Elephants consume impressive quantities of food: between 150 and 300
kilograms daily. If they have free access to water, they will drink as much
as 180 to 220 litres of water per day.
An adult elephant, therefore, produces between 140 and 140 kilograms of
dung. Elephants also eat a wider variety of plants than any other herbivore
in the region, and spend much of their time foraging.
Large populations of elephants can alter and damage their environment
significantly by their feeding methods so that a careful control of
population sizes and densities is necessary.
