Requirement
2. Light pollution and air pollution, and what they do to astronomy
Required
What light pollution is, and how it and air pollution affect the subject. It is also, in practice, the requirement that tells you why you are driving somewhere for requirement 4.
Notes and warnings
Note. This is the requirement that explains why requirement 4 may involve driving somewhere. From most towns the Milky Way at 4(d) simply is not visible, and light pollution is the reason.
