Author Michael Pollan has often written about people’s relationship to the natural world. In a Yale Environment 360 interview, he talks about researching his latest book and what he learned about the connections between ecology and human health.

Improvements in DNA technology now make it possible for biologists to identify every living organism in and around a species. Scientists say this could have profound implications for everything from protecting amphibians from a deadly fungus to reintroducing species into the wild.

U.S. businesswoman Katherine Lucey is working with a network of women entrepreneurs in sub-Saharan Africa to sell inexpensive, household solar energy systems. In an interview with Yale Environment 360, Lucey explains how solar electricity can transform lives, particularly those of rural women and girls.

In the wake of the 2011 tsunami, the Japanese government is forgoing an opportunity to sustainably protect its coastline and is instead building towering concrete seawalls and other defenses that environmentalists say will inflict serious damage on coastal ecosystems.

Climate scientist Ralph Keeling has followed in the footsteps of his father, who pioneered the measurement of carbon dioxide in the atmosphere. In an interview with Yale Environment 360, the younger Keeling talks about the implications of crossing an alarming CO2 threshold this month.

In a Swedish fjord, European researchers are conducting an ambitious experiment aimed at better understanding how ocean acidification will affect marine life. Ultimately, these scientists hope to determine which species might win and which might lose in a more acidic ocean.

From North America to Siberia, rising temperatures and drier woodlands are leading to a longer burning season and a significant increase in forest fires. Scientists warn that this trend is expected continue in the years ahead.

Electric bicycles are already popular in Europe and in China, which has more e-bikes than cars on its roads. Now, manufacturers are marketing e-bikes in the U.S., promoting them as a \"green\" alternative to driving.
