The Issues: Oceans

Oceans are a huge storehouse for carbon and exert a huge influence on our climate. We need to ensure the continued health of ocean systems as a buffer against climate change, as an important global food source, and as a biodiversity reservoir. Without action to address climate change, oceans will become increasingly acidified (from increased CO2), their habitats will likely become less productive, and their water levels will rise -- threatening coastal areas and low-lying islands.

For species such as salmon, warming oceans are adding to the stress already caused by over harvesting. In fact, the greatest current threat to marine biodiversity remains over-fishing -- recent studies have shown that the majority of large fish in the sea are gone. However, human activities like aquaculture and coastal oil drilling are also expanding and creating serious environmental challenges for ocean species.

We need to stop thinking of oceans as simply water and start seeing them as complex ecosystems that, just like land-based systems, can benefit from intelligent planning and the creation of protected areas.

Unfortunately, Canada's progress on meeting its national and international commitments to protecting marine life has been excruciatingly slow. We will need to turn the current ripples of action into a tidal wave of activity if we are going to meet commitments like completing a national network of marine protected areas by 2012. A good start for the federal government would be to accelerate the implementation of the Oceans Actwith adequate funding.

Canada also needs to address domestic over-fishing in our waters, and the serious impacts of fishing gear on marine habitats and sensitive areas. Bottom trawling is particularly harmful, damaging large areas of marine habitat, catching huge numbers of unwanted fish that are then discarded, and consuming more fossil fuel per tonne of fish captured than any other fishing method.
