The Triple Threat: How Human Activity Reshapes Global Biodiversity
In short: This video breaks down the primary drivers of biodiversity loss for the 2027/28 A-Level Biology exams. It explores the interconnected pressures of population growth, industrial farming, and climate change on the natural world.
The content examines three specific human-driven pressures. Population growth leads to habitat destruction through urban sprawl and increased demand for housing and agriculture. Farming practices further impact ecosystems by creating monocultures and introducing chemicals like herbicides, pesticides, and fertilizers, while overgrazing strips away plant diversity.
The video also addresses the consequences of climate change, specifically how melting ice caps and rising sea levels destroy polar and coastal habitats. It highlights the broader ecological shift of tropical diseases spreading into new regions. To mitigate these impacts, the video discusses balancing agriculture with biodiversity through methods like crop rotation and maintaining hedgerows.
