I’m in a room stacked with rows of 50 gallon fish tanks, surrounded by gurgling water pumps. But this isn’t a fish store. I’m with conservation biologist Jessie Bushell in a building way behind the scenes of the San Francisco Zoo. She’s giving me the lowdown on the tadpoles’ menus.

“These guys eat primarily algae,” says Bushell, “so we give them a variety of algae. We give them the gel that we make here, so we plate that out, and then we also have a different type of algae gel that we plate for their evening meal.”

One of the Bay Area’s main attractions is its proximity to nature. Only 45 minutes separate Bay Area residents from arriving at the ocean, the mountains, or a hiking trail. But not everybody experiences the Bay Area’s natural beauty. A 2012 study by the Outdoor Foundation found that only 11% of outdoor recreation participants are black. And National Parks Service estimates that black Americans comprise only  7% of its annual visitors.

On the next Your Call, we’ll speak with Jon Young, author of What the Robin Knows: How Birds Reveal the Secrets of the Natural World.  Understanding bird language, says Young, leads us toward a deeper connection to animals…and to ourselves. What can we learn from paying closer attention to what other species are up to?  Join us at 10am PST or post a comment here.  How does bird-watching connect us to our surroundings?  And why does it matter?  It’s Your Call with Rose Aguilar, and you.
