Environmental degradation is the deterioration of the environment through depletion of resources such as quality of air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable.
Environmental concerns can be defined as the negative effects of any human activity on the environment. The biological as well as the physical features of the environment are included. Some of the primary environmental challenges that are causing great worry are air pollution, water pollution, natural environment pollution, rubbish pollution, and so on.
Environmental degradation is one of the ten threats officially cautioned by the High-level Panel on Threats, Challenges and Change of the United Nations. The United Nations International Strategy for Disaster Reduction defines environmental degradation as "the reduction of the capacity of the environment to meet social and ecological objectives, and needs". Environmental degradation comes in many types. When natural habitats are destroyed or natural resources are depleted, the environment is degraded. Efforts to counteract this problem include environmental protection and environmental resources management. Mismanagement that leads to degradation can also lead to environmental conflict where communities organize in opposition to the forces that mismanaged the environment.
Biodiversity lossDefaunation and Holocene extinction
Scientists assert that human activity has pushed the earth into a sixth mass extinction event. 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. A 2020 report by the World Wildlife Fund found that human activity – specifically overconsumption, population growth and intensive farming – has destroyed 68% of vertebrate wildlife since 1970.

Ecotoxicology aims to understand the impact of chemicals and other stressors on organisms in the environment with a particular focus on population-, community- and ecosystem effects. Based on a mechan
La fabrication, l'utilisation et le rejet des objets ont des effets considérables sur l'environnement. Les matériaux utilisés pour les fabriquer peuvent provenir de sources non renouvelables, telles que le pétrole, le gaz naturel ou les métaux rares, ce qui peut entraîner l'épuisement des ressources naturelles. La production d'objets peut également générer des émissions de gaz à effet de serre, contribuant au changement climatique.
La surconsommation désigne un niveau de consommation situé au-dessus de celui des besoins normaux ou d'une consommation moyenne. Au-delà d'un certain seuil, la surconsommation est un facteur de surexploitation de ressources naturelles, pas, peu, difficilement, dangereusement ou lentement renouvelables. Quand une de ces ressources épuisées ne peut plus être remplacée par une autre, des besoins primaires peuvent ne plus pouvoir être assurés.
L'agriculture itinérante est une forme d'agriculture essentiellement basée sur l'autoconsommation, et caractérisée par le défrichement, la mise en culture puis l'abandon (retour à la friche) d'une parcelle dont la fertilité a beaucoup diminué au profit de la culture d'un autre terrain plus fertile. Les familles, groupes ou tribus voyagent alors de terrain en terrain, en laissant en quelque sorte le sol en jachère longue durée. Quelques décennies ou siècles plus tard, il peut à nouveau être mis en culture. .
