In many freshwater ecosystems, phosphorus is the key limiting nutrient, but when it becomes overabundant due to human activity, it triggers devastating ecological consequences. This phenomenon reveals a critical paradox: what happens when there is too much of a limiting nutrient, disrupting the delicate balance of life it once controlled?.

According to the Centers for Disease Control and Prevention, paralytic shellfish poisoning (PSP), caused by saxitoxin, is one of the most common and severe forms of seafood-related food poisoning. This potent neurotoxin is produced by certain types of marine algae, which are then consumed by filter-feeding marine life, concentrating the toxin in their tissues. The primary concern for human health is the consumption of seafood contaminated with saxitoxin.
