One in three species of cacti is threatened with extinction—and poachers are not helping. But self-styled vigilante conservationists tell 1843 they’re saving plants by snatching them from the wild https://t.co/m6rILglJs0 ...

Environmental Impact & Conservation - Over one-third (33%) of all shark and ray species are threatened with extinction worldwide, equating to over 400 species [3] - Declining shark and ray populations have been linked to the functional extinction of seagrass meadows in the Indian Ocean and threaten coral reefs in Australia [4][5] - Sharks and rays play a crucial role in regulating the ocean's ecosystem and maintaining its balance [15] Research & Biodiversity - There are over 50 species of sharks and rays in Port Philip Bay, Australia, many of which are meso predators [8] - Research focuses on tracking shark and ray movements using small trackers and underwater listening stations to understand their role in the marine ecosystem [11][12] - Muscle biopsies are used to analyze the diet of sharks and rays, providing insights into their ecological roles [13] Threats & Human Impact - Overfishing is the number one threat to sharks and rays globally [17] - Shark products are present in everyday items like pet food, supplements, and skincare [17][18] - Three billion people rely on marine and coastal resources for their livelihoods, highlighting the importance of ocean conservation [15] Ocean's Role - The ocean provides 50% of the air we breathe, emphasizing the critical role of marine ecosystems [15]

Demographic Trends - White population has decreased significantly over the past 100 years [1] - White population percentage: 100 years ago roughly 35%, 50 years ago roughly 20%, 25 years ago 15%, today just 8% [1] Social Commentary - The report suggests a perceived need for White people to "take their countries back" [1] - The report expresses a sentiment against tolerance and empathy [1]
The call from the animals | Inaya Matta | TEDxTarneit Youth

Imagine waking up one morning and discovering that every single elephant, tiger, or even a colorful parrot in the world had disappeared. The forest would be sad, the savannah's empty, and the sky far less bright. No roar of a light, no flutter of wings, no sound of birds greeting the morning.It may sound like a sad story, but it's one that's already unfolding. Scientists estimate that about 1 million species are now at risk of extinction. And every day, more animals are pushed closer to disappearing forever ...

De-extinction Project & Biodiversity - Biodiversity is projected to decrease by 27% in vertebrates by 2050 [1] - Colossal Laboratories and Biosciences claims to have brought back an extinct species of wolf, the direwolf [2] - Colossal aims to resurrect extinct species by generating organisms resembling and genetically similar to them, focusing on core genes [8] - Colossal plans to reintroduce woolly mammoths by 2028, along with projects involving the thylacine and dodo bird [15] Direwolf Project Details - Colossal used gene editing and cloning from ancient samples (13,000-year-old tooth and 72,000-year-old skull) to recreate direwolf pups [4] - Colossal identified 20 differences in 14 genes between grey wolf and direwolf genomes, accounting for distinguishing characteristics [5] - Direwolves existed from approximately 4 million years ago to 10,000 years ago, growing up to 178 cm and weighing 59-68 kg [9][10] - CRISPR technology was used to edit the genes, with five genes changed solely for the white coat characteristic [11][13] Species Definition & Project Validity - The definition of species involves interbreeding, while Colossal uses the morphological species concept (if they look like the animal, they are the animal) [6][7] - Greywolves are genetically more similar to jackals and African wild dogs than to direwolves [10] - Colossal currently has no plans for breeding the direwolves, which impacts the ability to determine if they can produce fertile offspring [14]

Environmental Crisis & Indigenous Knowledge - The world is facing a sixth major extinction event, necessitating preservation of wilderness and biodiversity [1] - Indigenous people, comprising less than 5% of the global population, manage over 40% of the world's untamed landscapes, spanning millions of square kilometers [2][3] - Integrating cultural knowledge and ecological wisdom from indigenous communities with emerging technologies can help solve conservation crises [26] Challenges & Solutions for Technology Adoption - Commercial off-the-shelf drones have a short lifespan (approximately 3 weeks) in remote indigenous communities due to their complexity and vulnerability to harsh environments [8][9] - Compliance requirements and training needs pose barriers to drone adoption by indigenous communities [9][10] - Processing and managing the thousands of drone imagery requires high-performance computing, which is often unavailable in remote areas [11][12] - Charles Darwin University is addressing these challenges by redesigning drones (e g, the Bimmeran), providing indigenously focused training, and utilizing AI and satellite technology (e g, Starlink) for data processing [12][13][16] Drone Technology Application & Impact - Drones provide an affordable aerial view for strategizing, coordinating, and assessing environmental management actions [5] - Drones are used in agriculture, park management, and conservation, but adoption in indigenous communities is limited [6][7] - In Groot Island, drones are used to map marine plastic debris, enabling rangers to strategize removal efforts and improve marine environment, covering over a thousand kilometers of coastline with only 12 rangers [17][20][22] - The drone program helps Australia meet its global biodiversity targets and is expanding to address various land management issues with multiple indigenous groups [23]

Biodiversity Crisis & Interdependence - The world's wildlife has been reduced by nearly 73% in the last 50 years, highlighting an emerging catastrophe [8] - Honeybees pollinate nearly 80% of the world's flowering plants and major crops, crucial for modern civilization, but their population is being decimated [4] - Plants and animals are intertwined with humans, bringing important bio-knowledge, critical for health and well-being, and companionship [3][4][7][24] Conservation Efforts & Solutions - Resuscitating the Judean date palm from 2,000-year-old seeds demonstrates the potential for mitigating catastrophes with resources and will [9][10][11] - The Svalbard Global Seed Vault safeguards seeds needed for humanity's food supply, but rising sea levels pose a threat [13][14] - Cryogenics allows freezing and storing individual cells of plants and animals for eternity, with states like California actively freezing endangered cells [15][16] Lunar Ark Concept - The lunar ark, a facility built in lunar lava tubes, could store 90% of Earth's biodiversity cryogenically [19] - Lunar lava tubes offer ready-made shelters against radiation, extreme temperatures, and micrometeorites [18] - The lunar ark would be powered by nuclear fission reactors and operated by robots, functioning like a robotic library [19][20] - Resuscitated species from the lunar ark could be grown to maturity in orbiting terrariums and eventually returned to Earth [22]
