Key Concepts

Overexploitation

Overexploitation refers to the unsustainable harvesting of wildlife and natural resources, including practices like overhunting, overfishing, and excessive logging. This activity can lead to significant declines in species populations and disrupt ecosystem functions, posing a serious threat to biodiversity.

Pollution

Pollution involves the introduction of contaminants into the natural environment that cause adverse changes, affecting air, water, and soil quality. While it can directly or indirectly harm wildlife by altering habitats and reducing resource quality, it is typically one among several factors contributing to the loss of biodiversity.

Invasive Species

Invasive species are non-native organisms that, when introduced to new environments, can outcompete, prey on, or bring diseases to native species. While they can have severe impacts on local biodiversity by disrupting ecosystem balance, their effects are often compounded by other threats like habitat loss.

Habitat Loss

Habitat loss is the process by which natural environments are altered or destroyed, often due to human activities such as deforestation, urbanization, and intensive agriculture. It is widely recognized as the greatest threat to biodiversity because it reduces the living space available for species, leading to declines in populations and the eventual extinction of species.

Biodiversity

Biodiversity refers to the variety of life on Earth, including the diversity of species, ecosystems, and genetic resources. It is crucial for ecosystem stability and the provision of ecosystem services such as clean water, air, and pollination, which are essential for human survival and well-being.
