Factors influencing changing ecosystems including climate change and human exploitation
Ecosystems change when climate shifts or humans disturb them. Rising temperatures, deforestation, and overgrazing can all push an ecosystem away from its natural stable state.
Real World
The Great Barrier Reef has experienced five mass bleaching events since 1998, driven by rising sea surface temperatures linked to climate change, with 2016 and 2017 causing the most widespread coral death on record.
Exam Focus
