The world must not engage in “population alarmism” as the number of people living on Earth nears 8 billion, a senior UN official has said, The Guardian reported. The global population is projected to reach that milestone on 15 November, with some commentators expressing worries about the impact of the growing number on a world already struggling with huge inequality, the climate crisis, and conflict-fuelled displacement and migration. However, Dr Natalia Kanem, executive director of the UN Population Fund(UNFPA), urged countries not to panic but instead focus on helping the women, children and marginalised people who were most vulnerable to demographic change.

“I realise this moment might not be celebrated by all. Some express concernsthat our world is overpopulated, with far too many people and insufficient resources to sustain their lives. I am here to say clearly that the sheer number of human lives is not a cause for fear,” she said.

Kanem said that if governments focused on the numbers alone they ran the risk of imposing population controls that had been shown by history to be “ineffective and even dangerous”. “From forced sterilisation campaigns to restrictions on family planning and contraception, we are still reckoning with the lasting impact of policies intended to reverse, or in some cases to accelerate, population growth,” she said. “And we cannot repeat the egregious violations of human rights … that rob women of their ability to decide whether [or] when to become pregnant, if at all. Population alarmism: it distracts us from what we should be focused on.” As a result of falling birthrates, the pace of worldwide population growth, which reached a recorded peak at just over 2% a year in the late 1960s, has now fallen below 1%. However, the global picture is more varied than ever before. The UN estimates that about 60% of people live in countries with fertility levels below the recognised replacement level (when a population exactly replaces itself from one generation to the next) of an average of 2.1 births for every woman, according to The Guardian. At the other end of the spectrum, just eight countries, including Nigeria, Ethiopia and the Philippines, are forecast to account for half of all population growth by 2050. One of those countries, India, is expected to pass China from next year and become the world’s most populous country.
