become gradually smaller in number
Activity 4 Watch the rest part of the video for the solutions
1. Is removing all the obstacles a good idea Why

No. 1. We aren’t likely to give up infrastructure (roads, power or pipelines) anytime soon.
2. Even when we remove physical barriers, mental barriers remain (their stopping power can stick around).
overpass bridges
underpass bridges
Viewing strategies：
active listening
visual observation
note-taking
guide animals over, under or around the obstacles
accommodate various sizes of animals
Activity 5 Watch another video and discuss for further exploration
1. Why are wildlife bridges called “crazy” bridges for animals
2. What are the benefits of building wildlife bridges
Work in pairs and discuss:

increase their chances of survival
2. What are the benefits of building wildlife bridges
Activity 6 Make a presentation for advocating animal bridges
