Causes of Ocean Habitat Loss
There are many reasons of ocean habitat loss and many things that cause it.
Humans and Mother Nature share blame in the devastation of ocean habitats, but not equally.
Hurricanes and typhoons, storm surges, tsunamis and the like can cause huge, though usually temporary, disruptions in the life cycles of Animals and plant. Though Human activities, are significantly more persistent and impactful.
Wetlands are searched and filled in to accommodate industrial, urban and agricultural development. Cities, factories, and farms create waste, pollution, and chemical effluent and runoff that can wreak chaos on reefs, sea grasses, birds, and fish.
Tourism brings millions of boaters, snorkelers, and scuba divers into direct contact with fragile wetland and reef ecosystems. Container ships and tankers can damage habitat with their hulls and anchors. Leaks of crude oil and other substances kill thousands of birds and fish and leave a toxic environment that can persist for years
Destructive fishing techniques like bottom trawling, dynamiting, and poisoning destroy habitats near shore as well as in the deep sea.
The ocean has always been seen as an unlimited source of food for humans, we have been trying to take advantage of this by trying new methods of fishing and more effective ways, and because of this we have begun overfishing. Overfishing is causing the collapse of earths most important marine ecosystems, and threatens the main source of protein for over 1 billion people.
Overfishing is simply catching fish at a rate higher than the fish species can replace themselves. The reason of overfishing is massive improvements in technology have enabled fish to be located and caught in large numbers and from deeper, more inaccessible waters.

The biodiversity of reefs supports the aquarium and aquaculture industries, biomedical industry and other commercial industries. The management of coral reef fishers falls across many different groups, including NOAA through the regional fishery management state and councils, territory commonwealth and local agencies. Because over-fishing has become a huge problem in the Great Barrier Reefs, the Australian government had to make plans in order to help future projections. Overfishing of important herbivores has only been increasing over many decades. Direct overexploitation of different fishes and invertebrates by recreational, subsistence, and the commercial fisheries has resulted in the rapid decline in populations. The NOAA has proof that overfishing effects fish size, abundance, species composition and genotypic diversity. Also, overexploitation of marine organisms contributes to the degradation of coral reef ecosystems as a whole.
Sea Changes
Ongoing efforts to safeguard ocean habitats include the creation of gigantic marine sanctuaries where development is curtailed and fishing is prohibited. Laws banning the dumping of sewage and chemicals into the ocean and policies that foster better stewardship of wetlands are having positive effects. But scientists agree that drastic measures will be needed to avert the ocean crises being created by climate change.
