'Every Drop Counts' is a slogan related to
(a) counting of drops of any liquid
(b) counting of water drops
(c) importance of water
(d) importance of counting
The answer is option (c).
Every drop of water is precious for life to sustain on earth. Most of the water present on earth is not fit for consumption by us. Sea and oceans contain salty water which cannot be used for human consumption. Even most of the fresh water is frozen as ice in glaciers and polar regions. Hence, we are left with a limited amount of water from river, lake and from under the ground. Thus, the percentage of water for consumption is roughly 0.006% of all water found on the earth. So, we should not waste water, should use it judiciously.
