Waste Management — I Impact of Waste Accumulation — Question 19

(i) 'Use and throw' concept generates more waste because this concepts means to use any product only once and then dispose it. Therefore, after using a product only once, it is neither re-used nor recycled, but disposed once and for all. And since people are using this concept in modern times, the generation of waste is increasing to new levels.

(ii) Run off from fields leads to death in adjacent water bodies because the fertilisers and pesticides used in the fields have chemicals. When they reach the water bodies, the toxins present in the waste can kill aquatic organisms directly by sufficiently changing the pH of water, covering the water surface and causing a reduction in dissolved oxygen. The aquatic organisms may also become victims of bio-magnification and bio-accumulation.

(iii) Birds feeding on agricultural waste are at the brink of extinction because feeding on agricultural waste affects them adversely. Such birds have thinner and weaker egg shells and increased mortality.
