Environmental Ethics

Carbon caps and IVF

by Dominic Wilkinson @NeonatalEthics

Over on the Journal of Medical Ethics blog are a couple of posts that might be of interest to Practical Ethics readers.

Last week, the journal published online an article by Cristina Richie on carbon caps and IVF. She argues that the environmental costs of reproduction should lead to carbon caps on IVF, and more restrictive public access to artificial reproduction.

Iain Brasssington wrote a blog in response, ‘ARTs in a warming world‘. He wrote:

“while reproduction may be a good, it is not the only good at which persons or policies may or should aim; and there are times when two goods conflict.  Neither is it too strange to suggest that there are times when a person should abandon one good because of the greater moral gravity of some other, greater, good.  It’s possible that reproduction is one of those goods.”

I also wrote a blog in response to Richie, arguing that “Gaia doesn’t care where your baby comes from“. From an environmental point of view there seems little reason to place limits on artificial but not natural reproduction, or to restrict publicly funded IVF (as Richie suggests) to the “biologically infertile”.

Finally, Iain wrote a follow-up piece about conflicts of interest and ethical analysis. Some had criticised Richie’s arguments on potentially ad hominem grounds. Brassington argues (persuasively) that what matters are the arguments, not their origins.

Geoengineering: Lessons from Human Bioengineering

[W]e have no non-radical solutions left to deal with climate change… either we face a radical climate catastrophe or we must radically shift our economy and modes of social organisation away from the current fossil fuel economy

That was the message given by David Spratt, author of Climate Code Red, and Ian Dunlop, who formerly chaired the Australian Coal Association but has since become a climate activist, at the Breakthrough 2014, National Climate Restoration Forum, last month in Melbourne, reported by Green Left Weekly.

One source of radical solutions is the growing geoengineering industry. Recently proposed methods for the sequestering of carbon dioxide include  ants, iron sulfate  and artificial trees .

Debate continues about when and how geoengineering might ever be deployed. Amongst environmentalists, support for geoengineering methods is low. Green Left Weekly explains:

as Clive Hamilton describes in his book Earthmasters, geoengineering technologies are supported by leading climate denial organisations and by the fossil fuel industry. This is because they seem to offer a way that fossil fuel use can continue unabated. The side effects of these technologies could be brutal: for example, severe drought in Africa and Asia. Moreover, if spraying was stopped, temperatures would rise rapidly, leading to even more devastating impacts.

Will regulation help? Green Left Weekly argues that governments have been unable to regulate fossil fuel industries effectively, and that they will be unlikely to succeed more here.

It is fruitful to look at comparisons with human genetic or biological modification, or human bioengineering.

Both are complex systems affecting life processes. There has been considerable debate and reflection on human bioengineering, human bioenhancement or genetic selection. Could the results of this reflection be of use in considering the ethics of geoengineering?

Principles for the Legalization of Trade in Rhino Horn

Last Wednesday night in Kenya, on a private ranch near Nanyuki, armed gangs killed four rhinoceroses for their horns. According to a representative from the Kenyan Wildlife Service, this could be the worst rhino-poaching incident the country has seen in 25 years. 22 rhinos have been poached in Kenya this year. There are only 1,037 now left in that country, and fewer than 25,000 left in the world. The Western Black Rhino was declared extinct in 2011.

Should Vegetarians Consider Eating Insects?

In the last few years, there has been a push from various bodies—including the UN—to get Western countries to adopt eating insects as an alternative to meat. Insects have been hailed as a type of super food. They are: rich in protein; environmentally friendly to harvest; sustainable; and, they’re already eaten, and enjoyed, in many other parts of the world. There have been a number of occasions recently that I’ve been asked, as a (moral) vegetarian, for my thoughts on eating insects. “What if…?” and “Would you…?” questions are quite a common occurrence for veggies, but this one actually got me thinking.

Destroying one ecosystem and constructing another: biodiversity offsetting and particular value

Suppose that the government is proposing a new policy regarding buildings of historical significance. Rather than simply banning the destruction of ‘listed’ buildings, the new policy would allow their destruction, provided that whoever destroys the building agrees to construct, somewhere nearby, a new building of a similar size, in a similar style, exhibiting a similar range of architectural innovations, and of a similar level of beauty. Blenheim Palace could be flattened and built over with a shopping mall and carpark, provided that mall developers agreed to construct a replica of the palace somewhere nearby.

Most would be disturbed by such a policy. Part of the reason that they would be disturbed, I presume, is that it seems to manifest a failure to recognise the true value of historical buildings. Not all of the value of historical buildings consists in their possession of generic properties like ‘being beautiful’, ‘being in the baroque style’ or ‘using space to dramatic effect’. Some of their value is value that they have as particular objects, and that could thus not be realised in any other object. Part of the value of Blenheim Palace derives from it’s being the birthplace of Winston Churchill. This value could not be realised in a replica of the palace built 5 miles down the road.

Of course, no-one is proposing a policy of sort I’ve just outlined. I bring it up because I think reflecting on this kind of case may throw some light on recent discussion regarding biodiversity offsetting (see, for example, here, here  and here). Continue reading

Genetically Modifying Mosquitoes to ‘Bite the Dust’? Ethical Considerations

At some point, most people will have questioned the necessity of the existence of mosquitoes. In the UK at least, the things that might prompt us into such reflection are probably trivial; in my own case, the mild irritation of an itchy and unsightly swelling caused by a mosquito bite will normally lead me to rue the existence of these blood-sucking pests. Elsewhere though, mosquitoes lead to problems that are far from trivial; in Africa the Anopheles gambiae mosquito is the major vector of malaria, a disease that is estimated to kill more than 1 million people each year, most of whom are African children.

Political speech crime

In an article at The conversation  Professor Torcello has proposed that ‘an organised campaign funding misinformation ought to be considered criminally negligent’. I am wholly in agreement with him. I cannot think of a political party whose campaign can be characterised as anything other than an organized campaign funding misinformation and I would be delighted if we could bang them all up in chokey for it and be rid of them. Sorry, what’s that? He wasn’t talking about politicians? Well who was he talking about then? Continue reading

Living near a busy road can kill you

Early April saw some unusually smoggy days across much of Western Europe, resulting in widespread media attention to air pollution.
(See, for example, here, here and here.) On one day, air quality in some parts of London was worse than in Beijing. Further attention has been drawn to the issue by a number of recent official reports, including one from the World Health Organisation, which has declared that air pollution is now the world’s biggest single environmental threat to health.

As has been noted, media coverage can give a misleading picture of the health risks of air pollution. Coverage tends to focus on short-term peaks, such as those seen recently in Western Europe, but the health risks of air pollution are primarily related to long term exposure, and show no ’safe threshold’ effect. Elevated baseline levels of pollution are thus more of a problem than occasional peaks.

There’s another important aspect of air pollution that often goes unnoticed; small geographical differences can have a marked effect on exposure to air pollution and thus on risk of adverse health effects. For example, living near a busy road appears to substantially increase air pollution-related mortality. A study published last year in the Lancet (press summary here) investigated the effects of very local differences in air quality on mortality by pooling 22 European cohort studies. The investigators found that an increase in average annual fine particulate (PM2.5) exposure of 5 µg/m3 was associated with a 7% increase in the risk of dying from all natural causes. This is approximately the difference between living on a busy urban road and living in a traffic-free area. The finding was robust in the face of correction for various possible confounding factors.

Do we have a moral obligation protect the climate?

On 6 December, Prof. Dr. Bernward Gesang, Chair of Philosophy and Ethics of Economy at the University of Mannheim, presented an interesting talk on “Do individuals have duties to protect the climate?” exploring if individuals have moral obligation to change their behaviours to mitigate climate change from an Act Utilitarian perspective, i.e. the view that an act is permissible if and only if no other acts bring higher overall utility.

Oxford Martin School Seminar: Robert Rogers and Paul Van Lange on Social Dilemmas

In a joint event on November 15th, Prof Robert Rogers and Prof Paul van Lange presented their scientific work related to social dilemmas.

Social dilemmas are situations in which private interests conflict with collective interests. This means that people facing a social dilemma have to decide whether to prioritise either their own short-term interests or the long-term interests of a group. Many real-life situations are social dilemmas. For example, as individuals we would (economically) benefit from using public motorways without paying taxes to maintain them, but if all acted according to their self-interest, no motorways would be built and the whole society would be worse off. In the academic literature, the three types of social dilemmas that are discussed most prominently are the Prisoner’s Dilemma, the Public Goods Dilemma, and the Tragedy of the Commons. All three types have been modelled as experimental games, and research from different fields like psychology, neuroscience, and behavioural economics uses these games to tackle the question of under which conditions people are willing to cooperate with one another in social dilemmas, instead of maximising their self-interest. The ultimate goal of such research is to be able to give recommendations about how to solve social dilemmas in society.
