Warmer seas put marine food chain at risk
Warmer seas put marine food chain at risk

A study published in the journal Nature finds a strong link between higher sea surface temperatures and a major decline in phytoplankton, which forms the base of the marine food chain.
The three-year study by Canadian scientists at Dalhousie University in Halifax, Nova Scotia, reveals the crucial marine species is dying, which could significantly change the way humans live.
The study suggests phytoplankton have declined by roughly 40 per cent since 1950, most likely because of rising sea surface temperatures and changing ocean conditions.
Phytoplankton are important because they generate roughly half of all organic matter on the planet and produce half the world’s oxygen.
