Overpopulation is a situation where people in a particular country are many in relation to the available resources; it is also a situation whereby the population of a country is above the optimum population. Ehrlich describe as 'turning the Earth into a giant human feedlot' could be severe. This applies even to the public transport system and places like parks, hotels, halls etc.
Without the balance achieved from the predator-prey relationship, overpopulated herbivores will compete for the same plant species, causing scarcity, or wiping out the plant species entirely.
