Biodiversity encompasses genetic, species, and ecosystem diversity. Biodiversity is dynamic and changes over time, influenced by speciation and extinction events. However, human actions—such as climate change and overexploitation—are increasing extinction rates. As extinction rates increase, ecosystems experience a loss in biodiversity. Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere. We offer quizzes, questions, instructional videos, and articles on a range of academic subjects, including math, biology, chemistry, physics, history, economics, finance, grammar, preschool learning, and more. We provide teachers with tools and data so they can help their students develop the skills, habits, and mindsets for success in school and beyond. Khan Academy has been translated into dozens of languages, and 15 million people around the globe learn on Khan Academy every month. As a 501(c)(3) nonprofit organization, we would love your help!
