Final answer:
Politically active citizens and organizations are most likely to lead the fight against developments that displace residents, forming coalitions with other groups affected by urban development and extractive industries. Successful gentrification can be achieved without displacing local residents and may improve the economic standing of long-term residents.
Step-by-step explanation:
The fight against developments that displace residents is most likely to be led by politically active citizens and organizations that advocate for the rights of ordinary people. In the context of gentrification and urban development, these groups often form coalitions with farmers, urban activists, and local peoples affected by extractive industries to push for environmental reform, accountability, and fair treatment. They may also protest against pro-growth policies, demand smarter development, and challenge anti-immigration legislation. It is important to note that successful gentrification can be achieved without significant displacement of local residents, and may even improve the economic standing of long-term residents in gentrifying areas.
