As the year draws to a close, there are reasons to feel cautiously optimistic about areas in which the environment scored victories in 2021. Delayed by a year as a result of COVID-19, November's COP26 - the United Nations Climate Change Conference, held in Glasgow - welcomed the world's second-largest fossil-fuel emitter, the United States, back to the negotiating table after four years of inaction on climate change. By the summit's end, the U.S. and China had made a surprise joint declaration to work together on meeting the goals of the Paris Agreement. The biggest news in forest conservation was the pledge at the UN Climate Conference in Glasgow to end deforestation by 2030; the commitment includes a pledge to provide $12 billion in funding to "help unleash the potential of forests and sustainable land use." The Biden administration spent part of its first year restoring habitat protections that had been rolled back by its predecessor. Perhaps the most prominent was the re-establishment of full protection for the Bears Ears and Grand Staircase-Escalante monuments in southern Utah, as well as the Northeast Canyons and Seamounts National Monument off New England. Populations of some of the world's most iconic species are showing some improvement as a result of protective measures. Humpback whales, whose haunting songs helped build support for the "Save the Whales" campaign that ushered in the modern environmental movement, are increasing in number in many parts of their range.
