When the Senate picks up debate on
the climate change bill, we’re sure to
hear a lot about how power plants and
cars are contributing to the problem.
But a new study finds that we should
also be considering where we live. Julie
Grant reports that living in the suburbs
can create extra carbon emissions:

Most Americans live in or near big cities – but those in the suburbs have to drive a lot.

The National Research Council completed a study for Congress. It finds that building housing closer together near urban centers could reduce the amount people drive. That would save energy and cut greenhouse gas emissions.

Marlon Boarnet is a professor at the University of California, Irvine. He was on the study committee.

“The best evidence out there leads us to believe that people who live in more dense development do in fact drive less. And we feel that the evidence can conclude that that’s a causal relationship.”

Even if single-family homes were built closer together, it would mean less greenhouse gases.

Some experts in the study say the U.S. could reduce emissions by up to 11% in the next 40 years – just by building housing closer together.

Bike Shop in a Box

So many of us have an old bike collecting
dust in the garage. More often than not,
they end up in the garbage. But, as Karen
Kelly reports, one group has found a unique
way to recycle them:

(sound of banging)

“That’s a sweet ride!”

A volunteer drops a bike into a pile at the back of a huge shipping container in Ottawa, Canada.
The bikes are stacked one on top of the other.

(sound of tools)

Just outside, a mechanic is stripping the bikes down to make them as compact as possible.

“If it has a kickstand, we have to remove it. We take the pedals off and turn the handlebars.”

In a few hours, this cargo container will be jammed with hundreds of donated bicycles, bike parts, and backpacks.

The gear is collected by a group called Bicycles for Humanity.
They have 20 chapters, most of them in North America.

Each chapter raises a couple of thousand dollars to buy a shipping container.
They pack it full of donated gear, and send it off to a community in Namibia, Africa. The shipping cost – another several thousand dollars – is also raised by the group.

A volunteer group there turns the container itself into a locally-run bike shop that provides jobs and transportation.

Some of the bikes are donated to health care workers who use them to pull patients on a stretcher.

Others are piled high with stacks of food and household items that defy gravity.

Martin Sullivan points to some of the pictures on display.

“These are the bakers who are able to sell their bread. And also wood, you can stack wood. It’s just amazing what they do, how they make use of these bikes that we take for granted. We throw them out, and they can do so much with them.”

(sound of traffic)

In Namibia, cars – and even bicycles – are scarce. Sullivan says these bikes make life easier for people who are used to walking miles to get to school, work, or to find the basic necessities.

Seb Oran is the co-founder of Bicycles for Humanity in Ottawa.

This is the fourth container of bikes that she’s sent to Africa.
Each one supports a local community group.
Sometimes its a hospital, sometimes an orphanage, sometimes a women’s empowerment group.
She remembers one run by former prostitutes.

“Six of them became bicycle mechanics now. And now, they don’t have to sell their bodies to put food on their plate.”

But there are some challenges.

Michael Linke runs the Bicycle Empowerment Network.
He helps the Nambians set up the bicycle shops.

“Because this is the first time a lot of these people have had formal ongoing work, it’s often difficult to get people to understand a long-term ongoing business.”

But with some mentoring, they’ve been able to make it work.
There are now 13 successful projects, with more containers filled with bikes on the way.

The group estimates that these bikes will last another 20 or 30 years in Africa. They might be junk to us, but in Namibia, they’re a precious resource.

Coral Conservation in the Caribbean

Scientists say nearly half of the coral reefs in the US are in bad shape.
Many are dead. The situation is similar in much of the world. But not
everywhere, as Ann Dornfeld found on the Caribbean island of Bonaire:

Scientists say nearly half of the coral reefs in the US are in bad shape.
Many are dead. The situation is similar in much of the world. But not
everywhere, as Ann Dornfeld found on the Caribbean island of Bonaire:

(sound of waves on shore)

Jerry Ligon was working as the on-board naturalist on a small Caribbean
cruise ship when he first saw Bonaire.

“And I saw how clear the water was. And I’d been able to compare, during
my stint on the cruise ship, other islands in the Caribbean, and I realized
how special Bonaire was. So that was at the end of my contract, so I
decided to stay here. And I’ve been here for 15 years!”

It’s wasn’t just the clarity of Bonaire’s water that made Ligon stick around. It
was the remarkably healthy coral reefs that lay beneath the waves.

“I can even talk to divers who come to Bonaire and they say, ‘What
fantastic diving!’ and they remember, ‘This is how the way it was in Cayman
Islands 25 years ago!'”

Ligon says the Cayman Islands might have even had more impressive
reefs than Bonaire’s back in the day. But coral throughout the US and
Caribbean has been in sharp decline for decades.

So how do Bonaire’s reefs remain intact?

Ramón de León is the manager of the Bonaire National Marine Park. He
says the island has an advantage in that it has no industries to pollute the
water.

The island is mostly undeveloped, which means relatively little farm and
lawn fertilizer run-off that can create marine algae blooms. And cool
upwellings in the region help balance the rising ocean temperatures. Warm
oceans can cause coral bleaching, which often kills the coral animal.

But de León says Bonaire really owes its healthy reefs to its history of
conservation laws. They date back to an era when such policies were rare.

“Bonaire start to protect sea turtles and turtle nests in 1961, back when
everybody was promoting sea turtle soups and nailing shells in the walls.”

By the end of the 1970s, Bonaire had banned spear fishing and made it
illegal to damage coral. For years, divers have been required to pay a
sizeable fee and take an orientation course before they’re allowed to dive
on the island. That helps them avoid touching the coral, which can kill it.

De León says the island still allows too much fishing. So several years ago,
he told the island’s fishermen they needed to choose a no-take zone to let
the reefs recover.

“I refuse to decide myself. I give the fishermen some prerequisites that they
have to have to close, and they chose which area. Is not my number-one
option, but is their number-one option. So I have to respect that.”

De León says because the fishermen chose the no-take zone, something
important happened. Compliance is high.

For all of Bonaire’s success in coral conservation, there are still some
problems. De León says its reefs suffer from leaky septic tanks and boat
pollution. And there are few of the large predator fish that used to maintain
population balance on the reefs.

But the island is a haven for researchers like Mark Patterson. He designs
underwater robots at Virginia Institute of Marine Sciences.

Last year he led a NOAA expedition to use robots to map Bonaire’s reefs.
He says the island’s reefs are valuable as a baseline by which other reefs
can be judged.

“If you’re an up-and-coming marine scientist and you go to a lot of the coral
reefs on the planet now, you might think that all coral reefs have always
look like this. And they haven’t! So the fact that we’ve got some pristine
reefs left is very important, and we’ve got to work very hard to protect them
because it shows us how the ecosystem should look and used to look
around the planet before things started to go downhill.”
