Destruction of natural barriers


Destruction of natural barriers between ecosystems, such as by the creation of sea-level canals between previously separated oceans, may result in ecological disasters. Such destruction may result from atomic-blasting of channels as is proposed for the Panama link, or it may be progressive as a result of continued dredging operations as in the case of the Suez Canal which has been gradually deepened over the years, permitting more species to travel from the Red Sea to the Mediterranean.
