For example, there is Zap Root:
ZapRoot is an unconventional bite-sized news show that covers the fast changing world of the modern Green Revolution. With sarcasm, silliness, & sanity, ZapRoot encourages you to have a better time while making a better world.
Which is part of Viro Pop:
ViroPop: Environmentalism Made Fun. Okay, let’s get this straight. ViroPop is NOT a new virus-flavored soda. And ZapRoot is not a show about bombarding plants with laser beams. What is ViroPop then? Well, you could think of it as a salad. It’s green, sure, but also cool, fresh, crisp and tasty. And full of surprises. And good for You. ViroPop is the first network on the Internet to treat the new environmental pop culture with a sense of irreverent fun. Long dreary powerpoint presentations…be gone! This is the happy Green Revolution.
And now there's MTV Switch:
Switch is MTV Networks International's Global Climate Change Campaign. We'll be looking for the best ideas and innovations that can help us reinvent how we live in ways that are cool for us and the planet. (We'll also be getting ideas from you guys, no matter how wacky...) This isn't about what we can't do, it's about what we can. It's time to Switch.
You can tell MTV Switch is cool and hip because it has its own blog. The blog covers everything from non-profit efforts, to "green" fashion, to practical tips on helping preserve the environment.
It gives me hope. Maybe sites like these will encourage a few young people to be more environmentally conscious. And maybe they'll even encourage a few green activists to be less sanctimonious and dull.
