Taking more water from rivers will accelerate biodiversity loss.
He is right to highlight the "massive and accelerating" biodiversity and ecosystem loss, as well as climate change.
Concerns have been raised that this development might accelerate biodiversity loss due to high crop cover and reduced light availability in energy crop stands, which could further deteriorate the growing conditions for declining arable plant species.
These new technological approaches may accelerate biodiversity inventories, may help in documenting the presence of insect species before they become extinct, and may offer a feasible way to monitor extremely abundant and diverse insect groups.
However, given that perhaps only 5-105-10%animal species are described [ 4, 21] and that rare taxa are commonly encountered in biodiversity research [ 22], approaches that do not rely upon a well-developed taxonomy would be valuable for accelerating biodiversity research, such as flagging individuals that require taxonomic attention, and for performing rapid biodiversity inventories.
To accelerate local biodiversity assessments for conservation and resource management, scientists need both cost-effective survey methods and validated statistical models that link sample data to estimates of true species richness.
The current accelerated erosion of biodiversity is being manifested at three levels, affecting (1) the diversity of our planet's ecosystems and landscapes, (2) the richness of species in most parts of the world, and (3) the genetic diversity of several wild species and most domesticated ones.
Moreover, these achievements have been accomplished at the expense of environmental damages such as biodiversity loss, accelerated soil erosion and degradation, eutrophication including algal blooms and oceanic dead zones, or pesticide effects on humans and wildlife4.
Human interventions may represent obstacles to such fluxes between ecosystems and they may affect landscape evolution and equilibrium conditions in terms of biodiversity reduction, accelerated erosion phenomena, hydrological instability and flood events that are well recognized consequences of anthropic impact.
The results are lethal: some aerial surveys suggest giraffe numbers around the Mara have fallen by 80% since 1979.The hunting debateSome environmental economists contend that the failure of conservationists to take local cost-benefit analysis seriously has accelerated the loss of biodiversity.
