the process of returning a land area to the condition it was in before humans used the land

Explanation:

Reclamation refers to the process of returning a disturbed ecosystem to its original status prior to the disturbance. Often times, the disturbance regimes that change the conditions of the ecosystem are created by humans.

Reclamation is unlike reforestation in that the latter involves the process of planting trees in order to reestablish forest lands, not necessarily return the land to its previous status.

Reclamations are often done to return lands to the original flora and fauna status before the disturbance regime.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
