Sustainability meaning
Sustainability is the idea that humans must interact with the environment in a way that ensures there will be enough resources left for future generations.
Is the population growth sustainable?
No, because as the number of humans increase that increase the food, energy and housing demand also most people have a car which is realising fumes every time it is used so air pollution will go up. Also more people will want food eg meat, this means that more forests will be cut down to accommodate more cows, sheep, pigs etc so there are lees trees which means less oxygen and natural habitat for animals .

Lack of hospitalisation, schooling, housing, jobs being taken up, too many people for the amount of public transport.
