About Seaweeds

Seaweeds are marine algae found in coastal environments, including intertidal zones and shallow waters.
They are classified into three main groups: green (Chlorophyta), red (Rhodophyta) and brown (Phaeophyta) algae.
Seaweeds serve as a crucial food source for various marine animals, including Herbivorous Fish, Sea urchins, crabs, snails, Manatees etc.

Carbon Sequestration: Seaweeds absorb CO₂ from the atmosphere, contributing to climate change mitigation. They help to lower ocean surface CO₂ levels.
Habitat Creation: Seaweed beds provide essential habitats for various marine species, enhancing biodiversity
Culinary Uses: Seaweeds are consumed directly as food (e.g. nori, kombu)
Pharmaceuticals and Cosmetics: Extracts from seaweeds are used in many products for their thickening and gelling properties.
Biofuels: Seaweeds can be processed into biofuels, offering a sustainable alternative to fossil fuels without requiring arable land or freshwater.
Animal Feed: Incorporating seaweed into livestock feed can reduce methane emissions from ruminants, contributing to more sustainable farming practices.
