The Great Barrier Reef's environmental pressures include water quality from runoff, climate change and mass coral bleaching, cyclic outbreaks of the crown-of-thorns starfish, overfishing, and shipping accidents. The government of Queensland currently kills sharks in the Great Barrier Reef using drum lines, causing damage to the marine ecosystem ...
This article is a list of environmental disasters. In this context it is an annotated list of specific events caused by human activity that results in a negative effect on the environment . Main article: Environmental disaster

The term incidents refers to any significant human activity, accidental or not, that contributes or creates the conditions in which environmental and cultural heritage is degraded. Conditions of degradation can be determined if the item or event, without human interaction would have sustained itself markedly better.
An example is zinc oxide, a common paint pigment, which is extremely toxic to aquatic life. [citation needed] Toxicity or other hazards do not imply an environmental hazard, because elimination by sunlight , water or organisms (biological elimination) neutralizes many reactive or poisonous substances. Persistence towards these elimination ...
Environmental degradation is the deterioration of the environment through depletion of resources such as quality of air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable.
Exposure to particulate matter of less than 2.5 micrometers in diameter led to significant changes in ROS levels, indicating that particulate matter exposure was a causative agent of oxidative stress in Tigriopus japonicus. [42] In addition to aquatic invertebrates, negative effects of particulate matter have been noted in mammals as well.
