Wetlands are like a bank for holding water: During floods, they absorb water and reduce flood damage. Dur-­ ing droughts (times of below-normal rainfall) they provide water to streams. Water in wetlands seeps into the soil to recharge groundwater supplies. Many plants and animals depend on wetlands for their food and their living environment, known as habitat. Wetlands also serve as nurseries for young animals, including commercially valuable fish and shellfish species. As water trickles through wetlands, the rich soil filters pollutants.

Humans are also ingenious: If a resource is depleted, they can find other ways to obtain it, or they can substitute a different resource. For example, if water is in short supply, but energy is abundant and cheap, humans can create drinking water by building plants to desali­ nate seawater. Humans undoubtedly exceed the carrying capacity of some regions—sub-­Saharan Africa, a region of chronic hunger and overpopulation, is one ­example. Overpopulation ­Debate Debate about overpopulation likely began with an essay written by the Reverend Thomas Malthus (1766–1834) and published in 1798 (when 17 18 humans and the natural environment world population was 978 million).
