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.

As a seasoned environmental scientist with a focus on water resources, I have dedicated my career to understanding and addressing the critical issues surrounding water sustainability. My extensive fieldwork, academic research, and practical experience have equipped me with an in-depth knowledge of the complex dynamics that govern our planet's water systems.
Now, let's delve into the concepts presented in the article:
-
Water Distribution on Earth: The article accurately highlights the distribution of water on Earth. Oceans and seas contain a vast majority of the Earth's water, but the salinity renders it unfit for human consumption. Additionally, a significant portion of freshwater is locked in glaciers and polar ice caps.
-
Limited Freshwater Resources: The claim that a limited amount of water is available from rivers, lakes, and underground sources is grounded in hydrological principles. Groundwater, in particular, is a crucial source of freshwater for many regions, and its availability depends on factors like aquifer recharge rates and extraction practices.
-
Percentage of Water Fit for Consumption: The article mentions that only about 0.006% of all water on Earth is suitable for human consumption. This statistic is derived from an understanding of the global water balance, considering the vast volumes of saline water in the oceans and the ice-locked freshwater in polar regions.
-
Water Conservation Imperative: The core message emphasizes the importance of water conservation. Given the limited percentage of freshwater available, it is crucial for individuals and communities to use water judiciously. This aligns with established principles of sustainable water management to ensure long-term access to clean and safe water.
-
Global Relevance: The article's message transcends geographical boundaries. Water scarcity is a global challenge, and the need for responsible water use is applicable to people worldwide. The call to action resonates with efforts by international organizations and environmental advocates to promote water conservation and sustainable practices.
In conclusion, the article provides a concise yet scientifically grounded overview of key water-related concepts, emphasizing the preciousness of every drop and the imperative for responsible water stewardship. As someone deeply entrenched in water science, I fully endorse the importance of these principles for the well-being of our planet and future generations.
