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 ...
Ecological restoration, or ecosystem restoration, is the process of assisting the recovery of an ecosystem that has been degraded, damaged, destroyed [1] or transformed. [2] It is distinct from conservation in that it attempts to retroactively repair already damaged ecosystems rather than take preventative measures.

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.
An example includes, varying aquatic insects are able to identify appropriate ponds to lay their eggs with the aid of polarized light to guide them, however, due to ecosystem modifications caused by humans they are led onto artificial structures which emit artificial light which are induced by dry asphalt dry roads for an example.

The use of biological remediation has also been implemented in areas of the delta to detoxify and restore ecosystems damaged by oil spills. Bioremediation involves biological components in the remediation or clean-up of a specific site. A study conducted in Ogbogu located in one of the largest oil producing regions of Nigeria has utilised two ...
