Obtained enormous global visibility and tremendous response from the authors and readers from all over the world inspired the publisher to maintain reputed Open Access Journals in various scientific disciplines.
Human beings are currently causing the greatest mass extinction of species since the extinction of the dinosaurs 65 million years ago. If present trends continue one half of all species of life on earth will be extinct in less than years, as a result of habitat destruction, pollution, invasive species, and climate change.

New articles are added regularly. Most recent update September 17, Although scientists are divided over the specific numbers, many believe that the rate of loss is greater now than at any time in history. Nearly seven out of 10 of the biologists polled said they believed a "mass extinction" was underway, and an equal number predicted that up to one-fifth of all living species could disappear within 30 years.
Nearly all attributed the losses to human activity, especially the destruction of plant and animal habitats. Among the dissenters, some argue that there is not yet enough data to support the view that a mass extinction is occurring.
Many of the estimates of species loss are extrapolations based on the global destruction of rain forests and other rich habitats. Among non-scientists, meanwhile, the subject appears to have made relatively little impression. Sixty percent of the laymen polled professed little or no familiarity with the concept of biological diversity, and barely half ranked species loss as a "major threat.

The large number of extinctions spans numerous families of plants and animals, including mammals, birds, amphibians, reptiles and arthropods. Top 10 of natural and anthropogenic environmental disasters.
The link between climate change and biodiversity has long been established. Although throughout Earth’s history the climate has always changed with ecosystems and species coming and going, rapid climate change affects ecosystems and species ability to adapt and so biodiversity loss increases.
The Great Lakes form the largest surface freshwater system on Earth.
More than 30 million people live in the Great Lakes basin, and the impact of their daily activities, from the water consumed to the waste returned, directly affects the Great Lakes environment. Human impact on biodiversity and ecosysytem loss Magdaléna Jilečková The English College in Prague Abstract Biodiversity and ecosystem are crucial issues that have an impact to the human well-being now and in the r-bridal.comersity depends on many factors but the most influentive is the habitat loss which influences the biodiversity worldwide.
Order Chiroptera is the second most diverse and abundant order of mammals with great physiological and ecological diversity.
They play important ecological roles as prey and predator, arthropod suppression, seed dispersal, pollination, material and nutrient distribution, and recycle. They have great advantage and disadvantage in economic terms.
