In 100 years, Singapore grew from a small colonial port into one of the world’s most well-developed and modern cities. But, what did this transformation cost? Although we claim to be a “garden” city, many of our original forests, wetlands and mangroves have already been destroyed. A few weeks ago, I visited the Keppel Discovery Wetland in Singapore Botanical Garden (SBG), the last refuge for Singapore’s endangered freshwater wetland species. The field trip was part of NUS GE4224 Applied Biogeography module.
