Think of some environmentally unfriendly choices – taking the car instead of public transport or driving an SUV, just binning something recyclable, using lots of plastic bags, buying an enormous television, washing clothes in hot water, replacing something when you could make do with last year's model, heating rooms you don't use or leaving the heating high when you could put on another layer of clothing, flying for holidays, wasting food and water, eating a lot of beef, installing a patio heater, maybe even, as some have said lately, owning a dog. Think about your own choices, instances in which you take an action which enlarges your carbon footprint when you might have done otherwise without much trouble. Is there consolation in the thought that it makes no difference what you do?

2 Other arguments for action have nothing to do with emissions histories. See Garvey, J., ‘Responsibility’, The Ethics of Climate Change, (London: Continuum Publishing, 2008)Google Scholar.
3 The settled scientific view is that there is a 90% chance that human activities are changing the climate. This finding is endorsed by all of the national academies of science of the world's major industrialized countries (a total of 32 national academies) as well as more than 40 professional scientific societies and academies of science all over the world.

17 Singer, for his part, goes on to say that there is nothing logically inconsistent about eating meat and campaigning for animal rights, but I have a deeper, maybe wider, notion of consistency in mind.
18 Have a look at www.unstats.un.org for the numbers. The numbers in the paragraphs which follow come from this site. It is likely that things have since changed, but the point of the argument still stands.
19 I'm grateful to J. Baird Callicot for helping me see that consistency isn't the whole of morality. It's not a Vulcan view I'm pressing for with talk of consistency, just an insistence on local action in accord with global conclusions.
20 Thanks are owed to Anthony O'Hear for a very thought-provoking lecture series. I'm also grateful to the speakers and audience members for interesting talks, questions and comments.
