DMPQ- . “It has been said that space exploration is bad for environment.” Critically comment the statement.

. Space launches can have a hefty carbon footprint due to the burning of solid rocket fuels. Many rockets are, however, propelled by liquid hydrogen fuel, which produces ‘clean’ water vapour exhaust, although the production of hydrogen itself can cause significant carbon emissions. Rocket engines release trace gases into the upper atmosphere that contribute to ozone depletion, as well as particles of soot.

Rocket launches are nonetheless relatively infrequent, meaning that their overall impact on our climate remains much smaller than aviation’s. But it’s not just our immediate environment: ‘space junk’ is a growing concern as disused satellites and other objects accumulate in our planet’s orbit.

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.
