Populations of organisms are usually restricted in their size by limiting factors, such as the availability of food or light. these factors maintain the size of a population at a fairly constant level. if the limiting factors are removed, the population is able to grow very rapidly. this is clearly demonstrated if a small number of bacterial cells are inoculated into a nutrient broth, and the number of cells is monitored for several hours.
The human population on Earth has increased at an astounding rate ever since the Industrial Evolution. New technologies and systems of agriculture have allowed the human race to keep building their numbers, but when will the carrying capacity of Earth be reached? Better yet, how can the large populations of the future sustain themselves by the Earth they walk on and still manage to preserve the land for future generations? The answer is not as clear-cut as the average person thinks: instead of using more farm land to increase agricultural production, environmentally-safe agriculture efficiency must be increased in the already-cultivated areas of the Earth. The world can continue to grow and thrive with a growing population by utilizing more agricultural product for food instead of other uses, by reducing waste in the food crops that are being produced, and by decreasing yield gaps.
Water shortages, pollution and growing population threaten a finite and necessary resource and the billions of people who depend on it.
