By the time we see that climate change is really bad, your ability to fix it is extremely limited... The carbon gets up there, but the heating effect is delayed. And then the effect of that heat on the species and ecosystem is delayed.
Thus, an average diet of 1,900 calories per day would dictate an intake of 1,900 ml (approximately 64 ounces) of water. However, people interpreted this as a recommendation to drink 1,900 ml of pure water, forgetting the fact that water is also found in abundance in the other liquids and foods we consume. So how much water should I really drink? Today, the NAM recommends letting thirst guide your water consumption habits but set an even higher volume of total daily water intake: 3.7 liters (15 cups) for the average adult male and 2.7 liters (11 cups) for the average adult female.
The typical U.S. adult downs about four cups a day, which is shy of the Institute of Medicine's recommendation to drink about three liters of fluid for men and 2.2 liters for women. But others disagree with this assessment -- if that's the amount of water a person naturally drinks in response to thirst, that's fine.
