Geography and climate change challenge the viability of sea-level cities in Vietnam, but architects, researchers, and urban planners work together to find creative solutions. One architect in Ho Chi Minh City designed green roofs to absorb the rainwater that causes floods.

Millions of families of arrested individuals do not know what to do to help, how to obtain a lawyer, or what the process entails in the court system.

The Total Sanitation Campaign is starting to change villagers’ minds by having local leadership persuade those who resist the toilets by holding community activities and creating special committees to maintain the sanitation.

Clean water and healthy ecosystems are becoming increasingly difficult to come by. With floating islands and other inventions, eco-entrepreneur Bruce Kania thinks that biomimicry - such as reconstructing wetlands and growing biofilms - can tackle the toughest of water problems.

Civic leaders in the U.S. struggle to effectively help their distressed neighborhoods. East Lake, Atlanta, created a replicable model that mixes residents of differing socio-economic status, and focuses on education and health in the area.

Warming water has led to the collapse of coral reef systems in the western Indian Ocean, essential to fisheries, protecting shorelines, and reducing beach erosion and sea-level rise. Marine scientists from Nature Seychelles, as part of an international project to protect and restore the reefs, are promoting varieties of coral that they have found to be resistant to the rise in temperature.

Global social and economic problems are difficult to change. However, fan-activism fuels the interests of fans of popular young adult fiction.
