Pollution is the introduction of contaminants into the natural environment that cause harm. [1] Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants.
Biological pollution (impacts or bio pollution) is the impact of humanity's actions on the quality of aquatic and terrestrial environment. Specifically, biological pollution is the introduction of non-indigenous and invasive species, [ 1 ] otherwise known as Invasive Alien Species (IAS).
Water pollution also reduces the ecosystem services such as drinking water provided by the water resource. Sources of water pollution are either point sources or non-point sources. [156] Point sources have one identifiable cause, such as a storm drain, a wastewater treatment plant, or an oil spill. Non-point sources are more diffuse.
The fishing gear is made up of non-biodegradable plastic in many different species of coral get tangled in which causes them to lose tissue and possibly die. [160] Plastic pollution has the potential to poison animals, which can then adversely affect human food supplies.
The international pictogram for environmental hazards.. Environmental hazards are hazards that affect biomes or ecosystems. [1] Well known examples include oil spills, water pollution, slash and burn deforestation, air pollution, ground fissures, [2] and build-up of atmospheric carbon dioxide. [3]
Plastic pollution in the ocean is a type of marine pollution by plastics, ranging in size from large original material such as bottles and bags, down to microplastics formed from the fragmentation of plastic material. Marine debris is mainly discarded human rubbish which floats on, or is suspended in the ocean.
Air pollution can cause diseases, allergies, and even death; it can also cause harm to animals and crops and damage the natural environment (for example, climate change, ozone depletion or habitat degradation) or built environment (for example, acid rain). [3] Air pollution can occur naturally or be caused by human activities. [4]
Animal agriculture is a cause of harmful particulate matter pollution in the atmosphere. This type of production chain produces byproducts; endotoxin, hydrogen sulfide , ammonia, and particulate matter (PM), such as dust, [ 61 ] [ 62 ] all of which can negatively impact human respiratory health.
