What is good for 'the environment'?

Recently I've been pondering claims that various practises are good for 'the environment'.  I've come to the conclusion that such claims are often dicey - not because of 'greenwashing' (although that's real), but because there isn't, exactly, an 'environment'.  Instead, there's a whole bunch of systems, which often need quite different things to support them.  Sometimes the things different environmental systems would benefit from are even directly opposed to each other.

The place I see this most starkly is plastic packaging.

On plastic straws and lollipop sticks

I'm going for a walk twice a week at the moment, mostly around Oakley Creek and the neighbouring streets and shared path.  As I walk, I pick up rubbish: I ignore things that will biodegrade reasonably quickly, but gather most of the plastic, metal and glass that I see.

I have noticed that I seem to pick up similar numbers of plastic straws and plastic lollipop sticks.  These seem similar to me in terms of environmental harm: if a straw can get stuck in a turtle's nostril, surely so can a lollipop stick?  So why do I see frequent calls for a straw ban (and bans already enacted in many places overseas), yet never a call for a plastic lollipop stick ban?

Vegan ice cream and frozen desserts

I spent a lot of last winter devising vegan ice cream recipes: mostly to put together a recipe book for our niece for Christmas, but also for our own use.  Why?  Although we're not vegan, we've cut back a fair bit on dairy consumption in recent years for the sake of our neighbours who are most at risk from climate change.  Dairy products are nothing like as bad for the climate as meat, but they're a lot worse than eggs or plant-based protein so we try to restrict them a bit.  Also, I'm becoming increasingly uncomfortable about all I'm hearing about the treatment of bobby calves in the dairy industry, and do wonder from time to time about giving up dairy entirely.

The internet is full of vegan ice cream recipes - however, I wasn't that satisfied with them.  Most are based on either bananas, coconut milk or cashew nuts.  Both bananas and coconut milk have quite strong flavours - that's fine if those are the flavours you're after, but they do limit your options.  And cashew nuts, as well as being quite expensive, are hard to work with.  If you want a smooth product, you have to soak the nuts, blend them to a paste, then force that paste through a cloth.  I've never actually tried it so I could be wrong, but that sounds like very hard work!

So I wondered, could you make ice cream using relatively-flavour-neutral soy milk?  It turns out you can, although I haven't found anyone on the internet publishing such recipes.  The trick is to add neutrally flavoured oils to bump up the fat content, then add soy lecithin (a natural emulsifier) to get the milk and oil to mix.  Turns out it works a charm!

One month trial of high protein, low carbohydrate diet for CFS

In recent years there has been some research* indicating that the cells of people with CFS may not get energy from glucose as well as regular people do, but may still be able to derive energy normally from protein.  They didn't look at processing of fat (the other main thing we get energy from), although at least one other study indicates there may be issues there, too.

* this research is explained in more lay terms here and here.

With this in mind, I decided to do a six-week trial of a very high protein, very low carbohydrate diet.  If my body was functioning like the cells in the trial, this should give me more access to energy at a cellular level, which ought to translate to more perceived energy :-)  The idea was to be as strict as I could manage with this diet then, if it proved helpful, to gradually figure out how strict was necessary.

What can we do about microplastic in the ocean?

You have probably heard about the problem of microplastic in the ocean: tiny pieces of plastic, too small to see, that sea creatures mistake for plankton.  They eat it, filling their stomachs with inert bulk, starve and die.  There is little evidence that this microplastic concentrates up the food chain (and the only time you're likely to personally eat it is whilst eating shellfish), but killing off a swathe of the bottom of the food chain still is surely unhealthy for the ecosystem as a whole.  It is also pretty disrespectful to the God who made the oceans.

What can we do about this?

Later I give my reasons in some detail, but, in brief, I have come to think that the most effective things we in the West can do are:

1. Drive less and always drive with well-inflated tyres and well-balanced wheels;
2. Avoid wearing petroleum-based synthetic textiles such as polyester and poly cotton blends (and wash those we do wear less often).

We can also work towards change in areas we don't affect directly:

1. Support charities that improve rubbish collection in the majority world and lobby aid donors such as NZAID to do the same;
2. Lobby councils and the Ministry of Transport to install road surfaces that are less eroding of tyres;
3. Lobby local councils to collect storm water and remove as much of the microplastic found there as possible.

Any one of these would have far more impact than bans on plastic microbeads, which are a negligible source of microplastics.

On the other, supporting bans on plastic bags may well be useful: I suspect that such light, easily-blown-away plastic items are likely to make up a significant part of the plastic not landfilled or recycled in NZ.  Participating in beach cleanups will also help prevent some of the items that didn't make it to a bin from entering the ocean.
