Biosphere 2 project began in 1984, led by John Allen who called it “The Human Experiment.” The project sent eight explorers, or “biospherians,” to live in a sealed ecosystem for two years.

Natural pest control has become increasingly popular given the slew of health and effectiveness issues with conventional pesticides derived from synthetic chemicals. Since synthetic pesticides became popular after World War II, toxic chemicals have infiltrated nearly 90 percent of U.S. waterways.

It has been a tough run for electric vehicles (EVs) in recent months, with lots of bad press about everything from shorter ranges in cold weather to consumer frustration with getting stranded to the huge carbon footprint of the newfangled cars when factoring in life cycle assessments that include manufacturing.

nternational negotiators from 199 countries met in Abu Dhabi in late 2023 for the 28th Conference of the Parties to the United Nations Framework Convention on Climate Change (COP28) to try to find common ground on reducing greenhouse gas emissions and preventing cataclysmic climate change.

In recent years there has been a global movement to pressure corporations into becoming more eco-friendly. One of the most frequent measures taken by these companies is limiting the use of single-use plastics and replacing them with so-called compostable plastics.

Solar and wind power may be free and renewable, but they rely on natural processes that are beyond our control. Proponents of fossil fuels point out that if the sun doesn’t shine and the wind doesn’t blow for an extended period, the grid could suffer a so-called “energy drought” where there just isn’t enough power to meet the demand.

In 2014 the concept of solar powered photovoltaic road panels that could collect sunlight and convert it into useable energy went viral when the Idaho-based company Solar Roadways heralded it as a solution to the global energy crisis.

A snow drought occurs when there is a subnormal amount of snow accumulation. Two types of snow droughts are specified by the American Meteorological Society’s Glossary of Meteorology: dry snow drought and warm snow drought.

Scientists have found it tough to settle on a precise definition for old-growth forests. There’s no single formula to determine what is considered an “old” tree, and growth rates among tree species are varied.

The United Nations has emphasized limiting global temperature increase to 1.5°C above pre-industrial levels to mitigate the severe impacts of climate change and ensure a habitable planet.
