Every organism we know of needs water to survive. In fact, without water, life on Earth would have never begun. From simple organisms to complex plants and animals, water has played a critical role in survival. In humans, it acts as both a solvent and a delivery mechanism, dissolving essential vitamins and nutrients from food and delivering them to cells. In addition, our bodies use water to flush out toxins, regulate body temperature and aid our metabolism. Besides being essential for our bodies to function, water also promotes life in numerous other ways. Without it, we couldn't grow crops, keep livestock or wash our food. Water has also advanced civilization, providing a means for travel for entire parts of the world and a source of power for factories. Because water can also exist as a vapor, it can be stored in the atmosphere and be delivered as rain across the planet. Earth's oceans also help regulate the planet's climate absorbing heat in the summer and releasing it during the winter. And of course, those same oceans serve as a home for countless plants and animals. In my opinion, water is a nonrenewable resource. Although Earth is mainly water, only 3% of that water is drinkable which will slowly decrease in amount as living beings continue to drink it. In addition, since there is exponential growth in population, we will use up more water even faster. Thus, water should not be considered as a renewable resource due to its temporary vast amount, but rather as a nonrenewable resource that is steadily decreasing as time go by.
