Environment: Week's Watch

Like other suburbanites, most citizens of Cleveland's Shaker Heights just love dogs—their own, that is. Other people's merely make messes. Those who own no dogs find their scat a common danger to the unwary footstep and an offense to the wandering eye. After receiving 82 complaints in one month, Shaker Heights' city council finally approved an ordinance which declares that "no person being the owner or in charge or control of any dog shall allow or permit such dog to commit a nuisance" on any public or private property without the property owner's permission. Offenders would be subject to fines of up to $500, six months in jail, or both. Shaker Heights now has the problem of enforcement; no arrests have yet been made, but some dog-owners are now following their pets around with scoop and broom. -

Every morning and evening, five days a week, commuters to San Francisco take to their cars and turn the roads leading to the city's two big bridges into fume filled alleys of torpor and noise. Last week, discarding the usual answer of building more bridges, the state's division of Bay Toll Crossings acted to attract fewer cars. As an experiment, two lanes on the Bay Bridge from Oakland were reserved for cars carrying three or more riders. Such car pools pass through its toll booths free during morning rush hours; otherwise the daily 500 fare is collected. The experiment, which will last indefinitely and cost the state $160,000 a year, should save commuters in car pools $20 a month and keep about 1,500 cars out of town each day.
