Effects of Drilling and Fishing on the Ecosystem

These pictures will show to students that humans do have an effect on the ecosystem. The students will have a visual representation of how harvesting tuna, and oil drilling can disrupt ecosystems across the globe. In viewing these pictures, the students will understand that these organisms can not reproduce, and therefore disrupt the other levels of the ecosystem they are part of. Students will now be able to describe why humans are now an integral part of the food chain, and their impact on ecosystems as a whole.
