What are the effects of biodiversity loss?
Biodiversity loss can have significant direct human health impacts if ecosystem services are no longer adequate to meet social needs. Indirectly, changes in ecosystem services affect livelihoods, income, local migration and, on occasion, may even cause or exacerbate political conflict.
What is the biggest threat to marine mammals?
The biggest threat to marine mammals worldwide is their accidental capture or entan- glement in fishing gear (known as bycatch), which kills hundreds of thousands of them each year.
What is marine biodiversity?
Marine biodiversity is an aggregation of highly inter-connected ecosystem components or features, encompassing all levels of biological organization from genes, species, populations to ecosystems, with the diversity of each level having structural and functional attributes (Table 1).
How does ocean pollution affect biodiversity?
Ocean pollution comes in many forms, but the largest factor affecting the oceans is plastic. … Plastic kills fish, birds, marine mammals and sea turtles, destroys habitats and even affects animals’ mating rituals, which can have devastating consequences and can wipe out entire species.
How does global warming affect ocean biodiversity?
Warmer waters cause coral bleaching, which in turn impacts coral reef ecosystems that are home to most of the ocean’s biodiversity — and provide crucial sources of food for people. Warmer waters threaten to cause mass migration of marine species in search of the right conditions for feeding and spawning.
