When the first World Population Day was marked in 1990, the global population stood at a little over five billion.
It’s now over half that again, measuring 7.6 billion.
Each day, 1 billion people have no access to food and water. Also, many people in the developing countries are becoming illiterate. Most of them get their children married at young age which increases the chances of giving birth to more kids.
Do we have enough room for everyone?
