The idea of carrying capacity
The idea of carrying capacity
‘By the end of the 21st century, human population growth may exceed Earths carrying capacity. Discuss.
The idea of carrying capacity is not a new one. Carrying capacity is the maximum population size that the environment can support without deterioration (McGraw-Hill, 2002). The first idea of carrying capacity applied to natural organisms was introduced in the 1980s so the concept that the earth is a ship with only enough food and resources to be able to sustain a finite population is not new (Sayre 2007).
The population of Earth currently stands at around 6.8 billion and is expected to reach 7 billion by the year 2011. In just 12 years, the population of earth has risen by nearly 1 billion after a population of 6 billion was reached in 1999 (Unknown 2009). Population has been projected; and estimated to reach 9.4 billion by 2050. (Ehrlich.P, A 2009). The rate at which population is increasing causes a growing concern with the carrying capacity of the planet and whether or not the planet will be able to sustain the population.
