Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
The effects of climate change are impacting humans everywhere in the world. [246] Impacts can be observed on all continents and ocean regions, [247] with low-latitude, less developed areas facing the greatest risk. [248] Continued warming has potentially "severe, pervasive and irreversible impacts" for people and ecosystems. [249]
One major component of environmental degradation is the depletion of the resource of fresh water on Earth. [23] Approximately only 2.5% of all of the water on Earth is fresh water , with the rest being salt water . 69% of fresh water is frozen in ice caps located on Antarctica and Greenland , so only 30% of the 2.5% of fresh water is available ...

[17] In 2012 the economic impact of war and violence was estimated to be eleven percent of gross world product (GWP) or 9.46 trillion dollars. [18]
A natural disaster is the negative impact following an actual occurrence of natural hazard in the event that it significantly harms a community. [1] An example of the distinction between a natural hazard and a disaster is that an earthquake is the hazard which caused the 1906 San Francisco earthquake disaster. A natural hazard [18] is a natural ...
Light pollution is the presence of any unwanted, inappropriate, or excessive artificial lighting. [1][2] In a descriptive sense, the term light pollution refers to the effects of any poorly implemented lighting sources, during the day or night. Light pollution can be understood not only as a phenomenon resulting from a specific source or kind ...
