This document discusses different aspects of technology including its commercial nature, impacts on the environment, and various functions. It notes that while technology influences social and economic progress, its primarily commercial character means it is more oriented towards satisfying the desires of the prosperous rather than essential needs. However, technology can also be used to protect the environment and avoid overuse of planetary resources. As technology relies heavily on the biosphere, it is a major cause of increasing depletion and degradation of natural resources.
