About
The recent biodiversity assessments conducted by WWF and other contributing organizations revealed a 60% decline in populations of fish, birds, mammals, amphibians, and reptile species in the past 40 years. More than 1 million species are now threatened with extinction, and that number will only increase if we don’t change course now. In this activity, students will plot species population data and use observed trends to determine the probability of those species’ survival.
Key objectives for students
Graph population data of endangered species over time.
Analyze and interpret population trends to predict extinction probability.
Explain why monitoring these population trends is important in shaping our actions for the future.
