It’s hard to stand out amidst the clutter of Earth Day-related programming. My choice is “The 12,000 Bottle Boat” (7 p.m., National Geographic). Americans disposed of 31 million tons of plastic trash every year. A lot of that winds up in the ocean where vast islands of garbage grow in size every year.

How do you illuminate the magnitude of that waste problem? Environmentalist David de Rothschild decided to build a boat out of 12,000 soda bottles. It’s a six-person catamaran named “Plastiki” and its creator hopes it is sea-worthy enough for a 1,500 mile voyage.

• Jason Priestley stars in “Call Me Fitz” (8 p.m., DirectTV Channel 101) a comedy about a disreputable, dishonest and womanizing used car salesman. A hit in Canada, “Fitz” becomes the latest series to appear exclusively on the satellite provider.

In the past, DirectTV shared the production costs of “Friday Night Lights” in order to air that series first and then allow NBC repeat privileges. Beginning with this season, “Damages” (formerly on FX) will now air only on DirectTV.

On one level this is no different than the exclusivity enjoyed by HBO or Showtime subscribers. Except that anyone with a cable or satellite account can choose to get those premium services. To watch “Fitz” or “Damages,” you have to choose a specific provider. It’s not unlike video games that only play on certain consoles.

• The line between politician-turned-reality-star (Sarah Palin) and reality-star-turned-politician (Donald Trump) grows fuzzier by the news cycle. Tonight, Palin is profiled on “True Hollywood Story” (9 p.m., E!).

• For the record, last week’s debut of “The Paul Reiser Show” (7:30 p.m., NBC) was the lowest-rated comedy premiere in the long history of NBC. For those who still want to check out this spectacularly unfunny sitcom, tonight’s episode revolves around a botched play date.

Tonight’s other highlights

• A singer goes home on “American Idol” (7 p.m., Fox).

• A local controversy over gas drilling and poisoned water leads to two murders on “CSI” (8 p.m., CBS). A pointed, if often heavy-handed, effort to educate viewers about the dangers of a loosely regulated process known as hydrofracturing.

• Michael tries to teach Deangelo (Will Ferrell) how to run the Dundee Awards on “The Office” (8 p.m., NBC).

• A treasure hunt takes Bones and Brennan to the Everglades on “Bones” (8 p.m., Fox).

• Leslie dabbles in online dating on “Parks and Recreation” (8:30 p.m., NBC).

• A jockey’s last ride on “The Mentalist” (9 p.m., CBS).

• The cast respond when the show faces cancellation on “30 Rock” (9 p.m., NBC).

• Scott Conant hosts “24 Hour Restaurant Battle” (9 p.m., Food).

Cult choice

• A thoughtful holdout (Henry Fonda) tries to change jurors’ minds in the 1957 drama “12 Angry Men” (7 p.m., TCM). A repeat of “Private Screenings” (9 p.m.) featuring an interview with director Sidney Lumet, who died last week.
