Thomas Lovejoy, a well-known American conservation biologist who coined the term “biological diversity” in 1980, died on December 25 at the age of 80. Lovejoy, who lived in northern Virginia, spent more than 50 years working in the Amazon rainforest, founding the nonprofit Amazon Biodiversity Center and bringing worldwide attention to the threats of tropical deforestation. In 1971, he received his first grant from the National Geographic Society, becoming an Explorer at Large in 2019.

“To know Tom was to know an extraordinary scientist, professor, advisor, and unyielding champion for our planet,” said Jill Tiefenthaler, the Society's CEO, in a statement. “He was also a consummate connector, helping bring people and organizations together to preserve and protect some of our most fragile ecosystems and cornerstone species.”

In 1980, he also published the first estimate of global extinction rates, correctly projecting that by the early 21st century a huge number of species would be lost forever. Lovejoy, who held a Ph.D. in biology from Yale University, advised three administrations, the United Nations Foundation, the World Bank, and other organizations on how to protect species and advance the field of conservation biology. Since 2010, Lovejoy served as a professor in environmental science and policy at George Mason University in Virginia.

“Tom was a giant in the world of ecology and conservation,” Enric Sala, a National Geographic Explorer in Residence. “But most importantly, he was a wonderful mentor and extremely generous with his students, colleagues, and friends.”

Despite his focus on some of the world’s toughest environmental challenges, Lovejoy remained an optimist. “We all have an interest in fixing this before it gets badly out of hand, and it’s getting close to that,” Lovejoy told National Geographic in 2015, speaking about climate change. “There are things we can do together. There are energy and innovation possibilities. There are biological solutions that would benefit everyone.”
