Human actions have had an indisputable impact on the Earth's natural environment. Human activities have contributed to deforestation, desertification, soil degradation, depletion of the ozone layer and climate change.
Space-based technologies, such as remotely sensed data, have enhanced scientific understanding of water cycles, air quality, forests and other aspects of the natural environment. These surveying and monitoring tools provide valuable information on the state of ecosystems, which offers objective support for positive environmental action, including conservation and sustainable resource management.
