There are five major ways that business activity can threaten ecosystems: climate change, pollution, habitat destruction, overexploitation, and introduction of invasive species.
How is ecosystem disturbed mention four causes?
Important direct drivers include habitat change, climate change, invasive species, overexploitation, and pollution. Most of the direct drivers of degradation in ecosystems and biodiversity currently remain constant or are growing in intensity in most ecosystems (see Figure 4.3).
What are the three ways in which human activity can disrupt ecological balance?
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation.

Common human activities that can harm biodiversity include destruction of natural vegetation for agricultural and urban development, overexploitation of natural resources and the introduction of invasive species.
What are examples of ecological disturbances?
Examples of ecological disturbances include fires, landslides, flooding, windstorms and insect and pest outbreaks. Disturbances often come in the form of short-term or temporary changes to the landscape but can have very significant ecosystem impacts.
What are the causes of ecological disturbance?
Disturbance can result from natural causes or from the activities of humans. Disturbance can be caused by physical stressors such as volcanic eruptions, hurricanes, tornadoes, earthquakes, and over geological time, glacial advance, and retreat.
How do ecological disruptions affect the environment?
Ecosystems change over time. Sudden disruptions such as volcanoes, floods, or fires can affect which species will thrive in an environment. … As species become extinct, the variety of species in the biosphere decreases, which decreases biodiversity, or the variety of life.
