We must, at a minimum, aim to hold on to key examples of every part of the web of life, from the Arctic to the Amazon. Although an estimated 50% of all species occur within one habitat type—tropical rainforests—the other half of all species are found elsewhere in land, freshwater, and marine environments. To conserve these, we must embrace full representation of the world's diverse ecosystems.
The National Oceanic and Atmospheric Administration (NOAA; pronounced /ˈnoʊ.ə/, like "Noah") is an American scientific agency within the United States Department of Commerce focused on the conditions of theoceans and the atmosphere. NOAA warns of dangerous weather, charts seas, guides the use and protection of ocean and coastal resources, and conducts research to improve understanding and stewardship of theenvironment.
