Mohammed Rezwan: Floating schools
Climate change is exacerbating flooding in waterlogged Bangladesh. Already, hundreds of schools get wiped out during the monsoon season. Mohammed Rezwan builds floating schools, healthcare facilities and libraries. "If 20 percent of the land goes under water, which may happen in the next 10 to 20 years, where will these people go? We don't have enough space, enough land. People have to live on the water in some way."
