The study is a work of information on 17 different types of at-sea activities, including various kinds of fishing, climate change, shipping, and pollution. The study discovered that almost half of the world’s oceans have now been heavily affected by humans. But the heavily affected waters are around Nova Scotia and Newfoundland.
Carrie Kappel of the National Centre for Ecological Analysis and Synthesis at the University of California in Santa Barbara, said that these areas are subject to high levels of a variety of different types of artisanal and commercial fishing both demersal, or bottom fishing, and pelagic, or open water fisheries, runoff of inorganic pollutants from land and ocean-based pollutants from ships at sea, commercial shipping activity, and invasive species.
She said that the waters around Newfoundland and Nova Scotia have particular ecosystems, such as rocky reefs, that are vulnerable to the impacts of a lot of these activities. As per the study more than 40 per cent of the world’s oceans have been heavily affected by humans.
According to the researchers the coral reefs, seagrass beds, mangroves, rocky reefs and shelves, and seamounts in that areas were also greatly affected. Kappel hoped that the study will work as eye opener to save our waters.
