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 ...
Triple Planetary Crisis is a term and framework adopted by the United Nations system to describe the three intersecting global environmental crises of pollution, climate crisis, biodiversity loss and/or ecological crises. [ 1][ 2][ 3] This term underscores the interdependence of these issues and their collective impact on the planet's ...
The two atmospheric problems have achieved significantly different levels of understanding by the public, including both the basic science and policy issues. [16] People have limited scientific knowledge about global warming and tend to confuse it with [ 21 ] or see it as a subset of the ozone hole. [ 22 ]
Water pollution is an environmental issue that affects many water bodies. This photograph shows foam on the New River as it enters the United States from Mexico. Environmental issues are disruptions in the usual function of ecosystems. [1] Further, these issues can be caused by humans (human impact on the environment) [2] or they can be natural ...
Main sources of global methane emissions (2008-2017) according to the Global Carbon Project [ 40] Methane emissions come from livestock, manure, rice cultivation, landfills, wastewater, and coal mining, as well as oil and gas extraction. [ 41] Nitrous oxide emissions largely come from the microbial decomposition of fertiliser.
Pollution of the Ganges. The ongoing pollution of the Ganges, the largest river in the Indian subcontinent, poses a significant threat to human health and the environment. [ 1] The river provides water to about 40% of India's population across 11 states. [ 2]
exert a considerable impact on global warming, because it is a key air pollutant and greenhouse gas, and; impact the production of surface level ozone (contributing again to climate change). As a result, photochemical smog pollution at the earth's surface, as well as stratospheric ozone depletion, have received a lot of attention in recent years.
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 ...
