Pollution and Environmental Change.
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).
Natural disturbances include fires, insect outbreaks, disease epidemics, droughts, floods, hurricanes, windstorms, landslides, avalanches, and volcanic eruptions. In terms of frequency and area affected, the two major natural disturbances affecting wilderness areas are fire and insect outbreaks.
Ecosystems are destroyed by such activities as land clearing, urbanization, coastal erosion, and mining.
ecological instability: the process of irreversible change of an. ecological system and the absence of a capability for restoring. its original state after a change. Examples include the ecological succession on glacial.

Once the land is scarred by mining efforts it is left vulnerable to massive erosion. Other events and issues such as natural disasters, war, the construction of dams, and poverty in developing countries also contribute to the destruction of tropical rainforests.
In particular, the term unstable should be restricted to describe an ecosystem which does not represent a certain climax situation. Vulnerable seems to be the right term to characterise those ecosystems which are at greater risk than others of being negatively affected by external impact.
Ecosystems are also affected by human disturbances, which are caused by people. Chemical pollution and urbanization are examples of human disturbances that force change upon an ecosystem. Other examples include deforestation, mining, and light or noise pollution.
Humans have a bigger influence on their physical environment in several ways – they disrupt in ways such as pollution, overpopulation, deforestation, burning fossil fuels etc. such changes have propelled soil erosion, climate change, degraded quality of air and unfit water for consumption to name a few.
Threats to biodiversity include habitat loss, the introduction of alien species, overexploitation, and breaking the connectivity among ecosystems. • Deforestation and draining wetlands can result in habitat loss. • Extinction is a natural event that has occurred throughout Earth's history.
