Genetic Diversity and Agriculture

The video discusses the decline in crop diversity due to industrialization and monoculture farming. It highlights the historical variety of seeds and the impact of the 1971 corn crisis, which was mitigated by the genetic diversity found in Teosinte. The video emphasizes the importance of preserving genetic diversity through seed banks to combat future challenges posed by climate change and population growth.
