Is it just us, or does An Inconvenient Truth make saving the planet look, well, inconvenient? Don’t throw in the radioactive towel just yet. Start slowly — by adding a little easy green to your life.

Earth: The Central Park Conservancy maintains 843 beautiful acres of urban landscape — and they can’t do it alone. On August 25, from 10 a.m. to 1 p.m., help them weed the Park. You’ll get a free guided tour in return. R.S.V.P. by August 23 to matoria@centralparknyc.org.

Fire: Forget B&W movies. Go green at Solar One’s Solar-Powered Film Series, a free, two-week indie fest being held in an outdoor ecotheater (Stuyvesant Cove Park, Avenue C, near 23rd Street).

Water: For the next two Sundays, the Hudson River Park’s Clean Sanctuary Campaign needs help collecting debris at Pier 45. (No one promised glamour, just do-gooding.) Afterward, head to the Downtown Boathouse for a free paddleboat ride.

Wind: On August 29, in honor of the first anniversary of Katrina, Share Our Strength’s Restaurants for Relief program will send dinner proceeds to Gulf Coast rebuilding efforts.

Fifth Element: Befriend NYC’s shelter dogs by walking them around the neighborhood. They’ll get fresh air, exercise, and an “Adopt Me” vest that makes them irresistible to prospective pet parents.

A feel-good valentine for the planet (and your heart)? That’s never inconvenient.
