Plankton are microscopic organisms, key to the marine food chain, but research suggests they are in decline.

Predator removal can cause a cascading effect that destabilizes the entire marine food web and, in turn, our oceans.
CNN: Even after attacks on humans, sharks should be protected
It can adversely affect forests and crops, and is also linked with damage to plankton, the microscopic creatures at the bottom of the marine food chain.
Much of the pollution that exists in the garbage patches is plastic waste that gradually breaks down into short lengths of polymer which absorb other pollutants and accelerate their uptake into the marine food-chain.
The ocean absorbs close to 26 per cent of atmospheric carbon dioxide emissions which is provoking acidification that is already threatening some varieties of plankton and poses a threat to the entire marine food chain and dependant socio-economic activities.
In fact, this process is comparable to the use of fertilizers in agriculture, i.e. adding nutrients that are found to be lacking in the local environment to stimulate plant growth, in this case phytoplanckton that form the base of the marine food-chain.
The Marine Conservation Society says harvesting whitebait in large quantities reduces food supplies for other species - such as marine birds - in the food chain.
An unemployed former marine who uses the food bank said it would be "devastating" if it closed.
Estimated to be around the size of Texas, this contaminated area of ocean has by some estimates more plastic than food for marine life.
The workers also handed out campaign leaflets outside the Department of Agriculture, Food and the Marine in Dublin.
And when that plastic breaks down into tiny little pieces, it is often swallowed by marine creatures and enters the food chain.
The report asserts that the progressive unraveling of entire marine ecosystems up and down the food chain could lead to the "collapse" of all commercial species, possibly by the middle of this century.
These are: inland waterways, the promotion of the Irish and Ulster Scots languages, food safety, aquaculture and marine matters, trade and business development and special European Union programmes.
Ecosystem services provided by coastal and marine habitats are of crucial importance for food security and poverty eradication, as well as many of the sectors currently driving the economies of coastal nations.
They will implement all-island laws on inland waterways, the promotion of the Irish and Ulster Scots languages, food safety, aquaculture and marine matters, trade and business development and special European Union programmes.
Although the crocodiles spend most of their life in salt water, they are not considered marine animals as they rely on land for food and water.
If the ministers act on this recommendation, they will have plugged a vital gap in protecting the food supply of seabirds and other marine life from the threat of overfishing for sandeels.
Would we care more if we could see the higher concentrations of carbon dioxide being absorbed into our oceans, making seawater more acidic, endangering coral reefs and marine life and threatening to fundamentally disrupt ocean ecosystems and food webs?
Reinemund, a lean former Marine and sometime marathon runner, is no junk-food addict, but says that his wife, Gail, who is a big fan of Fritos, would never be caught dead eating a reduced-fat version of the snack if it were available.
"Marine life in the ocean are mistaking plastic for their natural food, " Lamson said.
CNN: Japanese tsunami debris makes its way into Hawaiian birds
One risk is that the mining operations could generate huge plumes of sediment that could drift through the sea - choking any marine life that feeds by ingesting water and filtering out its food sources.
BBC: UK Seabed Resources joins deep-ocean mineral-mining rush
This type of impact by top-of-the-food-chain predators on lower trophic levels is well known in marine systems, said Peterson, and has been shown to occur in terrestrial systems in the study of invertebrates.
Not only are they home to 25 percent of all marine fish species, but the organization states that 500 million people rely on coral reefs for their food and livelihoods.
