Teaching About Invasive Species is designed as a tool kit. Whether working inside or outside schools, youth educators will find in Green Teacher’s new book the innovative perspectives, program ideas, games and activities that they need to engage young people from 6-19 years of age in this challenging topic. Invasive species, if unchecked, will continue to have significant negative impacts on our environment and on our economy. Fortunately, the spread of many invasives can be checked.
