President Donald Trump has reportedly ordered the U.S. Department of Agriculture to open Alaska’s 16.7 million-acre Tongass National Forest — the planet’s largest intact temperate rainforest — to logging and other corporate development projects, a move that comes as thousands of fires are ripping through the Amazon rainforest and putting the “lungs of the world” in grave danger.

The Washington Post, citing anonymous officials briefed on the president’s instructions, reported late Tuesday that Trump’s policy change would lift 20-year-old logging restrictions that “barred the construction of roads in 58.5 million acres of undeveloped national forest across the country.”

The move, according to the Post, would affect more than half of the Tongass National Forest, “opening it up to potential logging, energy, and mining projects.”

The logging restrictions have been under near-constant assault by Republicans since they were implemented, but federal courts have allowed them to stand.
