As the world's population nears 7 billion the UN has pointed out the future challenges faced by the planet. Even though its highlights the successes of falling fertility rates and rising life expectancy it also states that the population could reach 10 billion by the end of the century causing massive problems.

It also says we should be finding new ways for caring for the ageing population in many countries.
