With a population of nearly 40 million people, California is the nation’s most populous state. As the largest city in California, and the second largest in the United States, Los Angeles, continues to grow in population. Due to continuous growth, cities like Los Angeles are using up more natural resources and becoming more congested and polluted than ever before. As these cities grow, they are being forced to expand. Along with expansion comes the demolition of natural habitats. BiodiverCity is an opportunity for a structure that needs no outside sourcing of energy and that can completely sustain itself, all the while returning nature to its original home within the “concrete jungle” that is downtown Los Angeles, California.
