1) “Everything’s Trash” (shown here) debut, 10 and 10:30 p.m, Freeform. Phoebe Robinson co-created this show and plays a podcaster with no money and a cheerily messy Brooklyn life; then her “perfect” brother starts a political campaign. And yes, that’s sort of real life: Robinson, 37, co-created “2 Dope Queens” (the podcast and the HBO series); her older brother Phil has an MBA, was an executive at a non-profit and was elected to the Ohio legislature.
2) “Shark Beach with Chris Hemsworth,” 8 p.m., ABC. This is the 10th “Shark Fest,” arriving two weeks ahead of Discovery’s 35th “Shark Week.” Shows– new and rerun – continue all day on National Geographic, including “When Sharks Attack” at 8 p.m. nightly, through Friday. Unlike previous years, ESPN and ABC also join in. This hour (which debuted last year) has the “Thor” star meeting experts, including pioneering diver Valerie Taylor, 86.
3) “Green Planet,” 8 p.m., PBS. If you think sharks are impressive, watch what some fish can do. Spectacular footage sees them leap high above the water, to snatch food from branches before the monkeys can reach it. That all fits nature’s scheme to get the seeds upstream, inside the fish. Those scenes come late in a splendid hour focusing on water plants – including close-up views of the Venus flytrap’s careful selection system.
4) “Wellington Paranormal,” 9 p.m., CW. After a dryly funny (and thoroughly unrelated) bit with a suspect who won’t admit anything, we get to the main story: A meteorite has turned the neighborhood-watch people into superheroes (including Google Girl). The police disapprove, in a clever episode.
5) “SWAT,” 10 p.m., CBS. After having 90-minute openers last week, CBS settles into its summer plan for Wednesdays – new episodes of “Big Brother” and “The Challenge” at 8 and 9 p.m., with “SWAT” reruns at 10. “SWAT” is also at 8 p.m. this Friday (which will be its spot next fall), but next week that goes to “Secret Celebrity Renovation.” Tonight, it reruns its season-opener; retreating to a small Mexican town, Hondo helps a local family.
