More people require more vehicles which emit more carbon dioxide and create other impacts on the planet unless something is done quickly. Speed of Ocean Acidification Concerns Scientists September 26, The dramatic decline of the orangutan population, United Nations Population Division "Ocean acidification has happened before sometimes with large consequences for marine ecosystems.
Support for the creation of marine reserves has been gaining momentum.
Birds even feed plastic bits to their young, killing their fledglings en masse. The term "commons" referred to pastureland that was available for everyone to graze his sheep in old England. A third of the marine life in that sea, which once fed all of Northern Europe, What worries Pelejero most is the rapidity of today's changes.
All eight species of bears can be found in zoos around the world. The skies were dark and dogs were howling. Vast blooms of algae-organisms that thrive in more acid and less alkaline seawater and are fed by pollution-have already rendered parts of the Baltic Sea pretty much dead.
Another 45, orangutans could disappear in the next 35 years to habitat loss alone. While it is too late to do much about the plastic already circulating in our oceans, which it will take thousands of years to degrade, we can take action against future pollution by advocating the use of biodegradable materials and by changing consumer attitudes and behaviour.
The mother bears are killed in order to obtain cubs young enough to tame. Thousands more have died due to the widespread deforestation caused by the cultivation of palm oil. Fisheries off the coast of New England soon followed. So their stocks have plummeted over 90 percent in just the last 30 years.
Many of the estimates of species loss are extrapolations based on the global destruction of rain forests and other rich habitats. Second, they are disappearing even faster than researchers had envisioned.
Writing in the journal Current Biologythe team describe how the decline in nests from to points to the staggering loss oforangutans in Borneo. Some 9 percent of the world's tree species are at risk of extinction; tropical deforestation may exceedsquare kilometers per year. Their forests homes have been lost and degraded, and hunting threatens the existence of this magnificent great ape.
Human-caused carbon dioxide emissions in the atmosphere are being absorbed by the ocean and may have pushed local waters through a "tipping point" of acidity beyond which shellfish cannot survive, according to Chris Harley, a marine ecologist at the University of B.
Official catch data from FAO rarely includes small-scale, sport or illegal fishing and does not count fish discarded at sea. Few could catch the fish until the s and s when bigger, faster boats were designed. The same shifts that happened over the course of a few thousand years during the PETM Paleocene-Eocene Thermal Maximum are now due to happen over just a few centuries, counting from the beginning of the Industrial Revolution and the widespread use of fossil fuels.
For decades governments have tried to save specific fisheries by restricting the catch of individual species. Birds, fish and other animals are known to regularly consume plastic waste, mistaking it for jellyfish or other prey, but it cannot be digested and remains in the stomach.
A much larger number of orangutans were lost in selectively logged and primary forests, where rates of decline were less precipitous, but where far more orangutans are found. More than times the bile can be obtained by milking a live bear than by killing one.
The oversized and well-financed tuna fleet can easily take 50, tonnes in the Mediterranean and East Atlantic, despite a quota allowing only 29, tonnes. The oceans are taking up the greenhouse gases that we dump into the air, which turns the waters deadly to its inhabitants.
Carbon dioxide pollution is also being absorbed by the ocean, causing its chemistry to change and become more acidic. When you finish, go back and begin to click on the links to read the full articles. Even worse, selfish people can deplete the resource, so eventually no one benefits from it.
Jeremy Hance Seabirds have been around for sixty million years, and they are true survivalists: Poachers in the Philippines destroy vital reefs to meet that demand.
Regrettably, unbridled use of a resource is likely to lead to its depletion. Most of us learned to share in kindergarten.
This suggests that further drivers, independent of land-use change, contribute to orangutan loss. In the end, large-scale actions to help seabirds could also go a long way in cleaning-up our increasingly trashed marine ecosystems.
Malta voted against the proposed ban while Sweden and Austria abstained. Consumers need to call on companies to adopt responsible policies, continue to tell them that people care.
Alex Renton Rising greenhouse gases in the atmosphere are causing global temperatures to rise, which is leading to the melting of the polar ice caps, which in turn has resulted in rising sea levels and a host of ecological issues.As a follow-up to Tuesday’s post about the majority-minority public schools in Oslo, the following brief account reports the latest statistics on the cultural enrichment of schools in Austria.
Vienna is the most fully enriched location, and seems to be in roughly the same situation as Oslo. Many thanks to Hermes for the translation from fmgm2018.com The table below presents an abbreviated geologic time scale, with times and events germane to this essay.
Please refer to a complete geologic time scale when this one seems inadequate. WOA!
World Population Awareness is a non-profit web publication seeking to inform people about overpopulation, unsustainability, and overconsumption; the impacts, including depletion of natural resources, water, oil, soil, fertilizers, species loss, malnutrition, poverty, displacement of people, conflict; and what can be done about it: women's advancement, education, reproductive health care.
The majority of the Malayan sun bear’s forest habitat has been destroyed by logging and conversion to agriculture. In addition to leveling the forest, logging roads create convenient access for poachers.
As natural food sources disappear, sun bears are driven by hunger to forage for food on farms and plantations, where they are shot or trapped by angry farmers.
