The decision to have a child is primarily an emotional one and often in India, a cultural pressure to which most people succumb. But as resources are being stretched to breaking point, it is evident that the uncomfortable truth associated with overpopulation is crossing people’s minds and motivating some to not contribute further to the problems. A study published in Environmental Research Letters equates the impact of having one fewer child to reducing 58 metric tonnes of CO2 for each year of the parent’s life. Other helpful ways to reduce one’s carbon footprint pale in comparison. Going car-free saves emissions by 2.4 metric tonnes and eating a plant-based diet 0.82 metric tonnes.
Overpopulation is usually defined as the state of having more people in one place that can live there comfortably, or more than the resources available can cater for. By that measure, Dhaka is a textbook example.
If we managed urbanisation properly, we could nearly remove ourselves from a considerable percentage of the the planet’s surface. That would be good for many of the threatened species we share this planet with, which in turn would be good for us, because we are completely enmeshed in Earth’s web of life.
Rather than being more violent, people from non-states are more vulnerable to lethal warfare compared to inhabitants of states.
Fertile soil is being lost at rate of 24bn tonnes a year through intensive farming as demand for food increases. Heavy tilling, multiple harvests and abundant use of agrochemicals have increased yields at the expense of long-term sustainability. Industrial agriculture is good at feeding populations but it is not sustainable. It’s like an extractive industry.
India’s population of 1.3bn is still growing, and as it does it is increasingly encroaching into the country’s traditional wild spaces and animal sanctuaries, where people compete with wildlife for food and other resources.
In 2050, when the population of Africa is two and a half times larger than now, the continent will scarcely be able to grow enough food for its own population
With rail routes plagued by overcrowding and delays, London’s dependence on workers willing to travel many hours to the capital every day is coming under severe scrutiny. The population of London is expected to reach 10 million by 2030, with a substantial growth in numbers – from 15 million to 17 million – expected across the wider south-east region over the same period.
