The 1969 Santa Barbara oil spill galvanized the modern environmental movement

Understanding the causes and environmental impacts of crude oil spills and leaks

Although some oil regularly leaks from the bottom of the oceans through the gradual erosion of sedimentary rock, major spills result from accidental ruptures of pipelines or damage to transportation vessels or rigs. Oil can break down the water-repelling ability of feathers, remove the insulation of fur, and poison food chains if ingested.

The environmental crises of the late 1960s led to the founding of the EPA

Disasters such as the Cuyahoga River fire and the Santa Barbara oil spill prompted Congress and President Nixon to establish the Environmental Protection Agency in December 1970, with the goal of unifying federal efforts to control pollution.

How microbes limited the damage and helped clean up the Deepwater Horizon oil spill

A bloom estimated to contain about 100 sextillion microbial cells broke down much of the 4.1 million barrels of spilled crude oil into nontoxic compounds in what was one of the most significant bioremediations of a human-made disaster. The microbes involved acted similarly to the first patented genetically modified organism in US history: an oil-eating bacterium engineered in 1971.

The number of annual oil spills has dropped dramatically since the 1970s

Oil spills from oil tankers—which can have a sharp, short-term impact on oil prices—have become increasingly rare over the decades in part because of stricter regulations.

Santa Barbara divers helped innovate deepwater diving technology

Divers in the Santa Barbara channel innovated a more efficient type of diving helmet in the 1960s that used helium to allow for longer, deeper excursions for oil surveying, abalone collecting, and more. These innovators have since set the standard worldwide for military and industrial diving.

Large oil companies knew about the impact of carbon emissions since the ’70s

Watch a 1986 television special about the discovery of the ozone hole

The groundbreaking discovery of the Antarctic ozone hole in the mid-1980s marked a critical turning point, galvanizing international action to address the ozone-depleting properties of chlorofluorocarbons, which had been identified about a decade earlier. This environmental crisis was brought vividly to public attention through media pieces like this one.

How the California wildfires are impacting wildlife

The deadly 2025 Eaton and Palisades Fires in California have devastated neighborhoods, forested canyons and chaparral—a type of shrubland. In addition to taking dozens of human lives and displacing thousands, the fires destroyed countless habitats and displaced many species. See the unfortunate effects of the flames on wildlife populations, including birds, snakes, wildcats, and fish.

After swallowing 23 pieces of plastic, seabirds experience a 90% death rate

Researchers found that this threshold is also met when marine mammals ingest 29 pieces and when sea turtles consume approximately 405 pieces. Almost half of the sea turtles, a third of the seabirds, and one in ten of the marine mammals studied had eaten plastic.

Santa Barbara's Channel Islands revealed the oldest skeletal remains in North America

The harsh realities of the Great Pacific Garbage Patch

Misleading images and narratives have caused the public to believe that the Great Pacific Garbage Patch is simply a large clump of floating trash in the ocean. Instead, a more apt description would paint it as a dispersed "soup of microplastics" that severely impacts marine life and the fishing industry. Read for a greater understanding of how the GPGP came to be, and the measures that need to be taken for a cleanup.

The Standing Rock Sioux led a nationwide protest movement against an oil pipeline crossing their land

Beginning in 2016, thousands gathered at the Standing Rock Indian Reservation to block a crude oil pipeline that would run beneath Lake Oahe, the tribe's source of drinking water, and through a Sioux burial ground. The Obama administration halted construction, but Trump revived it weeks after taking office.

The 1967 war was the first use of oil as a geopolitical weapon

Following the June 1967 Arab–Israeli war, Saudi Arabia, Kuwait, Iraq, Libya, and Algeria embargoed oil shipments to the US, UK, and West Germany. While the move did not have a large impact, it reshaped global oil flows, and foreshadowed OAPEC's later actions.

A 1987 garbage barge that no state would accept accidentally sparked the US recycling movement

In the 1980s, an Alabama businessman loaded 3,168 tons of mafia-controlled New York trash onto a barge. It was rejected by six states and three countries, sparking a media frenzy. This event helped convince Americans that they were running out of landfill space, giving rise to curbside recycling.

The tragedy led to more widespread nationwide protests, shutting down more than 200 colleges and universities. The event led to a Pulitzer Prize-winning photo of a slain and grieving student.

In 1820, a sperm whale sank a ship and inspired 'Moby-Dick'

The Essex's crew hoped to capture sperm oil, a lucrative material found in the heads of sperm whales. However, a whale charged and crashed into the ship. Survivors of the attack drifted at sea for months, and many experienced starvation, dehydration, and cannibalism. The ordeal inspired author Herman Melville.

The day the dinosaurs died

Roughly 66 million years ago, a giant meteor struck Earth off the coast of the Yucatán Peninsula. Some dinosaurs died in the immediate impact, which sent a 200-foot tsunami all the way up to what is now North Dakota. Many others perished in the resulting change in climate, with debris ejected into the global atmosphere. This 12-minute video provides an overview of what scientists have uncovered about the fateful day.

The history of soap and how it forms bathtub scum and white spots in old oil paintings

Soap has been produced since at least 2,200 BCE via a chemical reaction between fats or oils and a base. This creates salts that act as molecular bridges, helping water lift dirt and grease from surfaces. The same chemistry produces scum when metals in hard water bind to soap molecules, as well as white spots in paintings when metal ions in pigments react with fatty acids in the oil binder.
