About 66 million years ago, a terrible extinction event wiped out the dinosaurs. But it wasn't the only event of this kind -- extinctions of various severity have occurred throughout the Earth's history -- and are still happening all...

Paul Andersen details the evolutionary processes of speciation and extinction. Stickleback evolution in Lake Loberg is used as example of rapid speciation. Adaptive radiation is illustrated using the Hawaiian honeycreeper. A brief...

Our modern lifestyle and diet are leading to the extinction of parts of our microbiome, but we can use what we've learned from dealing with nearly-extinct macrobiota, like bald eagles, to understand the consequences and find solutions.

A massive new study has just been released showing that human activities are threatening Earth’s other life forms in some very bad ways. One million species may be at risk of extinction. Just let that sink in. Isn’t the Anthropocene...

Our new evolution simulator reveals that extinction often happens when conditions change quickly.

Humans are pretty good at destroying things. Like habitats, animal populations... you catch my drift. But, there have been a few species that humans have helped bring back from the brink of extinction. Chapters 0:00 0:05 0:11 0:17 0:23 0:29

Humans are pretty good at destroying things. Like habitats, animal populations... you catch my drift. But, there have been a few species that humans have helped bring back from the brink of extinction.

What’s the real story of the dodo? How did such a unique bird even evolve in the first place? And are we really responsible for its extinction?

Should We Let Pandas Go Extinct?

Asteroid strikes get all the coverage, but "Medea Hypothesis" author Peter Ward argues that most of Earth's mass extinctions were caused by lowly bacteria. The culprit, a poison called hydrogen sulfide, may have an interesting...

Watch these amazing rewilding videos from our friends at Planet Wild, in which they’re saving Europe’s cutest bird from extinction or resurrecting a dying forest.

When a plant or animal species that once lived stops existing entirely, we say that that species has become extinct. Why do certain species of plants and animals sometimes become extinct? According to the theory of evolution, individuals...

There have been 6 massive extinctions in our planet's history. The first, happened 440 million years ago when an Extreme temperature drops froze the oceans and killed 86% of early life on earth. Over the next 66 million years, the seas...

Learn all about mass extinctions, including the history of Earth’s five major mass extinctions, as well as the conditions of today’s human-caused sixth extinction, which is the loss of animals from the planet. Understand the history of...

Explore the concept of the sixth extinction, a period marked by significant biodiversity loss primarily due to human activities. This video delves into how climate change, industrial agriculture, pollution, and overhunting contribute...

This week on Nature League, Brit Garner explores the past and present extinctions of life on Earth.

From the wooly mammoth to the passenger pigeon, extinct species once maintained the balance of the earth’s delicate ecosystems. But human interference has resulted in dramatic loss of biodiversity. Can science restore what has been lost?...

Dr. Forrester explains how humans have had one of the most significant impacts on the environment.

Almost as rare as the plants he protects, 24-year-old Josh Styles is not your average botanist. In 2017 he founded the North West Rare Plant Initiative, a conservation project in his local region. His aim is to resurrect 44 plant species...

Brit looks back on our twelfth month on Nature League, when we explored the theme of extinction.

This week on Nature League, Brit Garner visits Makoshika State Park to see the Cretaceous-Paleogene boundary where the dinosaurs went extinct. Special thanks to Dr. Dan Lawver and Chris Torres!

This week on Nature League, Brit Garner explores extinction threats to life on Earth by breaking down a recent scientific journal article about the endangered state of the world’s insects.

This video is a lecture presentation on conservation and the importance of using our environment and its resources sustainably. The speaker discusses sustainable resources such as forests and fish stocks, and the need to manage them...

Students will explore the notion of resource conservation, and identify the differences between renewable and non-renewable resources. Some of the ways our environment may be harmed via pollution, deforestation, species extinction, and...
