Even though algae plays an important role in a balanced ecosystem, if they are kept unchecked they could release toxins that can have horrible effects on humans, plants, and animals.  Since there are a supply of excess algae, why not put it into good use? A footwear brand and an algae harvesting business teamed up to put the excess algae to good use. Transforming algae into foam helps clean bodies of water that are clogged with harmful algal blooms. These thick clouds of algae release a toxin called domoic acid, which accumulates in small fish like sardines and anchovies and then moves up the marine food chain. Eating seafood contaminated with domoic acid can cause people to experience nausea and vomiting. So staying away from petroleum based products isn't the only upside.
