hi mate,
according to news the National Academy of Sciences estimated that ocean-based sources, such as cargo ships and cruise liners had dumped 14 billion pounds of garbage into the ocean. Over 1 million seabirds and 100,000 sea mammals are killed by pollution every year.
Water pollution harms fish populations in various ways. ... Algal blooms can be harmful to fish as they feed upon algae, toxins accumulate within the fish, and when a predator fish consumes that fish, they too are consuming higher toxin levels. Pesticides and heavy metals that enter waterways can also harm or kill fish.
If untreated water keeps getting pumped into the lakes, it would soon contaminate groundwater resources, as is evident from the higher nitrate levels in the borewells in the vicinity of polluted lakes in Bengaluru. ... The fish would have got very weak because of the ammonia,” says Jamwal, who studies water pollution.
I hope it helps you.
