For instance, every day students are using social media platforms like Instagram, Twitter and Facebook — but they may not realize that things they post to social media can be seen by potential future employers and could work against them.
In another class, on psychology and a sustainable world, Crabb tries to sensitize students to how their behavior impacts the Earth.
“Obviously, global warming, overpopulation and resource depletion are all issues that are happening right in front of our eyes,” Crabb said. “I think students need to be armed with some basic understanding of what’s happening to the planet, and why people’s thoughts and behaviors are making [detrimental environmental impacts] happen.”
Similarly, Crabb believes that the global economic system is in trouble and that huge shock waves are coming soon.
“I think we’ve reached the limits of growth, and we’re going to see some of that growth fall apart,” Crabb said. “Resources are finite. The planet is finite.”
It’s nice to live in a “consumer dream” where we can buy anything we want online, anytime we want, Crabb said. It seems like a wonderful way of life. And yet, unrestrained consumerism is harming the planet, is not sustainable, and can’t go on forever, Crabb tells his students. “My job is to teach young people, and that’s what I try to do,” he said.
