Earlier this year, Sterling announced he was stepping down from his role. “I am really encouraged by the way the outdoor industry has responded to threats to our public lands,” he said. “It wasn’t always that way. Now, we’ve got a great industry that really cares and is ready to step up and use their voices.”

50%Amount of the planet we must preserve for nature if we want the vast diversity of life on Earth to survive, according to biologist E.O. Wilson. The Harvard professor explains in the book Half-Earth: Our Planet’s Fight for Life, “I propose that only by committing half of the planet’s surface to nature can we hope to save the immensity of life-forms that compose it.” half-earthproject.org

100,000 GALLONS – Average amount of water used by the average household every year in the U.S. Forty-five percent of that is flushed down the toilet. By putting a weighted bottle in a toilet tank to take up volume, a household can save up to five gallons per day.

One – Switzerland’s ranking on the 2018 Environmental Performance Index (EPI), which ranks 180 countries on 24 performance indicators across ten issue categories covering environmental health and ecosystem vitality. The United States comes in at number 27. The EPI is produced by Yale and Columbia in collaboration with the World Economic Forum. epi.envirocenter.yale.edu

1 MILLION ACRES OF PRIVATE LAND – The amount that that Kris Tompkins and her non profit Tompkins Conservation gave to the government of Chile to create a new national park.

$28.12 – The amount it cost Henry David Thoreau to build his famed cabin on friend Ralph Waldo Emerson’s land on Walden Pond in 1845. In the 10-foot-by-15-foot structure he wrote “I should be glad if all the meadows on the earth were left in a wild state, if that were the consequence of men’s beginning to redeem themselves.” No matter your thoughts on the author—some see him as an admirable sage, others as a bumbling trust-funder—Walden continues to inspire legions of conservationists. Pilgrims to the site where the simple cabin once stood have been leaving stones there to build a massive cairn in his honor since 1872. waldenwoods.org

205 billion – Metric tons of carbon that could be removed from the atmosphere (one third of what has been pumped into it since the start of the Industrial Revolution) if saplings were allowed to regrow where forests have been cleared, according to a July 2019 report in the journal Science. The report states: “This would represent a greater than 25% increase in forested area, including more than 500 billion trees and more than 200 gigatonnes of additional carbon at maturity. Such a change has the potential to cut the atmospheric carbon pool by about 25%.” sciencemag.org/content/365/6448/76

50 – Number of states that benefited in some form by the 2019 John D. Dingell Jr. Conservation, Management and Recreation Act.
