Beavers escape storm, Basking shark conservation crucial.

  • Beavers install dams to slow water in ponds and channels, reducing downstream flow during storms.
  • A severe storm hits, causing substantial damage to the enclosure, allowing both beavers to escape.
  • The male beaver seeks refuge nearby, while sadly, the female dies.
  • The team plans to rebuild fences with a stronger design to welcome beavers back in the future.
  • The Sea of the Hebrides is a biodiverse area due to nutrient-rich cold water upwelling.
  • Zooplankton in the area attracts various fish species, sea birds, and the Basking shark.
  • The Basking shark, the second-largest shark, filters seawater through its gills like a sieve.
  • Basking sharks were hunted for their liver oil, leading to a decline in their population.
  • The Basking shark's life remains largely mysterious, with little known about their breeding habits.
  • Understanding Basking shark breeding and migratory patterns is crucial for their protection from climate change and other threats.

Sustainable Urban Farming: A Path to Conservation

  • Removing a farm from the environment would have minimal impact within three years, with the site returning to its original state.
  • Mussels play a crucial role in sustainability by cleaning surrounding water and absorbing carbon into their shells, providing a rich protein source with a low carbon footprint.
  • Aqua farming, especially for shellfish and fin fish, is seen as a sustainable solution to the increasing global population's food demands.
  • Technology advancements now allow for the growth of shellfish and fin fish on land, potentially leading to traditional livestock farmers branching out into aqua farming.
  • Urban environments may host ocean farms in the future, aiding in sea recovery and replenishment, with cities like London already implementing successful urban farming techniques.
  • Urban farming techniques, like those used by London-based Growing Underground, can produce pesticide-free microgreens that are 90 times more nutritious than fully grown counterparts, using renewable energy and less water.
  • Circular thinking in urban farming can repurpose wasted energy, such as heat waste from buildings, to power farms, making cities prime locations for food production.
  • Rewilding land by implementing new urban farming techniques can allow rural farms to return to nature, attracting wildlife back to the area.
  • The Isle of Aaron in Scotland showcases successful community-led efforts to protect marine habitats, leading to the establishment of Marine Protected Areas like Lamlash Bay.
  • Marine Protected Areas have shown significant recovery in marine life, with scallops and lobsters benefiting from the protection, emphasizing the importance of swift action in environmental conservation.
