Before the year is up, the global human population is expected to surpass the 8 billion mark. Along with it will come environmental challenges, but also an opportunity to diversify the global economy.
The United Nations global population projection estimates we will reach a global population of 8 billion people by November of this year, with that number increasing to 10 billion by 2080.
Surpassing the 8 billion mark is indeed a major milestone, but the figure alone is not telling of the fact that population growth is at its slowest rate since the 1950s.
Global fertility rates have been on a steady decline, with two-thirds of all people living in regions where births per woman have fallen below the replacement rate of 2.1. In these areas, government policies are typically driving this rate down.
For this reason, the projected growth will not be evenly distributed across the world. Eastern and Southeastern Asia are expected to see their populations shrink, while North American and European populations will grow at slow rates.
Out of all regions, Sub-Saharan Africa and Central and Southern Asia will see the fastest growth in numbers of people, particularly in the Democratic Republic of Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, and the United Republic of Tanzania.
It’s undeniable that a higher global population risks placing additional strain on the planet, especially when it comes to an increase in demand for natural resources and trying to ensure we don’t destroy ecosystems in that process.
The UN states that though population growth ‘may not be the direct cause of environmental damage, it may nevertheless exacerbate the problem or accelerate the timing of its emergence.’
In particular, the fight against climate change will become more difficult if our reliance on fossil fuels isn’t significantly reduced across the board. Whether larger populations increase their contribution to greenhouse gas emissions will depend on the availability of green technology in certain regions.
The good news is, Sub-Saharan Africa – where populations are rapidly growing – is waking up to its most valuable and abundant source of renewable energy: the sun. In 2021, the Africa Solar Industry Association (AFSIA) identified over 7,600 new solar projects, with more than 1,000 already in operation.
The rest of the world has also recognised the region’s green potential, with Sub-Saharan Africa receiving over $34.7billion in international investment for its renewables sector from 2011 to 2020.
If momentum, planning, and financial backing for harnessing and storing renewables continue as they are, it is entirely possible that the region will become a ‘powerhouse’ for solar as predicted – subsequently supporting its growing population in a way that is not taxing on the environment.
Opportunity sparked from growth
Aside from needing to deal with the challenge of adequately distributing natural resources, many nations have real potential to reap the rewards of a growing local population.
Reports by The World Bank suggest that – with the right policies and actions put in place – the likelihood of capturing the social and economic benefits of population growth will increase accordingly.
No doubt, the emergence of a large young, working population in Sub-Saharan Africa is sure to give the region a major economic boost, but experts say this will can only be fully realised if more focus is placed on empowering women and girls.
By investing in women and girls’ education, skills, and providing them with equal market, social and decision-making powers as their male counterparts, African nations will get the most out of their ‘demographic dividend’.
It’s clear that there will be obstacles that need problem solving through strong social policies, increased economic funding, and clear planning for improved infrastructure in regions where populations are growing.
On the other hand, it’s encouraging to see that projects are already underway to support rising populations, and when prosperity of nations relies on equal opportunities, it’s likely improvements to health and social policies are sure to follow.

A new report reveals millions of mums and children face quietly pervasive economic coercion – with family budgets being used as tools for domestic abuse.
Abuse isn’t always obvious – least not when it takes place in the domestic sphere. But new figures from the charity Surviving Economic Abuse (SEA) show that financial coercion is quietly affecting a staggering number of women and children. It’s a form of violence that remains underreported...
Lack of research and misdiagnosis is forcing couples, disproportionately women, into gruelling fertility treatment.
When a couple struggles to conceive, you would expect both partners to be treated equally during the process of diagnosis. But fertility care still leans heavily toward invasive focus on the woman and little attention on the man.
Not only does this imbalance place the onus of fertility struggles onto women, who then face an isolating sense...
On November 4, 2025, 34-year-old Zohran Mamdani was elected as the first Muslim mayor in New York City. And this is largely due to the influence of Gen Z.
After four long years of subpar mayoral leadership, New Yorkers, especially Gen Z, are ready for a change.
As of November 4, 2025, Zohran Mamdani is the change New York so desperately needed. The significance of the 34-year-old's mayoral win extends beyond...
On the International Day for the Elimination of Violence Against Women, UN Women reveal a disturbing rise in violent abuse toward women in digital spaces – with little consequence for perpetrators.
A few years ago, someone described the internet to me as ‘the world’s biggest public square,’ which sounded charming until I remembered that public squares throughout history have also hosted witch trials, duels, riots, and the occasional beheading.
The past year...
