Respect For Life

Once we used to think that microbes were just 'germs', harmful and to be wiped out wherever possible. Now we are beginning to realise just how important they are.

In our guts we have an immense and complex microbial ecosystem, which affects our health in many ways. Whenever we take oral antibiotics that is really badly messed up. It would be a lot better if we kept antibiotics as a last resort and instead focussed on helping our gut microflora develop in ways which are healthy for them and for us. Respecting the life which is inside us and working with it rather than against it.

Researchers are also just beginning to home in onto a similar complexity of microbial life on our skins and in our mouths. It would be good if some serious studies were done on the consequences of wiping out parts of these communities with antiseptic soaps and mouthwashes - they may be doing more harm than good. Our microbiome is a lot more complex than we had previously realised; it should be treated with respect.

It is fairly well known now that insecticides are problematic. They kill insect predators as well as the main insect 'pests' - and the latter are much quicker to develop resistance. They also tend to accumulate up the food chain. Adjusting conditions to favour a more balanced and stable ecosystem is, in the long run, far more effective.

When it comes to effective use of the earth's land surface to grow food for the human population, studies have shown that some areas are best suited to growing plants for food and other are best suited to rearing animals. To feed our growing population fairly and effectively requires both plant foodstuffs and meat.

The proportion of the ideal diet which is meat should be significantly lower than the current average in the developed world, and significantly higher than parts of the developing world. Intensive rearing and general 'factory farming' are not efficient users of resources, so more sustainable patterns are required, for both plants and animals. Again we should be aiming to work with complex ecosystems rather than against them, recognising that monocultures and mass poisoning are both ineffective and inefficient.

One of the features of a successful ecosystem is that life and death are both a part of the web. I don't want to go all Disney 'circle of life' - reality is far more complex with its webs and time dependencies - but respecting life includes respecting the place of death. Every living thing dies (more or less), it is a part of life. Killing unnecessarily is disrespectful of life, but so is pretending death won't happen.

If humanity is to survive on this planet in the longer term we need to find ways to integrate ourselves into the wider ecosystem. In part that means stabilising our population; in part it means using sustainable food production methods, utilising both plants and animals; but mostly it means respecting life in all its diversity and complexity and working with it rather than against it. We are a part of something far larger than ourselves.

To apply this to the questions raised in my 'Cecil' post: as a generalisation a diverse ecosystem is healthier and more resilient than a narrow one. New species form and old ones die out, but we should do what we can to maintain a balance, and should certainly avoid putting unnecessary pressure on species and their environments.

As a slight aside, respect for the diversity of life in ecosystems across the world should be accompanied by respect for diversity within humanity, in my view. Both are essential for wholeness of life in the present, and stability of life into the future.

A final 'Cecil' question was about 'speciesism' - how far should we treat homo sapiens' life as being uniquely valuable?

From a Chrstian point of view, we believe that men and women are all made in God's image, and should be respected as such. But we also believe that we are called by God to be responsible stewards looking after this world, not just exploiting it for our own ends. All life came from God and should be treated with care and respect.

There is a bit of a question mark over what particular aspect of people is 'in God's image'. It is unlikely to be physical - as God is spirit - so it is more likely something to do with creativity and free will and 'sentience' - the ability to feel and experience subjectively. Some animals show signs of doing these things too, to a greater or lesser extent.

Does that mean that some are closer to God's image than others, with mankind at the peak? Could that be a basis for valuing a dolphin's life, say, over a tuna's?

I'm not really sure how well that works, but I do believe that a respect for life in all its aspects is a fundamental of living in the best way we can.

Cecil The Lion: Drawing A Line?

In the early thirties Ernest Hemingway went hunting in East Africa and it helped cement his reputation as a "man's man". A few weeks ago Minnesota dentist Walter Palmer went hunting in Zimbabwe and was widely seen as an inadequate person with more money than humanity. Times change.

Shortly after the fuss started about Cecil the lion I noticed vegans making comments on the hypocrisy of people complaining about the killing of Cecil yet still eating meat. We should respect all living things, we were told, not just the charismatic ones.

It seems a fair point, until you start to think about the breadth of the term 'living things' - from smallpox to blue whales, and from caterpillars to human beings. When we take antibiotics we are killing millions of tiny creatures; even an antiseptic wipe wreaks mass slaughter. Insecticides on crops kill insects - living creatures - and pest controllers kill rats to protect the health of families. Actually plants are living things as well, but that's an old argument.

Where do you draw the line?

As I understand it vegans don't eat fish or crustaceans, neither do they eat eggs or milk, nor birds or mammals. Insects and insect products (such as honey) are apparently disputed. As far as I know veganism does not include avoidance of crops on which pesticides have been used. It's drawing a line quite low, but nowhere near low enough to include all living things, not even all animals.

At the other end of the scale there are those who are perfectly happy with killing animals (or causing animals to be killed) but consider killing humans as murder and morally wrong. Again a line is drawn.

As an aside I note that Walter Palmer, as a citizen of the USA, is from the nation with the highest murder rate in the developed world - triple that of neighbouring Canada and nearly five times that of the United Kingdom. Maybe a carelessness about the lives of animals bleeds over into carelessness over the lives of people.

Then there are many who would draw lines somewhere in between. Maybe based on charisma or cuteness, maybe on perceived intelligence or assumed sentience and awareness; maybe based on conservation or ecological criteria. So eating tuna might be considered ethical so long as no dolphins are harmed in catching them, for example. Or beef might be fine as people breed vast numbers of cows, whilst lions and many whales are rare and declining in number.

I wonder about this sort of line drawing, in part because I keep reading about Jesus refusing to do so himself. Jesus, it seems to me, had a habit of approaching such questions sideways on, looking at issues in terms of underlying attitudes rather than black and white dividing lines.

Is there another of looking at the killing of animals? Can a respect for life inform our attitude to all living things, not just higher animals? And how important is 'species-ism' - the idea that killing other homo sapiens is far more abhorrent than killing other species?

This post is long enough, I reckon, so I'll end here and look at these issues in another post.
