Types of Habitat Destruction
Pollution
Ocean Acidification
Habitat Degradation
Destructive Fishing
Habitat Fragmentation
Parts of the habitat are destroyed which leaves small pieces behind (Martin, 2018)
Leaves marine life with less space to find survival needs
Damages marine life ability to adapt to the constant changing environment
Increases the vulnerability for invasion by exotic native species (Henry, 2024)
There are 4 different effects of fragmentation is 1-reduction in habitat amount, 2-increase in the number of fragments, 3-decrease in fragment size, 4-increase in fragment isolation (Hagen, 2012)
‘Processes of human origin that make habitats less suitable or less available to cetaceans.’ (IWC, 2024).
Consequence of human activities that alter the sea-floor and the release of pollution (UGC, 2022).
Habitats are degraded when there is overfishing, pollution, mining, and climate change
Can no longer support marine life - such as corals/ reef
Coral areas are suffering the most due to habitat degradation
Plastic is the main pollution in the ocean
Some types of pollution are plastic, ferilizer runoff, nonpoint sources, light, noise, and industrial chemicals (Howell, 2024).
Marine debris comes from things that people do on land
The chemicals that are found in sunscreen are actually harmful to the coral reefs and they end up destroying the coral
88% of the sea’s surface is polluted by plastic and that correlates to anywhere around 8-14 million tons of plastic that go intp the ocean each year (Condor, 2023).
Methods are using explosives to kill, longline, drift netting, gillnets
It is slowly killing off the marine life and in return is causing us to lose our resources that we get in return
Also affects coral life because we are using multiple methods that are killing the coral
The most destructive fishing is bottom trawling which is a method that drags a large net all across the sea floor (Marine, 2023)
Poople are taking the fish and marine life into their own home, lakes, and ponds for their own benefit and are taking these things from their natural habitat
Reduction in the pH of the ocean over time, caused by the increase of CO2 that is caused by global warming and climate change (NOAA, 2012).
CO2 is being absorbed by the seawater and it is absorbing about 30% of the CO2 that is being released (NOAA, 2012).
Coral and planktons are having trople shedding and form their new shells
Most severe in the Arctic and Antarctic polar oceans
Deeper water in the ocean is actually more acidic than the surface water of the ocean
