Question

Suppose scientists decided to harvest the mineral nodules on the sea floor. Identify two environmental problems that might occur if the nodules are harvested.

Answer 1

Answer:

Disturbance to deep sea bed and biodiversity

Explanation:

Harvesting of mineral nodules on the sea floor is done by deep sea mining.

The adverse impacts of deep sea mining are as follows -

Degradation of habitat of ocean species living at the sea bed.

Degradation of habitat causes extinction of species

Noise pollution under the sea

Plumes of suspended sediments  

Disturbance in the ecosystem

Answer 2

Mining might disturb the environment on the bottom and kill benthic organisms. Cold water from the deep part of the ocean might be brought to the surface, killing warm-water species.
