Population growth is not “out of control”, this gets stated all the time but is wrong if you look at the data. Population growth already HAS been slowed. It’s been slowed for over 30 years.
Population growth has fallen every year since 1987, where it was 1.8%. The number of children in the world as a total has stopped increasing. It’s now at a long flat peak and it will go down again.
The population will peak at around 11 billion by 2100 before decreasing again. Some balk at this figure, but we’ll already be at 8 billion in 3 years. That’s a growth of 3 billion over the next 75 years, compared to growth of 5 billion from the last 75 years. This is the UN’s estimate, some estimate lower.
The population problem will, and already is solving itself, the problem the world faces is that the population growth will continue in places like Africa, where countries are rapidly developing. Asia and Africa already dwarf Europe and North America in terms of population, something that will continue to increase. The problem is those populations use a fraction of the energy on a per capita basis than western countries, but as they continue to develop, their energy usage will increase and the world will not be able to cope.
The problem is they want a life like ours, and who are we to deny it to them? That’s why if we’re serious about this the West needs to take the lead and cut a path forward for developing countries to follow, allowing them to continue to develop but in a more sustainable way than we have. China is a different beast but if we can find a way to make it not only economically viable, but economically beneficial to be sustainable, we could win them over too.
I’m not an environmental expert so whilst I can identify the problem and see where the answer lies, I’m not sure I know what the exact answer is. Part of me thinks it will need a fundamental rethink of how our economy works, to ensure that sustainable practices are rewarded, on every level, individual, company, national and international.
