Regarding the anthropocene(The time period where humans have greatly changed the course of earth and its geography/ecosystems), I believe an interesting topic is how the anthropocene and the great acceleration have affected marine ecosystems. We can see signals of this type of change in coral reefs today as many corals are undergoing a process known as bleaching, where the corals expel the algae that gives them color due to harmful changes in temperature. Corals are the foundation of life in coral reefs, so unhealthy corals has an impact on the rest of the ecosystem.
