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 .
What would a social problem of a megacity be?
Lack of hospitalisation, schooling, housing, jobs being taken up, too many people for the amount of public transport.
What are slums a result of which problem? (and why)
Economic issues because a slum is an area of temporary houses often made of corrugated iron, these people end up living in the slums because of a lack of money and they can’t pay for a house.
What is a social challenge of urbanisation and a social opportunity of urbanisation?
A social challenge of urbanisation is that now there are more people the prisons might be more full and also the emergency services would be increasingly busy and there might be over used public transport. An opportunity would be more people to work for the government.
What is a economic challenge of urbanisation and an economic opportunity of urbanisation?
An opportunity of urbanisation (economic) is that there would be more people to do jobs and there wouldn’t be a shortage of people working. A challenge of urbanisation would be inflation of prices eg food and housing and as there would be more people the government might have to pay for more houses to be built but also council flats.
What is a environmental challenge of urbanisation and an environmental opportunity of urbanisation?
Increased air pollution as there are more cars. Also more plastic as more people are dying things made out but also packaged in plastic. An opportunity is that people will live in flats unlike in the rural areas and by living in a flat it is taking up less space so is overall better for the environment.
What are 5 example of megacities.
São Paulo, Shanghai, Mumbai, Cairo, Tokyo
What is an example of something governments around the world are doing to prevent increased population.
