Which sentences correctly describes the effect of marine debris? Marine debris is very harmful to marine life. Its effect, however, is only limited to marine creatures, as it does not affect birds and other species
that depend on the sea. One of the major contributors to marine debris is plastic. Garbage and litter from the beach does not contribute to
marine debris. Research shows that marine debris is likely to decrease over time as plastics degrade into smaller particles. New methods of
manufacturing have been adopted to reduce material consumption and thus prevent a larger contribution to marine debris.

Over the past 60 years, many amphibian species have experienced significant population declines and some species have become extinct. scientists suspected that local human activities such as the destruction of wetlands, regional pollution, and deforestation were the main reasons for these losses. however, research over the past 20 years reveals significant amphibian population declines in protected areas of the world, such as nature preserves and parks. these global declines suggest widespread problems including increased ultraviolet radiation, acid rain, and disease. in switzerland, for example, 14 of the 20 native amphibian species are threatened with extinction. chytridiomycosis is a fungal disease first identified in 1998 as a cause of massive amphibian deaths. in some severely impacted populations, a few individuals have survived, perhaps because of some natural resistance. if these resistant individuals continue to survive and prosper, new resistant populations might emerge. this would be an example of the founder effect artificial selection genetic drift natural selection sexual selection
