Next, students will create the ecosystem by placing items such as houses, trees, and grass on the bank of the river. But how well any survivors would fare is a great mystery, one which my colleagues and I took on in a recent research paper Long-Term Trajectories of Human Civilisation.

The events all took place in 2011. Throughout this Spark, students investigate the end of the Cretaceous Period, diving into what happened and how we know it by studying rock strata and geologic time, the rock cycle, and force and motion. Fortunately, no life is believed to have existed at this time. But for the sake of discussion, lets consider the worst-case nuclear war. Even what might appear to be nothing more than a minor change to the global climate can have the effect of irrevocably transforming the ecosystem. In addition to the billions of dollars in property loss and the deep personal loss that many people endure, there are often unseen environmental impacts that have to be mitigated.As we witnessed this fall, hurricanes can be among the most devastating . Coral reef ecosystems - National Oceanic and Atmospheric Administration This event was driven by the rise of cyanobacteria, which were the first organisms to use water for photosynthesis. The Impact of Climate Change on Natural Disasters : Climate change may not be responsible for the recent skyrocketing cost of natural disasters, but it is very likely that it will impact future catastrophes.
