Notes:
Namami Gange mission is run by the Central
Government in five states namely
Uttarakhand, Uttar Pradesh, Jharkhand,
Bihar and West Bengal. It is managed by West Bengal Forest Department for
sustaining the biodiversity of the Ganga river ecosystem along with its
purification.

Notes:
Reverse osmosis (RO) is a water purification technology that uses a semipermeable membrane to remove ions, molecules, and larger particles from drinking water. It can remove many types of dissolved and suspended species from water, including bacteria, and is used in both industrial processes and the production of potable water (Desalination of marine water). It is most commonly known for its use in drinking water purification plants particularly in countries of middle east.

Notes:
During the plateau phase, population size is constant so no more growth occurs. This is the result of natality rate being equal to mortality rate and is caused by resources becoming scarce as well as an increase in predators, diseases and parasites.

Notes:
Manas National Park is located in the Himalayan foothills of Assam. It is also a UNESCO Natural World Heritage site, a Project Tiger Reserve, and Elephant Reserve. It is contiguous with the Royal Manas National Park in Bhutan. Manas is famous for its population of the wild water buffalo.

The Península Valdés, recognized as a UNESCO World Heritage Site in 1999, provides a sanctuary for marine mammals, hosting half of the world’s southern right whale population. The conservation area, located in Argentina, also houses breeding colonies of southern elephant seals and sea lions. A unique hunting strategy has evolved among its resident orcas. Furthermore, the 400,000-hectare desert-like headland features towering cliffs, expansive gulfs, and sandy beaches. Discovered by a Spanish expedition in 1779, it shows signs of Neolithic occupation like obsidian tools. The peninsula, divided into five sections, each offering unique attractions like whale watching, is home to myriad bird species, penguins, maras, and guanacos.

Notes:
The Gondwana Rainforests, designated as a World Heritage Site, are located in southeast Queensland and northeast New South Wales in Australia. They personify extraordinary instances of Earth’s evolutionary phases, with over 50 sheltered areas playing host to more than 200 rare or endangered species. These rainforests are remnants from the ancient supercontinent Gondwana, evident through tree lineages such as Red and Yellow Carabeen. Unfortunately, they are threatened by climate change and provide important habitats for scarce species like the Hastings River Mouse and Parma Wallaby. Drawing around 2 million tourists each year, these vast rainforests cover an impressive 366,500 hectares.
