When Brother James says
I need to get a present for one of my hippy dippy friends -- any suggestions?

You can say
The best gifts are shared experiences -- they never end up in a landfill! Plan a hike and a picnic at your favorite nature spot. Other small-footprint ideas are a gift certificate to a vegetarian restaurant, a cooking or dancing class, tickets to a concert or play, or a subscription to a local CSA.

But if you do choose to buy a present, check out the Sierra Club Holiday Gift Guide for some eco-friendly options.

When Brother James says
I wish it was easy to put solar panels on our roof, but I've heard it's really expensive.

You can say
Actually, with all the new solar panel leasing programs out there, it's very easy and affordable.
