We are also putting enormous pressure on populations of wild species, both by bushmeat hunting in the developing world and by large-scale industrial fishing in our seas.

It is these considerations that pose a challenge and difficult to fully.

Biodiversity is not evenly distributed, rather it varies greatly across the globe as well as within regions. Among other factors, the diversity of all living things depends on temperature, precipitation, altitude, soils, geography and the presence of other species.The study of the spatial distribution of organisms, species and ecosystems, is the science of biogeography.

Causes of the loss of biodiversity. The main cause of the loss of biodiversity can be attributed to the influence of human beings on the world’s ecosystem, In fact human beings have deeply altered the environment, and have modified the territory, exploiting the species directly, for example by fishing and hunting, changing the biogeochemical cycles and transferring species from one area to.

BIODIVERSITY. The Earth’s biodiversity — the variation of life at all levels — is the result of 4 billion years of evolution. And now it’s vanishing in the blink of an eye. Under relentless pressure from exploding human populations, animal and plant species are going extinct at 100 to 1,000 times the natural rate. The diversity of life that sustains both ecological systems and human.

Biodiversity is a measure of how many different species live in an ecosystem. Human activities like changing land use, deforestation and peat bog destruction reduce this. Biology (Single Science.
