In the 1960s plastic bags came along promising convenience and cost-effectiveness. Nevertheless, overuse has caused it to suffer some severe environmental repercussions.

Annually, more than 5 trillion plastic bags are made and most of those end up in oceans and landfills where they take centuries to decompose. The Environmental Protection Agency says plastic bags contribute significantly to the pollution of marine ecosystems, harming wildlife and entering the food chain.

In the 1930s, chlorofluorocarbons (CFCs) were taken up widely as safe, nonflammable refrigerants and propellants. Their use expanded rapidly, making them common in household and industrial applications.

However, scientists later found out that CFCs were depleting the Earth’s ozone layer, and therefore, increased UV radiation made it to the surface. The discovery prompted the global adoption of the Montreal Protocol in 1987, phasing out CFCs. According to NASA, the ozone layer is slowly recovering. But this episode serves as a stark reminder of unintended environmental consequences.

Thalidomide

In the late 1950s, thalidomide was released as a sedative for pregnant women and as a treatment for morning sickness. While initially praised for its safety, it soon became linked to severe birth defects in thousands of children worldwide.

The tragedy led to stricter drug regulations and a more cautious approach to pharmaceutical approval. “Thalidomide changed the landscape of drug safety assessment,” says Dr. Frances Kelsey, who famously prevented its approval by the U.S. FDA. Thalidomide is a reminder today of the critical nature of testing and oversight that must be in place in medicine.

They were designed to be cheap and convenient as single use plastics: straws, bottles, packaging. But their use has been so widespread and has led to grave environmental consequences.

According to the Ocean Conservancy, over 8 million metric tons of plastic waste enter the oceans each year, threatening marine life and ecosystems. There is a growing call worldwide to cut down on single use plastic.

Pesticides and Environmental Harm

Modern agriculture wouldn’t be modern without pesticides: they’ve boosted crop yields that have helped to reduce food scarcity. But because they’ve been overused and have persisted in the environment alike, their use has caused long-term ecological damage.

200,000 people a year die from pesticide poisoning, according to the United Nations Food and Agriculture Organization. But pesticides have also been blamed for the decline of pollinators, including bees.

OxyContin and the Opioid Epidemic

The prescription painkiller OxyContin was marketed as a breakthrough in pain management starting in the mid-1990s. But it was too widely used and had too much of an addictive quality, so it led to the opioid epidemic in the United States.

Since 1999, an estimated 500,000 people have died of opiate overdoses, according to the Centers for Disease Control and Prevention. Legal actions and policy changes aim to address this public health crisis.

Microbeads’ Environmental Impact

Asbestos was once hailed as a revolutionary material due to its heat-resistant properties and affordability. Widely used in construction, insulation, and fireproofing, it seemed like a miracle solution.

By the mid-20th century, however, evidence emerged linking asbestos exposure to serious health issues like lung cancer and mesothelioma. According to the World Health Organization, approximately 125 million people are still exposed to asbestos in the workplace, illustrating the long-lasting impact of this hazardous material.

Dichlorodiphenyltrichloroethane, or DDT, was introduced during World War II to combat insect-borne diseases like malaria and typhus. It earned acclaim for saving countless lives but soon revealed a dark side.

Rachel Carson’s seminal book, Silent Spring, highlighted DDT’s detrimental effects on wildlife and ecosystems. Scientific studies by Scientific American have since confirmed its role in the decline of bird populations and its persistence in the environment. In 1972, the U.S. banned DDT due to these environmental and health concerns.

Leaded gasoline was introduced in the 1920s to improve engine performance and reduce knocking. It quickly became the norm worldwide, but its harmful effects were not immediately apparent.

Over time, lead exposure from gasoline emissions was linked to serious public health issues, including cognitive impairments in children and increased crime rates. A study by the National Bureau of Economic Research found that the phase-out of leaded gasoline in the U.S. was associated with a significant decrease in violent crime.
