What is consseveration?

Answer 1

Conservation has two definitions that I know of in this category. One is in scientific laws like conservation of angular momentum or conservation of energy. Conservation in this sense means that that element can't be created or destroyed. Conservation of energy, for example means that energy isn't created or destroyed, but rather it changes form (like from chemical energy to heat). The other conservation is like wildlife conservation which includes programs where people try to conserve the Earth's resources, wildlife, etc.
