Which five major drivers cause biodiversity loss?

Ecologists have identified five major drivers of biodiversity loss, all of which are significantly influenced by human population growth and the consumption of natural resources. These drivers are:1

• Habitat loss and degradation: This involves the thinning, fragmentation, or destruction of natural environments, which eliminates essential food resources and living space for species. It is considered a primary driver of global biodiversity decline.12
• Invasive species: These are non-native organisms that disrupt ecosystems by outcompeting native species for resources or acting as predators, often leading to population declines or localized extinctions.13
• Overexploitation: This refers to the harvesting of animals, fish, or other organisms at rates that exceed their ability to reproduce and recover, which can deplete populations and trigger trophic cascades.14
• Pollution: The introduction of substances or energy into the environment faster than they can be diluted or decomposed creates health risks, reproductive issues, and mortality in exposed organisms.15
• Climate change: Driven by the burning of fossil fuels, this modification of Earth's climate alters temperature and precipitation patterns, forcing species to adapt to conditions that may exceed their tolerance limits.1
