Loss of Louisiana Wetlands due to Mississippi River levees, saltwater intrusion through manmade channels, timber harvesting, subsidence, and hurricane damage. Mercury contamination in Grassy Narrows pollution of Wabigoon River; Oder environmental disaster in 2022; Red Hill water crisis in Hawaiʻi, United States beginning in November 2021
The regime shift in the northern Benguela upwelling ecosystem is considered an example of ecosystem collapse in open marine environments. [24] Prior to the 1970s sardines were the dominant vertebrate consumers, but overfishing and two adverse climatic events ( Benguela Niño in 1974 and 1984) lead to an impoverished ecosystem state with high ...
These can reduce damage and erosion while simultaneously providing ecosystem services such as food production, nutrient and sediment removal, and water quality improvement to society [59] Example of human caused habitat destruction likely capable of reversing if further disturbance is halted. Uganda.
The letter mentions severe damage to the atmosphere, oceans, ecosystems, soil productivity, and more. It said that if humanity wants to prevent the damage, steps need to be taken: better use of resources, abandonment of fossil fuels, stabilization of human population, elimination of poverty and more.

Logging, dredging, conversion of land to ranching or agriculture, mowing, and mining are examples of anthropogenic disturbance.Human activities have introduced disturbances into ecosystems worldwide on a large scale, resulting in widespread range expansion and rapid evolution of disturbance-adapted species.

The decrease can be temporary or permanent. It is temporary if the damage that led to the loss is reversible in time, for example through ecological restoration. If this is not possible, then the decrease is permanent. The cause of most of the biodiversity loss is, generally speaking, human activities that push the planetary boundaries too far.
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. These issues are considered serious when the ecosystem cannot recover in the present situation, and catastrophic if the ecosystem is projected to certainly ...
