Many organisms like coral and even people create their own minerals to perform basic life functions. Geologists can study these biominerals to learn more about Earth. (Donald E. Hurlbert, Smithsonian)
Evolving Climate: The Smithsonian is so much more than its world-renowned exhibits and artifacts. It is an organization dedicated to understanding how the past informs the present and future. Once a week, we will show you how the National Museum of Natural History’s seven scientific research departments take lessons from past climate change and apply them to the 21st century and beyond.
Minerals are known for their geologic origins, but they aren’t exclusively made by Earth. For over 3.5 billion years, living organisms have also been creating their own hard parts: biominerals.

CARY – SAS will work with the Amazon Conservation and the Healthy Reefs for Healthy People (HR4HP) Initiative led by the Smithsonian National Museum of Natural History, with three objectives: stopping rainforest deforestation, improving reef health, and reducing the carbon footprint of the Cary-based company.
SAS announced the news earlier today in a press statement.
“We feel a responsibility to use our technology and our resources to find answers to the world’s most pressing needs.” said Susan Ellis, Brand Director and Head of Social Innovation Programs at SAS, in the statement. “But it is our employees’ passion and commitment to social innovation that makes it a powerful force for change.”
Humans have been reshaping ecology across most of the Earth for at least 12,000 years, but ancient civilizations did not misuse the land like today s inhabitants, a new study reveals.
A team of international scientists determined for most of history, humans have occupied the same amount of land across the globe and by 10000 BC, nearly three-quarters of the surface had been transformed.
The new analysis also contradicts the notion that most of Earth s land was uninhabited as recently as 1500BC.
However, the main cause of the current biodiversity crisis is not due to the destruction of uninhabited wildlands, but rather the appropriation, colonization and misuse of resources.
PNAS) shows that land use by human societies has reshaped ecology across most of Earth s land for at least 12,000 years. The research team, from over 10 institutions around the world, revealed that the main cause of the current biodiversity crisis is not human destruction of uninhabited wildlands, but rather the appropriation, colonization, and intensified use of lands previously managed sustainably.
The new data overturn earlier reconstructions of global land use history, some of which indicated that most of Earth s land was uninhabited even as recently as 1500 CE. Further, this new
PNAS study supports the argument that an essential way to end Earth s current biodiversity crisis is to empower the environmental stewardship of Indigenous peoples and local communities across the planet.
