Satellites and Forests
Margules Groome regularly uses up-to-date satellite imagery to assess aspects of forests. COVID-19 travel restrictions resulted in us using this technology to its fullest extent in lieu of forest site visits.
According to the United Nations Office for Outer Space Affairs, there were 7 389 individual satellites in space at the end of April 2021 and that number is increasing each year. The Union of Concerned Scientists, as of 1 May 2021, estimates that there were about 4 084 active satellites orbiting the Earth. The implication being that there are thousands of unused satellites orbiting the Earth.
