Environment: Earth Day 2019

Earthrise

"Wow, is that pretty!"

Astronaut William Anders took the "Earthrise" photograph (the original is shown above) during the Apollo 8 mission, December 24, 1968.
Nature photographer Galen Rowell called it "the most influential environmental photograph ever taken".  Earthrise was chosen as the symbol for the first World Earth Day in 1970.

The Endangered Species Act

The U.S. Endangered Species Act (ESA) mandates that state and federal entities protect all species threatened with extinction that fall within the borders of the mainland and its outlying territories.  The Act is administered by the National Marine Fisheries Service and the Fish and Wildlife Service.

The ESA prohibits unauthorized harvest, custody, trade, and transport of endangered plants, animals, and other at-risk organisms and allows for the application of civil and criminal penalties.  Currently there are 1,300 species listed as either endangered or threatened under the ESA.

The "Barometer of Life"

The International Union for Conservation of Nature’s Red List of Threatened Species has become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species.  The group's Red List, established in 1964, classifies species into nine categories according to their risk of extinction:
