History of marine - Education Videos

Increasing human populations have resulted in increased human impact on ecosystems. Human activities have resulted in an increased extinction rate of species which has caused a major decrease in biological diversity of plants and animals in our environment.These impacts include increased pressure from fisheries including reef degradation and overfishing as well as pressure from the tourism industry which has increased over the past few years.Shipping is a major vector for the introduction of exotic marine species, some of which can become overabundant and transform ecosystems. Collisions with ships can also be fatal for whales and can impact on the viability of whole populations, including the right whale population off the east coast of the United States.For more information.https://en.wikipedia.org/wiki/Marine_conservation
