Human-made ecosystems: Ecological novelty is now the "new normal" for our planet

"30-40% of the world's terrestrial ecosystems have already transformed into novel states."

"O'ahu as an "amazing crystal ball" that offers a glimpse of the future of our planet if humans continue to damage environments and drive species to extinction."

"Hawaii's O'ahu's lowland forests are now almost entirely devoid of the plants and animals that grew here for millions of years before the arrival of humans. Settlers brought extinctions by cutting down trees to make farms and introducing voracious predators and disease-carrying animals. Today, these tropical forests are a tapestry of non-native species introduced from every corner of the planet: Brazilian peppertree, Indonesian cinnamon and roseleaf bramble from the Himalayas and Australia. Most of the animals, including all the birds that Tarwater mentioned earlier, are also alien."

"We like to think of O'ahu as the cautionary tale for all the other Pacific Islands and the Hawaiian Islands. It's what you don't want to have happen – Corey Tarwater"

#Degrowth can work — here’s how science can help

Wealthy countries can create prosperity while using less materials and energy if they abandon #EconomicGrowth as an objective.

By Jason Hickel, Giorgos Kallis, Tim Jackson, Daniel W. O’Neill, Juliet B. Schor, Julia K. Steinberger, Peter A. Victor & Diana Ürge-Vorsatz, 12 December 2022

Excerpt: "The global economy is structured around growth — the idea that firms, industries and nations must increase production every year, regardless of whether it is needed. This dynamic is driving climate change and ecological breakdown. High-income economies, and the corporations and wealthy classes that dominate them, are mainly responsible for this problem and consume energy and materials at unsustainable rates.

"Yet many industrialized countries are now struggling to grow their economies, given economic convulsions caused by the COVID-19 pandemic, Russia’s invasion of Ukraine, resource scarcities and stagnating productivity improvements. Governments face a difficult situation. Their attempts to stimulate growth clash with objectives to improve human well-being and reduce environmental damage.

"GDP is getting a makeover — what it means for economies, health and the planet

"Researchers in ecological economics call for a different approach — degrowth. Wealthy economies should abandon growth of gross domestic product (#GDP) as a goal, scale down destructive and unnecessary forms of #production to reduce energy and material use, and focus economic activity around securing human needs and well-being. This approach, which has gained traction in recent years, can enable rapid #decarbonization and stop ecological breakdown while improving social outcomes. It frees up energy and materials for low- and middle-income countries in which growth might still be needed for development. Degrowth is a purposeful strategy to stabilize economies and achieve social and ecological goals, unlike recession, which is chaotic and socially destabilizing and occurs when growth-dependent economies fail to grow.

"Reports this year by the Intergovernmental Panel on Climate Change (#IPCC) and the Intergovernmental Science-Policy Platform on #Biodiversity and #Ecosystem Services (#IPBES) suggest that degrowth policies should be considered in the fight against #ClimateBreakdown and #biodiversity loss, respectively. Policies to support such a strategy include the following.

"Reduce less-necessary production. This means scaling down destructive sectors such as #FossilFuels, mass-produced meat and dairy, #FastFashion, #advertising, #cars and aviation, including #PrivateJets. At the same time, there is a need to end the #PlannedObsolescence of products, lengthen their lifespans and reduce the purchasing power of the #rich.

"Improve #PublicServices. It is necessary to ensure universal access to high-quality #HealthCare, #Education, #Housing, transportation, Internet, #RenewableEnergy and nutritious food. #UniversalPublicServices can deliver strong social outcomes without high levels of resource use.

"Introduce a green jobs guarantee. This would train and mobilize labour around urgent social and ecological objectives, such as installing renewables, insulating buildings, regenerating #ecosystems and improving social care. A programme of this type would end unemployment and ensure a just transition out of jobs for workers in declining industries or 'sunset sectors', such as those contingent on fossil fuels. It could be paired with a #UniversalIncome policy.

"Reduce working time. This could be achieved by lowering the retirement age, encouraging part-time working or adopting a four-day working week [and hybrid or remote work]. These measures would lower #CarbonEmissions and free people to engage in care and other welfare-improving activities. They would also stabilize employment as less-necessary production declines.

"Enable #sustainable development. This requires cancelling unfair and unpayable debts of low- and middle-income countries, curbing unequal exchange in international trade and creating conditions for productive capacity to be reoriented towards achieving social objectives.

"Some countries, regions and cities have already introduced elements of these policies. Many European nations guarantee free health care and education; Vienna and Singapore are renowned for high-quality public housing; and nearly 100 cities worldwide offer free public transport. Job guarantee schemes have been used by many nations in the past, and experiments with basic incomes and shorter working hours are under way in Finland, Sweden and New Zealand.

"But implementing a more comprehensive strategy of degrowth — in a safe and just way — faces five key research challenges, as we outline here."

When #marine animals ingest #DomoicAcid, they endure severe neurological symptoms such as seizures, disorientation, &, ultimately, death. These incidents often necessitate euthanasia due to the high mortality rates associated w/this toxin. This alarming rise in domoic acid poisoning cases not only threatens individual #MarineSpecies but also highlights the broader impacts #humans have on marine #ecosystems.

Continued thread

#Wildfires, including the #EatonFire & #PalisadesFire, have significant repercussions on #marine #ecosystems. The ash & debris from these fires can enter waterways & eventually the #ocean, altering nutrient levels & fostering conditions favorable to the growth of harmful #AlgalBlooms. The #toxic byproducts from these fires can exacerbate #OceanWarming, further promoting the frequency of these toxic blooms. This can lead to increased production of #DomoicAcid.

Continued thread

#DomoicAcid is a potent neurotoxin produced by certain phytoplankton species, which are significant contributors to harmful #AlgalBlooms. These toxins accumulate in the tissues of #MarineMammals & other #wildlife consuming contaminated prey. Recent changes in #ocean conditions,…intensified by #environmental factors such as the #EatonFire & #PalisadesFire, have accelerated the proliferation of these harmful algal blooms.

we are living through an #ExtinctionCrisis unlike anything in human history—over a million #species are at risk of disappearing in the coming decades. #ecosystems that have taken millions of years to evolve are unravelling before our eyes, driven by #HabitatDestruction, #climate chaos, #pollution, and endless #extraction. every species lost is a thread pulled from the web of life, and sooner or later, that web collapses. ⁠

“It really shows that we have a unique place in #Michigan where someone has a chance to see a #wolf, a #moose & a #cougar in the #wild. It’s something that should be celebrated, that we have the #habitat to support an elusive animal like this,”Roell said.

The cubs were spotted & photographed without their mother. #CougarCubs are highly dependent on their mothers, often staying with them for the first two years of life.

Continued thread

This is the first time #CougarCubs have been verified since the big cats were hunted out of existence in #Michigan in the early 1900s, said Brian Roell, large carnivore specialist for the MDNR. Roell, a #wildlife biologist for 26yrs, led the team that verified the cubs.

“It’s pretty exciting, considering this could be the first known cougar reproduction in modern times in the western #GreatLakes states,”said Roell, referring to Michigan, Wisconsin & Minnesota.

Ecologists contend with the fact that many ecosystems we love and want to restore and rewild are in fact human-created ecosystems. Native plants in these systems are indeed native but selected by humans in human-created ecosystems. Which means insects, animals and other biota in those systems are influenced by humans.

We will never go back to pre-human ecosystems. Our world is shaped by our behavior. We depend on our world to survive. Our world depends on us to survive. We depend on each other to survive.

We are part of nature, we shape nature, we try to optimize it for our survival. We are natural beings. We are part of the world's ecosystems.

🌿 I want ecosystems to be our priority. I want vast areas of grassland & forests to be reclaimed for indigenous species here in Southern Alberta. New research from @UMich shows that large #conservation areas are more effective than small ones at preserving species & #ecosystems. Scaling up habitat protection helps maintain genetic diversity & #climate resilience. As #habitat loss accelerates, expanding protected areas is key to safeguarding #nature.
