Letters to the Editor, Sept. 7: Keep the bay clean

San Francisco Chronicle

Regarding “A colossal comeback” (Page One, Sept. 5): Thank you for the informative article about the reasons for the abundance of humpback whales this year. I do think it’s worth mentioning that the Bay Area’s efforts to clean up the San Francisco Bay and the surrounding watershed have provided the healthy environment for these beautiful marine mammals... Save the Bay and San Francisco Baykeeper, as well as many other individuals have fought to clean up this beautiful body of water for years.

The Clean Water Act in 1972 created new standards for our water.

Let’s give these historical players and actions credit for helping bring back the fish and everything that eats them. It certainly motivates me to continue fighting for a clean watershed and environment if our rewards are all these beautiful creatures on display.
