Introduction
Rapid growth of population reaches a threatening intensity when rate of growth significantly surpasses the anticipated increases in resources, death rate, and land space. A considerable increase in fertility distorts the balance of population and has the capacity of influencing several fundamental areas of the social order and the economy. The effects vary from a short period scarcity to long-term consequences, affecting the upcoming generations. The evolution of human beings has reached a phase of scientific advancement and prosperity with the population of the world also expanding rapidly. In slight developed periods, more individuals succumbed to diseases. Currently, owing to medical progresses, individuals live longer, a ground to the growing population. This nature of growth has resulted in problems such as the demands created on the resources of the planet along with congestion. According to a population growth theory by Malthus, the nature of population growth is exponential as an unconstrained population ultimately contributes to poverty, unrest owing to an increase in supply of labor, and wages sprawling.
The estimation of the global population points out to an annual increase of 2 percent. Ultimately, the trends of growth result in adverse consequences on the world’s resources and landscape. Presently, the population on Earth increases exponentially daily. The extra people there are the further resources required. Regrettably, most of the resources human beings depend on presently are not renewable. Food can be renewable, but food production requires water, land, and energy. Studies and researches also indicate that energy is renewable even though corporations, politicians, and lobbyists stand in the way of shift towards renewable energy on both national and international levels. Even so, nearly all of the required resources have the capacity of being renewable following agreements on the best means of carrying out the process, consequently setting the wheels in motion. Space is an exception as there cannot be additional creation of spaces on Earth.
At the point of running out of space, perhaps going into the outer space will be the only alternative, which is an extremely challenging and expensive endeavor. Particularly with increasing tendencies of consumption seen in developed nations eventually sustaining production of food to meet, the growing demand will be impossible. There will be a continued decrease in land availability for agriculture and a decline in cattle grazing. Harvesting of the forests has resulted in erosions and degradation of land. The latter strips the soil of nutrients and restricts it from further grazing and agriculture. Erosion leaves minimal land for producing food consequently contributing to floods and has the capacity of damaging coral reefs. Renewable fresh water supply per capita also decreases at a rate not sustainable. The contributing factors to the decrease in water supply include over developments, exhaustion of natural aquifers, and acid rains resulting from air pollutions. An escalating world populace will lack access to electricity or extra sources of energy at present production of energy and rates of usage.
Conclusion
The hastening growth of population on Earth perhaps encompasses several consequences. All the species on the planet have a population limit of growth. Any species surpassing the limit, the wellbeing of the earth, other species, along with the overpopulated species face risks. Failure of human population growth will result in the humanity encountering extremely tough choices. Review of the population growth consequences can be of assistance to humanity finding solutions to the predicaments prior to the influence on the world becoming irreversible.
