Following repeated confrontational protests by the anarcho-environmentalist bicycle advocacy group Critical Mass, the San Francisco Board of Supervisors endorsed a 177-page "Sustainability Plan" for the city. The plan includes such innovative ideas as banning cars from parts of Market Street (one of the city's main thoroughfares), limits on the use of perfume and scented deodorants, subsidies for beekeeping in parks and fish harvesting in the Bay, a requirement that home sellers plant trees on their streets, and elimination of landscaping when it interferes with nesting birds. A proposal to poison all the city's stray cats because they eat birds was removed due to pressure from cat lovers.
