According to the UN population division, there are currently 7,713,468,000 on our planet Earth. And those figures are expected to grow fast to 8.5 billion by 2030, and at the end of the century we would be almost 11 billion.
Not we though, most of us would have passed on by then. How habitable would the world be for 'them', future generations?
Food production would be critical in the survival of our species, and climate change, land degradation, loss of fertility, loss of lands and gradually shift from agriculture doesn't help our chances.
Most of population growth would be happening in developing countries, such as mine Nigeria.
Couple of decades back, agriculture was the main source of livelihood, and each family produced what they consumed, then colonization happened, and brought with it Western Civilization. Now this opened multiple opportunities in industry, and with the discovery of oil, and other minerals, farming moved to the background, now it's the responsibility of a few to feed the whole. This scenario played out in many countries. We all have to take up this responsibility to produce food or at least help sustain the fertility of the earth, especially the oceans.
Internally displaced persons, refugees, and immigrants are also on the rise. Results of war, riots, natural disasters and lack of opportunities due to corruption in many countries. This puts pressure on available land for food and shelter.
One of the upsides of population growth is increase in labour force. If we put our hands together; there maybe a chance.
I believe the deciding factor would be the people in power. We NEED to get them to act.
