In physics, energy (from Ancient Greek ἐνέργεια (enérgeia) 'activity') is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J).
Environmental protection is the practice of protecting the natural environment by individuals, groups and governments.Its objectives are to conserve natural resources and the existing natural environment and, where it is possible, to repair damage and reverse trends.
