<human>: Is it true that the world's oceans are dying?
<bot>: Yes, it is true that the world’s oceans are dying. The ocean’s ecosystem has been in decline since the 1980s due to pollution and overfishing. In addition, rising temperatures caused by climate change have led to an increase in acidification of the ocean, which can cause a decrease in biodiversity. These factors combined have led to a dramatic decrease in fish populations, as well as other marine life such as coral reefs, whales, and seabirds.
