The Importance of Old Growth Forests The Nature Trust of British Columbia

"...Old growth forests are awe-inspiring and highly diverse ecosystems that can be found all around the world. They play essential roles in wildlife habitat, species diversity, hydrological regimes, nutrient cycles, carbon storage, and numerous other ecological processes. They have special structures and characteristics that provide habitat for animal and plant species, such as bats, birds, lichen, and mammals which are not found in any other forest types..."

Deforestation darkening the seas above world's second biggest reef

"...Stacey Felgate, a PhD Student at the University of Southampton and the National Oceanography Centre, led the study working with partners in Belize. Stacey said, "Like many countries in the region, Belize is experiencing a rapid rate of deforestation due to increasing need for agricultural and urban land, whilst the economy also relies on the fishing and tourism industries on the coastline. Despite this, there has been very little research into the impact that changing land-use at such a fast pace is having on the region's coastal ecosystems..."

Belowground biodiversity in motion

"...Soil microorganisms play a critical role in the survival of life-sustaining ecosystems and, consequently, human well-being. Global assessments continue to provide strong evidence that humans are causing unprecedented biodiversity losses. However, existing information is strongly biased towards selected groups of vertebrates and plants, while much less is known about potential shifts in belowground communities..."

Climate warming linked to tree leaf unfolding and flowering growing apart

"...Dr Qianqian Ma, lead author of the study said "The timing of phenological events is very sensitive to environmental factors, with temperature being particularly important in temperate plants. The changes in phenology we observed in our study may affect both growth and reproductive development in tree species and ultimately affect the ecosystem, nutrient cycles and carbon storage. "..."

Climate change exacerbates biodiversity loss

"...About a million plant and animal species are endangered worldwide. At least 13 of the 17 sustainable development goals of the United Nations, however, depend on biodiversity, including species diversity, the genetic diversity within species and the diversity of ecosystems. Biodiversity regulates fundamental processes, such as soil formation and water-, trace-gas-, and nutrient cycles and thus contributes notably l to regulating the climate..."

Species loss affects basis of life of humans

"..."The findings of the Jena Experiment confirm that current species loss has directly consequences for humankind," Wilcke says. "As a result, functions of nature that may apparently be taken for granted break off. " According to the geoecologist, examples are the production of biomass for food, fabrics, construction materials, and fuels as well as water and nutrient cycles..."

"...Photo by Mildly Useful on UnsplashMany people are calling for a just, green recovery from the COVID-19 pandemic. Investing in natural solutions to climate change, restoring damaged and fragmented ecosystems, strengthening the social safety net and rethinking flawed economic systems would make us more resilient to current and future crises.  ..."

Shrinking dwarves

"...Largely unnoticed and in secret, an army of tiny service providers works below our feet. Countless small insects, arachnids and other soil dwellers are indefatigably busy decomposing dead plants and other organic material, and recycling the nutrients they contain. However, experts have long feared that these organisms, which are so important for soil fertility and the functioning of ecosystems, are increasingly coming under stress..."

Scientists urge caution, further assessment of ecological impacts above deep sea mining

"..."The current study shows that mining and its environmental impacts may not be confined to the seafloor thousands of feet below the surface but could threaten the waters above the seafloor, too," said Drazen. "Harm to midwater ecosystems could affect fisheries, release metals into food webs that could then enter our seafood supply, alter carbon sequestration to the deep ocean, and reduce biodiversity which is key to the healthy function of our surrounding oceans. "    In accordance with UN Convention on the Law of the Sea (UNCLOS), the International Seabed Authority (ISA) is required to ensure the effective protection of the marine environment, including deep midwater ecosystems, from harmful effects arising from mining-related activities..."
