A team at British Antarctic Survey (BAS) examined the potential distribution of over 900 species of shelf-dwelling marine invertebrates under a warming scenario produced by computer models. They conclude that, while some species in some areas will benefit, 79% of the species native to the region will lose out. This has important implications for future resource management in the region.
Climate change and habitat conversion to agriculture are working together to homogenize nature, indicates a study in the journal Global Change Biology led by the University of California, Davis.
In other words, the more things change, the more they are the same.
While the individual impacts of climate change and habitat conversion on wildlife are well-recognized, little is known about how species respond to both stressors at once.
What is Biodiversity?
Biodiversity is fundamental as it ensures natural sustainability of all life on earth not only for the current population but also for the future generations. However, biodiversity continues to be threatened and in consequence, it affects the survival of humans. Various concerns have been raised by environmental advocates and agencies such as the UNEP, WWF, GreenFacts Foundation, and EPA with regards to the threats posed on many of the world’s ecosystems which are increasingly deteriorating in state by becoming unhealthy and unbalanced.
What is a Biodiversity Hotspot?
Biodiversity hotspots are regions that are both biologically fertile (rich distribution of plants and animals) and highly threatened. In other words, such biogeographic regions are very productive and are constantly exposed to threats of destruction which warrant the need for them to be protected. Examples of biodiversity hotspots are forest habitats as they constantly face destruction and degradation due to illegal logging, pollution and deforestation.
An international team of scientists has issued a warning that biodiversity is dropping below safe levels for the support and wellbeing of human societies.
As a species we are inextricably connected with the processes of our local ecosystems, such as crop pollination, waste decomposition and regulation of the carbon cycle.
These ecosystems depend on the biological diversity within them to function.
The planetary boundaries framework updated in 2015 states that losing more than 10% of the biodiversity in an area places the local ecosystem at risk.
It’s a politically and ethically charged debate. Can hunting animals really contribute to wildlife conservation and biodiversity objectives? On first glance, hunting as a means of conservation seems like an inherent contradiction. Yet the sustainable use of wildlife has been ratified by the Convention on Biological Diversity (CBD) as a central means of conserving biodiversity. So is hunting sustainable and does it actually incentivise conservation? And is it really the right way to sustain biodiversity?
The diversity of plants and animals in Earth's arctic regions is moderate. Tropical latitudes in contrast are teeming with different species where new organisms are being discovered all the time.
For centuries, humanity has seen the sea as an infinite source of food, a boundless sink for pollutants, and a tireless sustainer of coastal habitats. It isn’t. Scientists have mounting evidence of rapidly accelerating declines in once-abundant populations of cod, haddock, flounder, and scores of other fish species, as well as mollusks, crustaceans, birds, and plants. They are alarmed at the rapid rate of destruction of coral reefs, estuaries, and wetlands and the sinister expansion of vast “dead zones” of water where life has been choked away.
The fewer animals we have, the fewer humans we will have.
That's why biodiversity is important. The wide variety of species on Earth, whether they're plants, animals or microscopic organisms, are vital to keep the world's many ecosystems healthy, balanced and thriving — growing plants we can eat, trees we can shade under, and landscapes to use for everything from vacations to computer screensavers.
