"Shark tagging expedition reveals elusive predators"

Greg SCL had a close encounter with a white shark with its jaws open right under him, but he emphasizes that the probability of being bitten is low due to primal fear.
A team joined a shark tagging expedition off Nova Scotia on a research ship called Urch, using long lines and bait to hook white sharks for tagging.
Fishing master Brett McBride guided an 1100lb male white shark onto a platform on Urch, where a hose was inserted between its jaws to keep clean seawater flowing over its gills.
The team took blood and tissue samples, measured the shark's girth and length, and attached an acoustic tag to track the shark's movements in real-time for up to 5 years.
Osearch's techniques, though criticized as invasive, provide valuable data from a single shark to 17 research projects, revealing unknowns about white sharks' behavior and lifespan.
Adult white sharks travel from Cape Cod to Florida and the Gulf of Mexico, diving to depths of 3000 ft daily, living over 70 years and starting to hunt seals in their late teens.
The fear of shark attacks on Cape Cod has risen, despite rare incidents, leading to safety measures like warning signs, shark sighting apps, and community meetings.
Osearch named a white shark Sydney and released it back into the water unharmed after monitoring its stress levels, emphasizing the importance of conservation and understanding these elusive creatures.

Carr's project in Gorongosa also focuses on improving the lives of local communities through employment, tourism, healthcare, and education initiatives.
Carr's foundation has partnered with the government to support education, healthcare, and economic opportunities for the local population, including programs for vulnerable girls to pursue education and career paths.
Carr's model for conservation includes empowering local communities to take ownership of their land and resources, inspired by Nelson Mandela's vision of a human rights park.
Despite facing challenges like civil wars and natural disasters, Carr remains committed to his conservation efforts, with a focus on protecting endangered species like Pangolins and creating a sustainable ecosystem where wildlife is valued alive.

Zoo euthanizes giraffe despite public outcry

Marius, a young giraffe, faced aggression from his father in the zoo, leading to concerns for his safety.
Suggestions to release Marius into the wild were deemed impractical due to the lack of space and social needs of giraffes.
Despite offers from individuals to take Marius, the zoo prioritized his welfare and decided to euthanize him.
The zoo defended the decision, stating that culling healthy animals is sometimes necessary for population health and future sustainability.
Animal rights activists criticized the zoo's actions, highlighting the ethical dilemma of killing healthy animals.
Ron Kagan from the Detroit Zoo opposes culling, emphasizing individual animal welfare over genetic conservation.
Zoos have been improving animal welfare standards, with Detroit Zoo leading efforts to create natural habitats for animals.
The public autopsy of Marius and feeding his remains to lions sparked controversy and criticism.

Wild Mustangs: From Freedom to Training

In Northern Wyoming, a Thundering Herd of Mustangs roams the badlands, untouched and wild, but their overpopulation poses a threat to the environment.
The Federal Bureau of Land Management rounds up wild horses using helicopters and places them in sanctuaries like the Wind River Wild Horse Sanctuary in Lander, Wyoming.
The sanctuary, run by Jess Oldum and his family, cares for 225 long-term resident Mustangs on a 1400-acre facility on an Indian Reservation.
Activists advocate for wild horses to remain free, but the delicate ecosystem requires proper management due to limited resources like grass and water.
The government currently cares for over 57,000 wild horses, costing taxpayers over $70 million annually for their care in off-range corrals and pastures.
An incentive program pays individuals $1,000 to adopt a wild horse, with selected horses sent to places like the Wyoming Honor Farm for training by inmates.
Inmates at the Wyoming Honor Farm work to transform wild Mustangs into trained riding horses, learning life lessons and gaining skills in the process.
Training a wild horse involves patience, persistence, and trust-building, with inmates like Michael Davis finding a sense of freedom and responsibility through the program.
The Wyoming Honor Farm holds auctions where trained Mustangs are sold, fetching thousands of dollars and providing a second chance for both horses and inmates.

Restoring Bison to American Prairie: A Vision

American Prairie aims to restore Bison to a landscape they once dominated, with a conservation herd of about 800 Buffalo, mainly mothers with distinctive red calves.
The nonprofit's goal is to create the largest Nature Reserve in the contiguous United States, spanning 3.2 million acres of intact grasslands, comparable in size to Connecticut, Glacier, and Yellowstone National Parks combined.
The Reserve is primarily located north of the Missouri river in North Central Montana, comprising privately owned cattle ranches and government-owned land, including the Charles M Russell National Wildlife Refuge.
American Prairie has purchased 34 ranches, raising nearly $200 million from over 4,000 owners, including Wall Street financiers and Technology Moguls, with the aim of acquiring more land to complete their vision.
The organization is working to restore the prairie ecosystem to its former state, teeming with Bison, Native Americans, and wildlife, aiming for the ecosystem to function fully as it once did.
American Prairie's Wild Sky program incentivizes sustainable ranching practices, paying ranchers up to $115,000 annually for wildlife-friendly modifications like fences and camera installations.
The organization collaborates with cattle ranchers like Lance Johnson, who sees working with American Prairie as a way to secure his family's future, aiming to coexist with the local community and tribes like the Fort Belnap reservation, who have their own bison herd and value the land beyond monetary terms.
