(A) (D) disposal into water without proper treatment may cause outbreak of serious diseases such as, dysentery, typhoid, janudice, cholera etc.
(B) High concentration of \( \frac{\text { ( }}{} \) distrubs (ID) metabolism in birds, which causes thinning of eggshell and their premature breaking, eventually causing decline in bird populations
(C) Without greenhouse effect, the average temperature at surface of earth would have average of \( 15^{\circ} \mathrm{C} \)
(D) Presence of large amounts of nutrient in waters also causes excessive growth of free-floating \( (\mathrm{D} \) - called an (ID) bloom, which imparts a distinct colour of the water bodies. (III) causes deterioration of the water quality and fish mortality. Some bloom-forming algee are extermely toxic to human beings and animals
