The global population is growing unabatedly like a wildfire despite several regulatory measures by every country and the global organizations working on it. Now a new study has brought some glaring exposures about the world demography.
According to the scientists, the problem of rising population will continue as even stern restrictions over the catastrophic event or fertility have failed -and will most likely remain ineffective- in reducing the world population.
The study researchers– Ecology professors Corey Bradshaw and Barry Brook from the Environment Institute at University of Adelaid– said that the “virtually locked-in” growing population is a wake-up call for all the world leaders that they must focus on renewing policies and making best use of technologies in reversing the rising consumption of natural resources and enhance recycling, for more instant sustainability gains.
The world population had increased so fast over the past century that around 14 percent of all the humans that were ever in existence were still alive today, Professor Bradshaw said.
According to Professor Bradshaw, this growing phenomenon of population was unsustainable for many reasons, including the impact on the climate and environment.
For the study, the researchers analysed various scenarios for changing global human population to the year 2100 with the help of adjusting fertility and mortality rates. This also helped them to determine the reasonable range of population sizes towards the end of this century.
The researchers said that the problem of growing population is so immense that not even policies like China’s one-child policy or catastrophic mortality natural events like global conflict, natural disaster or a disease epidemic, would curb the issue. Despite of these mortality causing events, the population figures are likely to be 5-10 billion by 2100.
Professor Brook also underlined that even the five-year World War III scenario, which killed around same proportion of people in the First and Second World Wars combined, hardly recorded a jinx on the human population trajectory this century.
The study also laid stress on the benefits of effective family planning and education about the reproduction in global perspective.
Researchers said that proper education and awareness hold great potential to control the size of the growing human population over the longer term.
The findings of the research were detailed in the Proceedings of the National Academy of Sciences of the USA.
