Ocean conservation can seem an abstract enterprise, in part because we can't take a walk in the ocean and sea life remains largely unseen (most of our associations are through photographs). We don't really experience habitat the way we do on land, and the ocean is dauntingly vast. William Shatner explains away this abstraction by comparing marine habitat to domestic pets. We wouldn't let the homes of out pets be destroyed by human industry (the animals certainly wouldn't like it). The PSA ends with a strong call to action: we can speak out against the effects of industrial fishing.
