U.S. evangelical approaches to climate change
But just as America is bitterly divided on the issue of climate change, so is the evangelical movement.
At Eastern Mennonite University, in Harrisonburg, Virginia, concern about the environment is so high that the college has employed a full-time recycling officer and assistant.
Jonathan Lantz-Trisse, who travels around campus by bicycle with a trailer of recycling in tow, has been monitoring the efforts of staff and students to recycle their waste.
"The students are actually really good recyclers," he says. "Sometimes I think the challenge is getting the faculty and staff to recycle - I think the younger generations have grown up with it and it comes more naturally."
An address by the university's president, Loren Swartzendruber, gives a clue that here, too, it is the voice at the top that sets the tone for the university.
"There is a massive and mounting body of scientific evidence that global warming is a reality," he tells the gathered congregation.

Methlane lakes death traps
Lake Kivu is what is known as a "turnover lake".
Geological evidence from around the lake shows that every 1,000 years or so there have been cataclysmic events which have wiped out all animal life in a huge radius surrounding the lake.
What happens is that gradually so much methane and carbon dioxide is dissolved in the water that it begins to acquire buoyancy.
Instead of this being released gradually there is a sudden huge explosion, where the lake effectively turns over.
The gas laden water from the bottom of the lake surges to the surface, releasing billions of cubic metres of gas; this settle like a huge toxic blanket over the surrounding area.
It is heavier than air so all the oxygen is forced out and all life is suffocated.
This is what happened at Lake Nyos in Cameroon in 1986, when 1,700 people were killed.
Lake Kivu is hundreds of times bigger than Lake Nyos and it is estimated that more than two million people would die.
