Learning from Past Ecosystems and Their Changes
This post will be an introduction to the topic of future ecosystems by going through learning from past ecosystems and their changes for Prelim Biology.
Topic: Future Ecosystems
- Investigate changes in past ecosystems that may inform our approach to the management of future ecosystems, including:
- The role of human-induced selection pressures on the extinction of species
- Models that humans can use to predict future impacts on biodiversity
What Have We Learned?
Following the development of the human species, various other species have suffered. Using Australia as an example, the introduction of cane toads has lead to the reduction of various resources for native species and the hunting of thylacines to extinction. Human-induced selection pressures come from various human activities such as pollution, deforestation, and hunting/poaching.
This video goes through 5 human impacts on the environment.
This video goes through pollution and its effects.
This video goes through a little about climate change which has been largely induced by human activities.
By looking at the past impacts of humans on species, we can strive to reduce them or support endangered species as well as spread awareness so that we can reduce our future impact, support more biodiversity, and subsequently, nature.
