This song is all about spraying malathion all over the city. The portion of the population that are in favour of spraying such pesticide all over the city don't really seem to care about anything since it's been known for almost 50 years (Rachel Carson's Silent Spring, which is titled Silent Spring because all of the birds had died from pesticides where she lived) that malathion kills much more than mosquitoes. I hope these people are more ignorant than not.
I'm used to waking up to the birds singing, but not today; you've successfully killed everything and you don't even care. (Oh honey, it would be so nice to have a barbeque today. Oh baby I'm so pretty bourgeoisie).
