ITAU, the Iranian teacher’s astronomy union, has attempted for many years to introduce astronomy to the teachers and students not only in Iran but also around the world by providing various materials and projects. The primary goal of ITAU is also to protect the environment with a help of students; therefore, first, try to change the attitude of students.

The Australian brushtail possum (Trichosurus vulpecula) is one of many animal species classified as alien under the biosecurity system in New Zealand.

A qualitative, interpretive mode of inquiry was used to analyse data that showed a link between the management of invasive species as a biosecurity risk and young people’s controversial views. An educational program that presents an objective view of invasive species is recommended.
