Dear MEL Topic Readers,
World ‘faces 80% calorie increase by end of century’
Half a century ago, there were about 3.7 billion humans walking on the planet. The population doubled by 2016 and today, there are about 7.8 billion people living in the world. As the average fertility rate keeps rising from today’s 2.47 to 2.95 in the next three decades, two billion more people will be eating everyday meals in 2050. That’s a 25% increase from now. Though the rate of increase is expected to slow down, one billion more stomachs will be added by the end of the century, bringing the total population to 11 billion. The majority of the increase will come from Africa, whose population is expected to grow from today’s 1.3 billion to 4.3 billion in 2100. Furthermore, as people become taller and heavier, their stomachs become larger and more demanding, meaning they need higher calories to survive. Recently, some researchers estimated that around 250 more calories are needed in one’s daily diet in the future.
Will the world be able to feed that many more stomachs if the size of cultivable land doesn’t expand accordingly? Will agricultural productivity improve more than the rate of population increase? Will people have no choice but to depend on junk food only to fill their stomachs in Africa? What if global warming deteriorates food production?
Enjoy reading the article and think about how humans, their cattle and birds, and fish will survive to the next century.
