Phytoplankton might be too small to see with the naked eye, but they are the foundations of the ocean food chain, ultimately capturing the energy that sustains the seas' great beasts such as whales.
A new study though has raised the alarm about fundamental changes to life underwater. It warns that populations of these microscopic organisms have plummeted in the last century, and the rate of loss has increased in recent years.
The reduction – averaging about 1% per year – is related to increasing sea surface temperatures, says the paper, published tomorrow in the journal Nature.
The decline of these tiny plankton will have impacted nearly all sea creatures and will also have affected fish stocks.
