

It’s a really helpful approach for anyone wanting to better understand evolution. It assumes only fundamental levels of the topics, but will enhance your appreciation of maths and computing while also demonstrating the basics of genetics, inheritance, simple neural networks, and animal behaviour. That’s quite a lot of benefit from just one video!

Some questions to ask yourself…

  • What new understandings did you gain?
  • Did you disagree with anything?
    • If so, why?
  • What conclusions did you draw about the nature of living things?
  • Was anything surprising to you?
  • What questions do the videos cause you to ask?

Time flies!

I plan to gird up my literary loins and begin to put things right

It’s been a long, long time since my last post. I sent a hasty ‘Happy Christmas’ post on 23rd December 2020 and since then – nothing. I really have been rather busy, but also have somehow lacked the energy to make the effort. I don’t know why – perhaps I just needed a break.

In the next few days I plan to gird up my literary loins and begin to put things right. There are a lot of unanswered comments that I need to deal with first, I want to say something about a song I especially like, and I’ve been asked to write a little about my personal history. So watch this space.

Meanwhile, just for fun, here’s my friend Kevin and his daughters at the Cotswold Wildlife Park in August. (It’s well worth a visit, by the way.)

Kevin is taking a photo of a waterlily. Don’t drop your phone, Kevin! Don’t fall in, Kevin! He didn’t – but it looked risky for a moment there.
