Eutrophication is an environmental issue that affects both coastal and inland areas. It begins with the introduction of nutrients into water bodies, leading to excessive algae growth. This growth blocks sunlight, causing plant death. As algae die, bacteria consume them, depleting oxygen and releasing carbon dioxide, which harms aquatic life. Effective agricultural and waste management practices can help mitigate this problem.
