PTE Summarize Written Text Exercise 21
Global Biodiversity Crisis
The world is facing a major biodiversity crisis, with species extinction rates accelerating due to human activities such as deforestation, pollution, and climate change. Ecosystems rely on biodiversity to maintain balance and resilience, but when species disappear, the entire system can collapse. Scientists estimate that one million species are at risk of extinction, many within decades. This loss threatens food security, clean water, and natural medicine sources. Conservation strategies include creating protected areas, restoring habitats, and reducing carbon emissions. International agreements like the Convention on Biological Diversity aim to coordinate global action, but enforcement and funding remain challenges. Experts warn that preserving biodiversity is not only an environmental issue, but also an urgent economic, social, and ethical imperative.
