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 ...
Environmental disasters show how the impact of humans' alteration of the land has led to widespread and/or long-lasting consequences. [3] These disasters have included deaths of wildlife, humans and plants, or severe disruption of human life or health, possibly requiring migration. [4]
The environmental impact of irrigation includes the changes in quantity and quality of soil and water as a result of irrigation and the ensuing effects on natural and social conditions at the tail-end and downstream of the irrigation scheme. The impacts stem from the changed hydrological conditions owing to the installation and operation of the ...
[4] [5] [6] A disaster happens when a natural or human-made hazard impacts a vulnerable community. It results from the combination of the hazard and the exposure of a vulnerable society. Nowadays it is hard to distinguish between natural and human-made disasters. [3] [7] [8] The term natural disaster was already challenged in 1976. [6]
Flood modelling is a tool used to model flood hazard and the effects on humans and the physical environment. [65] Flood modelling takes into consideration how flood hazards, external and internal processes and factors, and the main drivers of floods interact with each other.
[5] [6] The loss of biodiversity has been attributed in particular to human overpopulation, continued human population growth and overconsumption of natural resources by the world's wealthy. [ 7 ] [ 8 ] A 2020 report by the World Wildlife Fund found that human activity – specifically overconsumption, population growth and intensive farming ...
Beyond physical risks, floods have severe long-lasting mental health consequences, including post-traumatic stress disorder (PTSD). [8] Climate change also facilitates the spread of diseases like Lyme disease and leptospirosis through warming temperatures and habitat changes that bring humans into closer contact with disease-carrying organisms. [9]
The environmental impact of reservoirs comes under ever-increasing scrutiny as the global demand for water and energy increases and the number and size of reservoirs increases. Dams and reservoirs can be used to supply drinking water , generate hydroelectric power , increase the water supply for irrigation , provide recreational opportunities ...
