Balance of nature

The balance of nature, also known as ecological balance, is a theory that proposes that ecological systems are usually in a stable equilibrium or homeostasis, which is to say that a small change (the size of a particular population, for example) will be corrected by some negative feedback that will bring the parameter back to its original "point of balance" with the rest of the system. The balance is sometimes depicted as easily disturbed and delicate, while other times it is inversely portrayed as powerful enough to correct any imbalances by itself.[1] The concept has been described as "normative", as well as teleological, as it makes a claim about how nature should be: nature is balanced because "it is supposed to be balanced".[2] The theory has been employed to describe how populations depend on each other, for example in predator-prey systems, or relationships between herbivores and their food source.[3] It is also sometimes applied to the relationship between the Earth's ecosystem, the composition of the atmosphere, and weather.[4]

The balance of nature, as a theory, has been largely discredited by scientists working in ecology, as it has been found that constant disturbances leading to chaotic and dynamic changes are the norm in nature.[5] During the later half of the 20th century, it was superseded by catastrophe theory, chaos theory, and thermodynamics.[6] Nevertheless, the idea maintains popularity amongst the general public.[7][8]
