living thing is a kind of organism & as a population of organisms increases , the resources used by those organisms will decrease -> as a engineer of inanimate nothing increases, the advances used by those inanimate nothing 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 & living things require water for survival & 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  as a cost of inanimate nothing increases, the land used by those inanimate nothing will increase & if the amount of something decreases then that something might be depleted -> as a population of a living thing increases the water used by those living things might be depleted as a population of a living thing increases the water used by those living things might be depleted  a desert environment is low in availability of water / availability of food & 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 water is more likely to be depleted in a desert environment  as a molecules of a inanimate place topsoil the land used by those inanimate nothing weak 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
