Further experiments confirmed that human trampling was a source of constant stress and disturbance and removed a diverse interdependent community of more than 300 species including mussels, plants, and barnacles. It also weakened the community and left species vulnerable to being dislodged by winter storms. Saving the seas Marine scientists and conservationists are calling for urgent action on the ocean. Our dependence on marine life makes it essential that we reverse the degradation and work on restoring damaged habitats. It is crucial that we operate at the spatial and temporal scales that are appropriate to the problem and the habitat.
Marine reserves are one effective way to conserve marine life.
Reserves must be large enough to compensate for the effects of natural disturbances such as hurricanes. They must also be situated to take advantage of ocean currents. Since activities on land also affect the sea, land areas adjacent to marine reserves must also be protected. The call to action by the U.N. is not going unheeded. Scientists and lawyers have teamed with local communities and resource managers to address significant problems.
