Megacities are non sustainable environment as they require massive infrastructure,transportation and energy and water consumption,generate huge amounts of sewage and air and water pollution.
Now climate change had seen severe weather pattern changes from flooding to wildfires and droughts.Megacities need to consume.huge amounts of electricity and clean water so in a situation of energy crisis,the cost of living escalates.It becomes worse when there is drought and threatens food production so contributes to food insecurity.
More than ever,consumerism driven economic growth has to change to a more sustainable model.
Its vital to get a balance between gdp growth and environmental sustainability.
