We all know the world has its problems, particularly where the environment is concerned.  this can occur through the release of industrial waste, for example from mining and metal refining activities, into streams and rivers, from where it may make its way into the ocean. a variety of toxic metals can affect aquatic and marine life and may accumulate in the food chain, posing a threat to humans. another major source of water pollution is fertilizers, which can be washed into rivers and lakes from farmland, causing a phenomenon known as eutrophication. nitrates and phosphates, present in fertilizers, and essential for plant growth, can also promote uncontrolled multiplication of  algae  in lakes, causing an “algal bloom.” this reduces water quality and  oxygen  levels, and may kill fish.  мы все знаем, что мир имеет свои проблемы, особенно если речь идет о окружающей среде. это может произойти в результате выброса промышленных отходов, например, от горнодобывающей и металлургической деятельности по переработке нефти, в ручьи и реки, где он может внести свой путь в океане.разнообразие токсичных металлов могут повлиять на водной и морской жизни и может накапливаться в пищевой цепи, что создает угрозу для людей. еще одним важным источником загрязнения воды является удобрения, которые можно стирать в реки и озера от сельскохозяйственных угодий, в результате чего явление, известное под названием эвтрофикации. нитраты и фосфаты, присутствующие в удобрениях, и необходимые для роста растений, а также может способствовать неконтролируемому размножению водорослей в озерах, вызывая "цветение воды". это снижает качество воды и кислорода уровни, и может убить рыбу.
