Answer 2

Ocean currents balance out the North-South temperature and provides oxygen to the deeper parts of the oceans. In the days of sailing ships they were used for travel.

Global warming threatens ocean currenrs. If the major ocean currents go away the climate near the equator will heat up, and the North will cool down. Additionally, the ocean losing oxygen in the deep parts would threaten the variety of life in the depths and the aerobic bacteria life required for oxygen generation on the surface. The lack of aerobic life can facilitate the growth of anaerobic life which exhale poisonous gas.
