Mike and his team find time to test out some of the surfboards they've built. Nearby, we visit a pier that once had a ballroom and hosted some of the biggest names in US music history, and a lighthouse commissioned by George Washington himself.

Deep in the Maine woods, sawmill owner Alan Higgins shows us how he gets along just fine by repairing and reusing what he has. When he’s not hard at work at the mill, he can be found tinkering with trucks and old sports cars in his yard.

Machines and the sawmill are not Alan’s only interests. He’s also an enthusiastic musician, with dreams of getting his own song played on the radio. Along the Maine coast, oysters are farmed where the rivers and creeks meet the sea, and we meet Judy, who’s been a waitress at her family’s restaurant for over forty years.

Over decades, Moody’s Diner has become a social hub for its long-standing customers, and any change to its décor and menu can only happen with their agreement! Maine’s Penobscot Bay, with its many islands, is famous for lobsters and sailing, and it’s here we meet Tomás Sowles, a young commercial pilot loading his plane for an early morning flight.

Tomás is sometimes greeted with incredulity by new passengers who can't believe he's so young. But the pilot has already racked up hundreds of flights between the remote island communities of Penobscot Bay, often navigating rough, unpaved forest landing strips.

Tomás’s responsibilities go far beyond the basic flying of the plane. He must weigh the risks to himself and his passengers before setting out on every route. On Isle au Haut, a small island where Tomás’s plane cannot land, Professor Marshall Chapman is waiting for some important mail to arrive by boat.

Marshall has several old Ford cars, so he’s got options if one decides not to start up for him on any given day. He’s happy to be living an old fashioned lifestyle, one that suits this isolated island. Next, we join Genevieve Kurilec McDonald at work aboard her own lobster fishing boat. She explains which lobsters she can keep, and which must be thrown back.

Today, planet Earth is in a new era, the Anthroprocene. Humankind has harnessed and exploited Earth’s resources, changing its surface, devastating populations of wild animals, cutting down trillions of trees and leaving very little of what was “wild.” The enormous loss of biodiversity is not sustainable. How can we create a future in which both people and nature can thrive?

Can planet Earth survive? Can we survive as a species? Changes in population growth could be a key factor to allowing us to prosper and live in harmony with nature once again.
