Environmental pressure can remain lower even after density increases if what happens?

Correct answer: Resource efficiency, waste management and green planning are strong

Answer: A, when resource efficiency, waste management and green planning are strong. A larger concentration of people can increase demand for water, energy, land and transport, but the environmental effect also depends on how resources and waste are managed. Efficient appliances and systems can reduce resource use; recycling, treatment and safe disposal can reduce pollution; and green planning can protect open spaces, improve drainage and support cleaner settlements. A is correct because these measures can reduce pressure per person and improve the ability of an area to handle density. B is wrong because stopping waste management increases pollution and health risks. C is wrong because destroying water sources damages environmental security. D is wrong because removing green spaces generally reduces ecological protection. High density is not automatically sustainable or unsustainable; planning and management matter. Memory cue: people create pressure, but efficient systems influence the size of the impact.
