What do I (we) do about my (our) carbon footprint?

A very frequent question asked by students after learning about climate change is “But what can I (we) do about it?”. Here are some ideas, all of which have benefits in addition to reducing greenhouse gases, and so are worth considering even if you reject the idea of anthropogenic global warming completely.
