But for the sake of discussion, lets consider the worst-case nuclear war. Stradbroke Island, as are the abiotic factors of nitrogen and fire. Regardless of what all the catastrophe entails, it raises the question of what happens next. The effects of the nuclear war could precipitate additional catastrophes, such as a pandemic (due to weakened public health infrastructure) or a catastrophic failure of geoengineering (leading to accelerated climate change). As long as people will be buying things, trees will be cut down. What are the positive human impacts on ecosystems?

Evidence even goes so far as to suggest that the coastal erosion that accompanied the event deposited a great deal of phosphorous into the ocean, a crucial element for all life on Earth. However, the hypothesis remains controversial, and while it is clear that major glaciations did indeed occur, their extent remains largely unknown. The hypothesis claims that, some 4.5 billion years ago, there was a catastrophic impact event between the young Earth and another planet-sized object. In turn, this drives climate change.
