Causes of Biodiversity Loss a Human Ecological Analysis

Major threats to biodiversity not only emerge from ever-increasing human population but also multiplied by it. Deforestation, land use/cover changes, over-utilization of natural resources, poaching, pollution, etc., are some of the direct outcomes of increasing population leading to erosion or loss of biodiversity.. The rate of change in one aspect of biodiversity, such as loss of species richness, does not necessarily reflect the change in another, such as habitat loss. Moreover, some aspects of biodiversity loss are not easily measured, for instance the fact that the same species are increasingly found at different locations on the planet and that overall biodiversity is decreasing. Biodiversity loss

loss of biodiversity and the prevalence of novel pollutants the approach is useful for informing policy.6’ 7 Recent research has shown that defining boundaries for environmental change at regional scales may be more useful.8 This POSTnote summarises a number of drivers of environmental change and some related national and international trends in atmospheric, aquatic and terrestrial. What are the current trends and drivers of biodiversity loss? Across the range of biodiversity measures, current rates of loss exceed those of the historical past by several orders of magnitude and show no indication of slowing. Biodiversity is declining rapidly due to land use change, climate change, invasive species, overexploitation, and pollu-tion. These result from demographic, economic

Ecosystems and Biodiversity National Climate Assessment

For the purposes of detailed analysis, and the creation of indicators to measure or monitor trends, exactly how biodiversity is defined will influence what is measured 7, 27, 28. Biodiversity indicators aim at using quantitative data to measure aspects of biodiversity, ecosystem condition, services, and drivers of change. This advances understanding of how biodiversity is changing over time. Climate change: for example, heating of the Earth’s surface affects biodiversity because it endangers all the species that adapted to the cold due to the latitude (the ….
