The introduction of plastics in to the marine environment has also contributed to what other damages to planetary boundaries. Mark all that apply

a. Biodiversity loss due to marine animals which are killed through entagling in or consuming plastic waste which reaches the ocean.

b. Biomagnification of mercury pollution in to the food chain through microplastics which absorb the mercury and are then

consumed.

c. An increase in ocean acidification through plastics leeching low pH contaminants in to the water.

d. An increase in carbon dioxide emissions which contribute to climate change through the use of fossil fuels in producing and

shipping plastic products.

Option-A,B and D

Explanation:

Plastic pollution is one of the major threat to the ecosystem on Earth. The increased amount of plastic in the ocean has affected the aquatic ecosystem as it is the cause of the increased number of aquatic animals.

The animals consume the floating plastic of the ocean or get entangled in plastic waste.

The consumed plastic waste becomes a threat to these individuals. The microplastic consumed by the fishes, crabs can disrupt the food chain as it can cause biomagnification.

The plastic products production and transport to various parts of the world also cause harm as these activities involve the use of fossil fuels which leads to an increase in the concentration of carbon dioxide.

Thus, the selected options are correct.
