A city that is big enough to be home for more than 10 million people. The growing areas and growing number of people does affect the way of life in those cities.
Can a city be too big? Is there a limit to which a city can grow, until it cannot sustain itself and function as a city any more?

Megacities may have the benefits of developed infrastructure, increased opportunities and advanced people interactions, but it also means with the increased \population, the problems get bigger as well.
It most definitely means more sustainability and economy challenges.
In the article above, there are evidence of Megacities struggles, that are actually appearing alongside with the increase in population. Air pollution, transport congestion and high house prices are among the challenges discussed
But here is the example of the Megacity fighting its way through global warming and rising sea level:
Jakarta, Indonesia
Suffering from all sorts of environmental problems from deforestation to global warming. The intensity of these issues is so high that the capital could one day become uninhabitable.
Global warming causes extreme floods in the area and scientists are predicting to have more. According to Owen Cooper, who works at the Earth Systems Research Lab in Boulder, Colorado, the sea level in Jakarta rise 6-9 mm per year which is faster compared to the rest of the globe.
In order to fight the floods, the city’s government has decided to build a 32-kilometre seawall and a chain of artificial islands. The project is expected to take 30 years to complete.
