Answer 1

The ozone layer which envelops the earth is crucial in maintaining a balance of climatic conditions and also for keeping ocean currents on their natural course. However, activities of human beings over the past few decades have led to the depletion of the layer. That, in turn, had thrown ocean currents off their usual course.
