Isolated island group is now one of the world's largest animal sanctuaries
One of the world's most isolated island groups has just been made one of the world's largest ocean reserves.
- The small island group of Tristan da Cunha has created one of the world's largest ocean sanctuaries.
- Neither fishing nor extractive activities will be allowed in the area, which is three times the size of the United Kingdom.
- Animals protected by this zone include penguins, sharks, and many seabirds.
Tristan da Cunha, a group of volcanic islands with a mere 245 permanent residents situated between South Africa and Argentina in the middle of the Atlantic Ocean, has recently become one of the largest wildlife sanctuaries on the planet. The marine protection zone is three times the size of the United Kingdom and will protect a wide variety of animal species and prevent unsustainable fishing and extraction operations.
Tristan da where now?
Tristan da Cunha is a British Overseas Territory consisting of an archipelago in the south Atlantic. The titular island is the largest in the group at about 100 square kilometers. Those hoping to visit will have to get there by a week-long boat ride from Cape Town. The island's government gleefully notes that it takes longer to get there than it takes astronauts to get to the Moon.
The marine protection zone will cover 627,247 square kilometers (over 242,000 miles) of the ocean around the islands. It will be the "gold standard" in ocean conservation, with neither fishing nor other extractive activities allowed, often referred to as "no-take." It will be the largest no-take zone in the Atlantic, and the fourth largest anywhere in the world.
The zone includes small areas just off the inhabited islands in which sustainable fishing will be allowed, but these areas are a small fraction of the no-take area's size. Given the historical reliance of the island's economy on the sea, this consideration is quite understandable.
These protected areas join many others covered by the United Kingdoms' Blue Belt Programme of marine protection, which aims to preserve 30 percent of the world's oceans by 2030.
In a press release issued by the government of Tristan da Cunha, the chief executive of the Royal Society for the Protection of Birds, Beccy Speight, left no doubt as to the environmental significance of this protection zone:
"This is a story two decades in the making, starting with the RSPB and Government of Tristan da Cunha commencing a conservation partnership, and culminating in the creation of this globally important protected area," Speight said. "The waters that surround this remote UK Overseas Territory are some of the richest in the world. Tens of millions of seabirds soar above the waves, penguins and seals cram onto the beaches, threatened sharks breed offshore and mysterious whales feed in the deep-water canyons. From today, we can say all of this is protected."
Speight added that in 2020, the need for these protections is greater than ever. "While Tristan da Cunha may be far away in distance it is still close to our hearts and protecting it is still the UK's responsibility. Closer to home, the crisis facing nature is also huge. So huge that our wellbeing, our economic future, and our very survival depend on the choices we make now about the natural world." Speight also used the statement to issue a call to action. "We need politicians to emulate the leadership of this small community to help us build the world we all want to live in. We hope today's fantastic announcement is the first of many more that help revive our world."
For the less romantic, there are also human-centered reasons why we ought to protect the oceans. A recent study suggests that keeping fishing boats out of a mere five percent of the ocean can raise catches everywhere else by a 20 percent. As it turns out, protecting the planet we live on provides benefits.
Most important of all, what animals are protected by this?
The now protected fish that inhabit the waters are a vital food source for many kinds of animals, all of which will benefit from not having to share their food supply with humans.
The vast area is home to many species of whales, sharks, and seals. Endangered species of albatross also drop by. Many birds that live on the islands and cannot be found elsewhere, such as the Wilkins bunting and the Inaccessible rail, also stand to benefit from the new protections.
Most adorable of all, the endangered northern rockhopper penguins make a home on one of the archipelago islands. With luck, they may not be endangered much longer.

What is human dignity? Here's a primer, told through 200 years of great essays, lectures, and novels.
- Human dignity means that each of our lives have an unimpeachable value simply because we are human, and therefore we are deserving of a baseline level of respect.
- That baseline requires more than the absence of violence, discrimination, and authoritarianism. It means giving individuals the freedom to pursue their own happiness and purpose.
- We look at incredible writings from the last 200 years that illustrate the push for human dignity in regards to slavery, equality, communism, free speech and education.
The inherent worth of all human beings<p>Human dignity is the inherent worth of each individual human being. Recognizing human dignity means respecting human beings' special value—value that sets us apart from other animals; value that is intrinsic and cannot be lost.</p> <p>Liberalism—the broad political philosophy that organizes society around liberty, justice, and equality—is rooted in the idea of human dignity. Liberalism assumes each of our lives, plans, and preferences have some unimpeachable value, not because of any objective evaluation or contribution to a greater good, but simply because they belong to a human being. We are human, and therefore deserving of a baseline level of respect. </p> <p>Because so many of us take human dignity for granted—just a fact of our humanness—it's usually only when someone's dignity is ignored or violated that we feel compelled to talk about it. </p> <p>But human dignity means more than the absence of violence, discrimination, and authoritarianism. It means giving individuals the freedom to pursue their own happiness and purpose—a freedom that can be hampered by restrictive social institutions or the tyranny of the majority. The liberal ideal of the good society is not just peaceful but also pluralistic: It is a society in which we respect others' right to think and live differently than we do.</p>

The future of dignity<p>Around the world, people are still working toward the full and equal recognition of human dignity. Every year, new speeches and writings help us understand what dignity is—not only what it looks like when dignity is violated but also what it looks like when dignity is honored. In his posthumous essay, Congressman Lewis wrote, "When historians pick up their pens to write the story of the 21st century, let them say that it was your generation who laid down the heavy burdens of hate at last and that peace finally triumphed over violence, aggression and war."</p> <p>The more we talk about human dignity, the better we understand it. And the sooner we can make progress toward a shared vision of peace, freedom, and mutual respect for all. </p>
With just a few strategical tweaks, the Nazis could have won one of World War II's most decisive battles.
- The Battle of Britain is widely recognized as one of the most significant battles that occurred during World War II. It marked the first major victory of the Allied forces and shifted the tide of the war.
- Historians, however, have long debated the deciding factor in the British victory and German defeat.
- A new mathematical model took into account numerous alternative tactics that the German's could have made and found that just two tweaks stood between them and victory over Britain.
Two strategic blunders<p>Now, historians and mathematicians from York St. John University have collaborated to produce <a href="http://www-users.york.ac.uk/~nm15/bootstrapBoB%20AAMS.docx" target="_blank">a statistical model (docx download)</a> capable of calculating what the likely outcomes of the Battle of Britain would have been had the circumstances been different. </p><p>Would the German war effort have fared better had they not bombed Britain at all? What if Hitler had begun his bombing campaign earlier, even by just a few weeks? What if they had focused their targets on RAF airfields for the entire course of the battle? Using a statistical technique called weighted bootstrapping, the researchers studied these and other alternatives.</p><p>"The weighted bootstrap technique allowed us to model alternative campaigns in which the Luftwaffe prolongs or contracts the different phases of the battle and varies its targets," said co-author Dr. Jaime Wood in a <a href="https://www.york.ac.uk/news-and-events/news/2020/research/mathematicians-battle-britain-what-if-scenarios/" target="_blank">statement</a>. Based on the different strategic decisions that the German forces could have made, the researchers' model enabled them to predict the likelihood that the events of a given day of fighting would or would not occur.</p><p>"The Luftwaffe would only have been able to make the necessary bases in France available to launch an air attack on Britain in June at the earliest, so our alternative campaign brings forward the air campaign by three weeks," continued Wood. "We tested the impact of this and the other counterfactuals by varying the probabilities with which we choose individual days."</p><p>Ultimately, two strategic tweaks shifted the odds significantly towards the Germans' favor. Had the German forces started their campaign earlier in the year and had they consistently targeted RAF airfields, an Allied victory would have been extremely unlikely.</p><p>Say the odds of a British victory in the real-world Battle of Britain stood at 50-50 (there's no real way of knowing what the actual odds are, so we'll just have to select an arbitrary figure). If this were the case, changing the start date of the campaign and focusing only on airfields would have reduced British chances at victory to just 10 percent. Even if a British victory stood at 98 percent, these changes would have cut them down to just 34 percent.</p>
A tool for understanding history<p>This technique, said co-author Niall Mackay, "demonstrates just how finely-balanced the outcomes of some of the biggest moments of history were. Even when we use the actual days' events of the battle, make a small change of timing or emphasis to the arrangement of those days and things might have turned out very differently."</p><p>The researchers also claimed that their technique could be applied to other uncertain historical events. "Weighted bootstrapping can provide a natural and intuitive tool for historians to investigate unrealized possibilities, informing historical controversies and debates," said Mackay.</p><p>Using this technique, researchers can evaluate other what-ifs and gain insight into how differently influential events could have turned out if only the slightest things had changed. For now, at least, we can all be thankful that Hitler underestimated Britain's grit.</p>
