主題：Do you think that human activity is posing a threat to the oceans of the world?

There is no doubt that humans have had a huge impact on the ocean. In fact, evidence of humans can be found all over the oceans, even in the most remote polar areas, in the form of floating trash. Human acts are posing major threats to marine systems, which I believe we eventually will have to pay the price.

Posing a threat to: 造成威脅
Impact: 影響
Remote: 偏遠的
Polar area: 極地
Float: 漂浮的
Trash: 垃圾
Marine system: 海洋系統
Pay the price: 付出代價
