Thanks to the actions taken so far, the threat of whaling and hunting for other marine species has been significantly reduced. There are also some positive effects of the restrictions imposed on fishing, although here the pressure on life in the oceans is enormous. However, for several decades, the threat of climate change has been growing rapidly, and secondly, pollution of the oceans with chemicals and plastic. However, even despite our unsustainable maritime economy, the oceans are so large and, at times, inaccessible that many of their areas are still untouched by man. Moreover, numerous examples show that life under water can be reborn if we eliminate threats and give it the conditions to do so.

Some of these examples are known from the history: the rebirth of fish populations during both world wars, when fishing was restricted; the reconstruction of coral reefs in the Marshall Islands area after nuclear weapons tests; the improvement of the condition of the Black Sea after the collapse of the USSR and the consequent reduction in the amount of fertilizer that entered the water. This, of course, is a side effect of these events, but deliberate actions for nature conservation also have an effect.
