Since the publication of the General Wild Life Law in México, the management of non-hunting wild life resources was transformed, and the sustainable management and exploitation of these resources became an obligation. The exploitation was typified as extractive and non-extractive, with the first referring to that which implies the use of specimens, parts or byproducts of a flora or fauna species through gathering, capturing or hunting; and the second, to activities that do not imply the removal or specimens, their parts or byproducts. Some examples of the latter are: swimming with sharks or whales, or sighting of whales and birds.
