Algae are sim­ple plants that can range from the mi­cro­scopic to large sea­weeds.

Blue-green algae, or cyanobac­te­ria, are an an­cient group of algae that can re­pro­duce rapidly in lakes and ponds.

Blue-green algae blooms may look like thick pea soup, green paint or ap­pear a dif­fer­ent colour such as bluish, brown­ish or red­dish green.

When a blue-green algae bloom washes up on shore, it can form a thick mat or a foam on the beach.

Algae are very di­verse and found al­most ev­ery­where on the planet. They play an im­por­tant role in many ecosys­tems, in­clud­ing pro­vid­ing the foun­da­tion for the aquatic food chains sup­port­ing all fish­eries in the oceans and in­land, as well as pro­duc­ing about 70% of all the oxy­gen we breathe.
