Question

13 directions: select each correct answer. more than one answer may be correct. marine biologists predict that by the year 2100 a cascade of extinction events could eliminate more than half of the worlds marine species. marine ecosystems are crucial to humans because they produce more than half of all oxygen in the atmosphere, absorb more carbon dioxide than forests, and provide a variety of marine animals that humans consume as food. the decline of marine biodiversity is a looming, worldwide problem that is closely linked with human activity. examples of such activities include overfishing to the point of fishery collapse, the use of large driftnets that catch unintended organisms, and the pollution of marine ecosystems. such a complex problem would be difficult to solve without breaking it up into smaller, more manageable problems. which of the following engineering solutions would help prevent the further decline of marine biodiversity? a water treatment process that neutralizes pollution and balances the ph of wastewater an effective fishing net that traps fewer unwanted organisms a generator that uses seawater to produce breathable oxygen a computer program that can predict fish populations and help prevent fishery collapse

Explanation:

• A water - treatment process that neutralizes pollution and balances the pH of wastewater can reduce pollution in marine ecosystems, thus helping to prevent the decline of marine biodiversity.
• An effective fishing net that traps fewer unwanted organisms can reduce non - target species death, protecting marine biodiversity.
• A computer program that can predict fish populations and help prevent fishery collapse can avoid overfishing, which is beneficial for marine biodiversity. A generator that uses seawater to produce breathable oxygen does not directly address the issues causing the decline of marine biodiversity such as overfishing, by - catch, and pollution.

Answer:

A. a water treatment process that neutralizes pollution and balances the pH of wastewater
B. an effective fishing net that traps fewer unwanted organisms
D. a computer program that can predict fish populations and help prevent fishery collapse
