Macroalgae can produce between 2 and 14 kilograms, whereas terrestrial plants, such as trees and grasses in temperate climates, and microalgae can generate only about 1 kilogram. By James Jungwirth. The overall effect of seaweeds on the global ecosystem is enormous. We also have to examine how seaweed farming would impact marine mammal diversity and potentially contribute to ocean pollution. Jennifer Kennedy, M.S., is an environmental educator specializing in marine life. It has also been an integral part of human diets for thousands of years. So, "farming" algae might lead to those algae absorbing CO2. Its thick stems protect it from the corrosive salt water. Made of interconnected food chains, food webs help us understand how changes to ecosystems say, removing a top predator or adding nutrients affect many different species, both directly and indirectly. Slimy, stinky brown seaweed that ruins beachgoers' vacations from Mexico to Florida may be the new normal unless Brazil halts Amazon deforestation, experts say.
