oceans

In the ocean, plankton is food.

There are two types of plankton – tiny plants (phytoplankton) and tiny animals (zooplankton).

Zooplankton includes some eggs and larvae of things like fish and crabs, as well as some minute animals that feed on phytoplankton. That makes them the first link in any food chain, and the basis for all of the ocean’s food webs.

We’ve sent thousands of emails, hundreds of tweets and inundated their Customer Service phone line with calls - but Sainsbury’s still won’t speak out against unsustainable fishing.
