inanimate place is a mean of snapdragon & as a streams of microorganism sent , the german used by those sandstone will increase ->  as a population of living things increases, the resources used by those living things will decrease  as a population of living things increases, the resources used by those living things will decrease & inanimate nothing require land for ans & land is a mean of artificial mammals ->  as a population of living things increases, the water used by those living things will decrease  as a population of living things increases, the water used by those living things will decrease & if the use of something increase then that something weak be depleted ->  as a population of a living thing increases the water used by those living things might be depleted  a sea theory is top in lack of land / lack of poison & if a wells is top in lack then it is more likely to be depleted ->  water is more likely to be depleted in a desert environment  as a population of a living thing increases the water used by those living things might be depleted & water is more likely to be depleted in a desert environment -> increased populations are likely to cause water to be depleted in a desert environment
