Key Concepts

Species Extinction

Species extinction is the complete loss of a species from Earth, often as a result of various pressures such as environmental changes, habitat loss, and human activities. Understanding species extinction involves examining both natural occurrences and anthropogenic impacts on biodiversity.

Habitat Destruction

Habitat destruction refers to the process by which natural environments are degraded or eliminated, frequently due to human activities such as urbanization, agriculture, deforestation, and industrial development. It is widely recognized as one of the primary causes of species extinction because it removes the necessary resources that species need to survive.

Overexploitation

Overexploitation involves the unsustainable use of natural resources, including the harvest of species at rates faster than they can replenish. This practice is a significant factor in species extinction, as it directly reduces population sizes and disrupts ecosystem balance.

Invasive Species and Exotic Introductions

The introduction of invasive species, such as exotic predators and pathogens, can lead to the displacement, decline, or extinction of native species by preying on them, outcompeting them for resources, or transmitting diseases. This concept is crucial in biodiversity studies as it highlights how alterations in species composition affect ecosystem health.

Climate Change and Sea Level Rise

Climate change encompasses a broad range of phenomena, including temperature increases, altered weather patterns, and rising sea levels. While climate change can indirectly affect species through habitat modification and environmental stress, rising sea levels are generally not considered a primary cause of species extinction on their own compared to more direct drivers like habitat destruction or overexploitation.
