Conserving marine biodiversity, avoiding species extinction and maintaining food security from wild capture fisheries can all be achieved simultaneously if a global, non-regionalized approach to marine spatial management is undertaken by the signatories of IUCN Resolution 50, which calls for the protection of 30 per cent of the ocean by 2030.

The tendency to place protected areas in habitats that are less attractive to humans because they are not very productive may be the reason why many species remain threatened and continue to decline.
To mark the sesquicentennial anniversary of Canada’s Confederation, the Peter Wall Institute is releasing, on June 23, the book Reflections of Canada: Illuminating our Biggest Possibilities and Challenges at 150 Years.
It is a provocative essay collection where leading writers, researchers, and public intellectuals peer into the country’s future within their individual areas of expertise. And, who better than the Sea Around Us Principal Investigator, Daniel Pauly; the Nereus Program Science Director, William Cheung; and OceanCanada‘s Director, Rashid Sumaila, to talk about what the upcoming years might look like for Canada’s fisheries?

Highly protected marine reserves can help mitigate against the impacts of climate change, a study by a team of international scientists has concluded.
Scientists say reserves can help marine ecosystems counter fight five key impacts of climate change: ocean acidification; sea-level rise; increased intensity of storms; shifts in species distribution, and decreased productivity and oxygen availability.

Yes, the 6th Extinction is underway, and we are going to lose quite a bit of the Earth’s biodiversity, both terrestrial and marine, because of our agriculture, our fisheries, and because there are so many of us. But we should try to minimize the loss, using all the tools at our disposal.
One of these tools is slowing down, or even reversing, the rate at which we expand into and thus transform and ultimately destroy natural ecosystems and their biodiversity. On land, this consists of creating parks where the natural vegetative cover, notably forests, can maintain or reestablish itself, and provide habitats for animals that cannot live in landscapes shaped by agriculture.
