The pie charts A and B shown in Fig. 16.1 are based on waste segregation method adopted by two families X and Y respectively.

Which of the two families X or Y do you think is more environmentally conscious and why?

Family X is more environmentally conscious because this family disposes kitchen wastes and polythene bags separately. Kitchen wastes are biodegradable and can be converted into compost which can be used as a manure. But polythene bags are non-biodegradable hence should be separated from kitchen wastes.
