I’m assuming “endangered specials” is a typo and should be “endangered species.” This is more legislation that will crush the environment and our natural resources and habitats. Pendley basically wants to open and expose ALL available land in the United States to fossil fuel extraction, regardless of its impact on the land and its inhabitants.
In addition to the environmental impact, the Antiquities Act has been instrumental in protecting archaeological sites and historical landmarks, such as Native American ruins and petroglyphs. Repeal would leave these sites vulnerable to looting, vandalism, and destruction by development or natural decay. Not to mention the inevitable job losses when resources are depleted.
