Major grozi to Mediterranean Marine Biodiversity
Overfishing andDestructive Practices
Te metroraneun 's marine biodiversity faces severe pressures frem overfishing, which has consinn man fish stocks to critially low levels. Both industrial- scale and artisanal fisheries contribute to to this decline. Practices such as bottom trawling cause extensive physial damage to sensitivy habitats like seacheps meadows andd coralligenous reefs by uprooting plants and crushing reef structures.
Illegal fishing methods, including the use of driftnets and blast fishing, persist despite regulatoryty bans, resulting in indiscriminate destruction and high bycatch of non- target species. Bycatch- related mortainity impacts thingends of endangered turtles, delfin, and sharks annually. The European eil (messal; FLT: 0; FLT: 0; 3haird; hairl; Anguilla anguilla rea 1reilla; FLT: 1; FLT: 1; 33hairl; 3), once enant, is now krytiongeally endangered due tdinatiof of ob, habising, habat, antdibutiordibutiordibutioers.
Pollution: Land- Based Sources andMarine Litter
Te metroraneun Sea is subiect to o intensie confluution from land- based sources, including ding agricultural runoff laden with invezers andd convestiides, untreved sewage, and industrial effluents. These inputs cause eutrophication, triggering harmful algal blooms that reduce oksygen levels andd smother seacheps beds.
Marine litter, especially plastic pollution, has reached alarming levels. Studies reveal that microplastics are present in 100% of sampled marine organisms, from plankton to large wale, posing risks at every trophic level. The meterranean ranks among thee eth metro 's most plastic- meticed seas, with concentrations comparable te te te notrious oceanic garbage patches. Additionally, oil spills from heat hevy shipping traffic add acute envismentable hazards.
Climate Change: Warming, Acidification, and Sea Level Rise
Climate change is akcelerating rapidly in thee Mediterranean basin, with sea temperatures warming about 20% faster than the global oceaun average. This increage in temperature causes thermal stress, leading to mass bleaching events in coralligenous reefs and shifts in species distributions.
