Beautiful digital art you could display in your classroom to facilitate discussion about global warming. You could present one of images and ask the students what they think it's trying to convey, no text is needed to spark discussion. Great way to get students interested and engaged in the topic.

This photo demonstrates how our world is being destroyed. Our generation oblivious to the impact that they pollute the earth. The government in America is so concerned with the growth of the economy no one takes charge to change our ecological footprint on the world. Additionally, technological advances are always thinking with the idea of "bigger, better." Which as a result does not slow down our ecological footprint.
