Pollution is the alteration of an entity or environment's normal conditions by chemical or physical agents which make it unsafe or unsuitable for regular use. Pollution is always a negative alteration of the natural state of the environment, normally attributable to human activity. Accordingly, it is considered to be a type of environmental impact.
Some of the most dangerous forms of pollution for the environment and people are:
Pollution due to waste
The effects of pollution on nature are devastating. It affects both people and ecosystems in diverse ways: the hole in the ozone layer, global warming, ocean acidification, acid rain, etc.
With regard to air pollution, greenhouse gas (GHG) emissions caused by people are the main cause of climate change. Most emissions reach the atmosphere as a result of burning coal (43%), followed by burning oil (33%).
If pollution levels continue to rise, it's expected that global GHG emissions will increase by 50%, mainly due to the 70% increase in CO₂ emissions in connection with energy production from non-renewable sources.
As a solution to excessive pollution and with a view to controlling it, there are plans to create a sustainable development economy that reduces the carbon footprint and guarantees natural resources to meet the needs of current generations without compromising the development of future generations.
