An important implication is that the degradation of one element of the ecosystem or the disappearance of one species could modify the whole ecosystem and subsequently damage other components (or species) as well.
The shrinking of the lake has diminished a fragile ecosystem, with the gradual disappearance of native wildlife including the brine shrimp Artemia and migratory birds like flamingos and pelicans.
The way to cost nonmarket goods—such as damage to or disappearance of ecosystem services, and loss of species or human lives has not yet been agreed upon.
Less than a month ago we were treated to an authoritative interagency report, which Mr. Bush belittled, that reinforced earlier warnings from mainstream scientists that unchecked warming will bring devastating consequences, including rising seas, coastal flooding, disruption of snow-fed water supplies, heat waves and the disappearance of sensitive ecosystems like coral reefs.
Fossil fuel consumption has now joined the traditional drivers of disaster risk such as poverty, inappropriate land use, weak building codes, the disappearance of protective ecosystems and lax governance, as drivers of preventable loss of life, displacement and loss of livelihoods.
In the opinion of representatives from both regions, the highest ThRI values concern transformation of aquatic meadow ecosystems, land use changes, and disappearance of typical elements of cultural heritage, particularly traditional forms of rural architecture (Fig. 6, values 5, 6, or 7).
But these barriers take a toll on the environment; France's La Rance barrage, opened in 1966, has caused progressive silting of the area's ecosystem and has contributed to the disappearance of species such as sand eels and plaice.
Since the dams beavers build create and regulate wetlands, their disappearance further transfigured the ecosystem.
Their scarcity and/or disappearance in conventional agro-ecosystems have led them to be considered as necessary for the restoration of the agro-environment.
It is even more difficult, but equally unpleasant, to imagine how their disappearance might change an entire ecosystem.
