Pollution is the introduction of contaminants into the natural environment that cause adverse change. [ 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 ...
Airplanes contribute to damaging our environment since airplanes cause greater air pollution as they release carbon dioxide along with nitrogen oxides, which is an atmospheric pollutant. Exhaust emissions lead to changes in the amounts of the greenhouse gases ozone and methane . [ 51 ]
Environmental protection. Environmental protection is the practice of protecting the natural environment by individuals, groups and governments. [ 1] Its objectives are to conserve natural resources and the existing natural environment and, where it is possible, to repair damage and reverse trends. [ 2]
Air pollution is the contamination of air due to the presence of substances called pollutants in the atmosphere that are harmful to the health of humans and other living beings, or cause damage to the climate or to materials. [ 1] It is also the contamination of the indoor or outdoor environment either by chemical, physical, or biological ...
Human activities — for instance, the way we heat our homes, power our air conditioners, fuel our cars and produce our food — all contribute to greenhouse gas emissions, which causes the ...
Ecology portal. v. t. e. Plastic pollution is the accumulation of plastic objects and particles (e.g. plastic bottles, bags and microbeads) in the Earth's environment that adversely affects humans, wildlife and their habitat. [ 1][ 2] Plastics that act as pollutants are categorized by size into micro-, meso-, or macro debris. [ 3] Plastics are ...
In 2018, CO 2 emissions averaged 88 grams of CO 2 per revenue passenger per km. While the aviation industry is more fuel efficient, overall emissions have risen as the volume of air travel has increased. By 2020, aviation emissions were 70% higher than in 2005 and they could grow by 300% by 2050.
Digital ecology. Digital ecology is a science about the interdependence of digital systems and the natural environment. [1] This field of study looks at the methods in which digital technologies are changing the way how people interact with the environment, as well as how these technologies affects the environment itself. It is a branch of ...
