Meet The Island-Hopping Emergency Team That Saved Polynesia’s Birds From Extinction

One species dropped to 200 birds. Another fell to just 12. It took a conservation supergroup to bring them back.

THE GOOD NEWS:


Four of the world’s rarest bird species are once again growing in number thanks to Pacific Island conservation efforts.

If you’re an endangered flightless bird living in the South Pacific, 2018 is already shaping up to be your year. This is, in no small way, thanks to an unprecedented collaborative effort among groups ranging from environmental organizations to successful app game developers.

In what’s regarded as one of the standout conservation achievements of the last year, Alopecoenas erythropterus the Polynesian ground dove — has been rescued from extinction at the hands of invasive mammalian predators (read: rats) introduced over time by waves of human visitors.

The dove, known locally by the euphonious moniker “ tutururu,” had bottomed out at under 200 remaining, hitting the critically endangered list in 2013. And it wasn’t the only imperiled bird in Polynesia. Along with the Tuamotu sandpiper, aka Prosobonia cancellata, the tutururu now enjoys twice the stable habitat it did before the restoration team tackled the crisis.

Victory didn’t come easy. The massive operation to bring the birds back from the brink required the combined efforts of NGOs like BirdLife International and Island Conservation, corporations like Bell Labs and Tomcat, and public and private stakeholders ranging from island property owners to the French Polynesian government. The logistical and financial scope of the project even attracted the help of Rovio, the company behind the popular game Angry Birds.

While beating back the rat population, the conservation team had to focus on flora as well as fauna. In one especially troublesome instance, the inhospitable lantana plant was strangling environments once supported by island forests, which expanding coconut plantations had spent years clearing away.

Impressively, the achievement wasn’t Polynesia’s first successful wildlife rescue. 20 years ago, another rare bird, the Tahiti monarch, had dwindled to a recorded population of just 12. In addition to the ubiquitous rat menace, the group also had to keep in check cats, harriers, myna birds, and fire ants — all threats to the species. Last year, however, BirdLife was able to get the number of Tahiti monarchs up to 70 and rising.

While nature can sometimes seem cruel in its indifference to biodiversity and its outsized rewards for large-scale predators, it’s the human introduction of outside species that most reliably triggers disastrous changes in competition over habitat. But if Polynesia’s native birds have human intervention to blame for their near-extinction, they have humans to thank for their remarkable restoration too.

Sin City is doing something good for its less fortunate citizens as well as those who've broken the law this month. The city of Las Vegas, Nevada will drop any parking ticket fines for those who make a donation to a local food bank.

A parking ticket can cost up to $100 in Las Vegas but the whole thing can be forgiven by bringing in non-perishable food items of equal or greater value to the Parking Services Offices at 500 S. Main Street through December 16.

The program is designed to help the less fortunate during the holidays.

For more than 20 years. Sen. Susan Collins (R-ME) has served the citizens of Maine in the U.S. Senate. For most of that time, she has enjoyed a hard-fought reputation as a moderate Republican who methodically builds bridges and consensus in an era of political polarization. To millions of political observers, she exemplified the best of post-partisan leadership, finding a "third way" through the static of ideological tribalism.

However, all of that has changed since the election of Donald Trump in 2016. Voters in Maine, particularly those who lean left, have run out of patience with Collins and her seeming refusal to stand up to Trump. That frustration peaked with the nomination of Brett Kavanaugh to the Supreme Court.

The U.K. is trying to reach its goal of net-zero emissions by 2050, but aviation may become the biggest source of greenhouse gas emissions in the U.K. by that same year. A new study commissioned by the Committee on Climate Change (CCC) and conducted at the Imperial College London says that in order for the U.K. to reach its target, aviation can only see a 25% increase, and they've got a very specific recommendation on how to fix it: Curb frequent flyer programs.

Currently, air travel accounts for 2% of global greenhouse gas emissions, however that number is projected to increase for several reasons. There's a growing demand for air travel, yet it's harder to decarbonize aviation. Electric cars are becoming more common. Electric planes, not so much. If things keep on going the way they are, flights in the U.K. should increase by 50%.

Nearly every airline in the world has a frequent flyer program. The programs offer perks, including free flights, if customers get a certain amount of points. According to the study, 70% of all flights from the U.K. are taken by 15% of the population, with many people taking additional (and arguably unnecessary) flights to "maintain their privileged traveler status."
