Document Summary
Habitat degradation and loss happens when aquatic environments (or ecological set-up) becomes unable to support life due to degradation. Extreme weather events damage coral reefs and shoreline habitat. Ocean acidification due to increased atmospheric co2. Temperature increases, leads to coral bleaching, >70% reef mortality. Affects on temperature specific life- history traits. Pollution is substances or energy introduced by humans that change/affect the physical, chemical, or biological environment. Point source: any single identifiable source of pollution from which pollutants are discharged. The pollution can be traced back to exactly one source. Nonpoint source: no single identifiable source of pollution. It could be coming from multiple sources; no one can pin it down to one source. Far reaching effects: ex: mercury increases up the food chain. Covering aquatic substrate: (cid:862)s(cid:373)all(cid:863) s(cid:272)ale proje(cid:272)ts like the palm tree island in dubai, large scale land recovery like the. Under the right conditions, it grows in large colonies.
