5 fascinating facts about sharks, the world s ultimate apex predator

5 fascinating shark facts By Megan Marples, CNN © naturepl.com / Doug Perrine / WWF The population of hammerhead sharks in the Sea of Cortez, between Baja California and the Mexican mainland, has seen a steep decline due to overfishing. Sharks have called the Earth s oceans home for hundreds of millions of years and adapted to thrive in harsh environments. While these top hunters of the deep blue have evolved to survive cold and dark climates, sharks are no match for the ultimate predator humans. That s why Shark Week, running from July 11 through July 18, was launched 33 years ago by Discovery Channel to encourage shark conservation and educate the public on these underwater predators.

Nature-Based Solution to Climate Change Shows Enormous Potential

Freshwater  Freshwater Freshwater habitats such as rivers and wetlands have high biodiversity, but this is being endangered by climate change, increasing the likelihood of floods and drought due to shifting rainfall patterns. Professor Chris Spray, the lead author of the Freshwater chapter at the University of Dundee, said: Protecting these endangered habitats would necessitate a wholescape catchment solution that integrates ecological, cultural, and socioeconomic processes. Planting trees along riverbanks, for example, will preserve habitats by providing shelter and building thermal refuges, as well as slowing the flow of water to help mitigate flood risk. Grasslands  (Photo : Wikimedia Commons) Grazing grasslands by a diverse range of animals on the same landscape, such as sheep, cattle, horses, goats, and alpacas, will improve grassland sward diversity and greenhouse gas emissions. Emissions can also be reduced by switching from constant grazing to rotational or hybrid

Wetland ecosystems are carbon storage power houses , expert says

The UK must ‘learn to love’ its peat bogs as they are carbon storage ‘powerhouses’, an expert said yesterday. Peatlands in Britain contain around three billion tons of carbon – about three times the amount that forests store – according to a report by the British Ecological Society. Dr Christian Dunn, of Bangor University, wrote: ‘[Peatlands] are giant security vaults full of carbon but unfortunately these carbon vaults can be broken into, the doors can be blown off and when that happens the carbon is released. We have damaged so much of these carbon vaults.’ Peat is formed by layers of dead moss, which captures carbon as it builds up. Bogs are also an important home to wildlife and provide clean water.
