Organisation	Recommended Starting Age	Frequency
ACP (2026)	50 (40–49 is individual choice)	Every 2 years

• 3D Mammography (Tomosynthesis): Takes multiple X-rays from different angles to create a "sliced" 3D view. It is more accurate for dense breast tissue.
• AI Integration: AI software now assists radiologists by flagging suspicious areas and predicting a woman’s 5-year cancer risk from a single scan.
• Contrast-Enhanced Mammography (CEM): Uses an iodine-based dye to highlight abnormal blood flow around tumours, similar to an MRI but at a lower cost. 

• False Positives: A mammogram may look abnormal when no cancer is present, leading to "call-backs" and unnecessary biopsies.
• False Negatives: Mammograms miss roughly 15%–20% of breast cancers, particularly in very dense breasts.
• Radiation: While it uses radiation, the dose is extremely low and considered safe for regular annual or biennial use. 

• "Living Fossils": Tapirs have changed very little in appearance over tens of millions of years, dating back to the Eocene epoch.
• Prehensile Snout: Their short, flexible trunk is an extension of the nose and upper lip, used to grab leaves, fruits, and even as a "snorkel" while swimming.
• The "Odd-Toed": They are perissodactyls (odd-toed ungulates), having four toes on their front feet and three on their back feet.
• Aquatic Skills: Excellent swimmers that often retreat to water to escape predators or cool down. 

• Seed Dispersal: They consume large quantities of fruit and travel long distances, dispersing seeds through their dung, which is critical for forest regeneration.
• Umbrella Species: Protecting tapir habitats automatically protects thousands of other species (birds, insects, deer) that share their massive territory. 

Species	Region	IUCN Status	Key Fact
Malayan Tapir	Southeast Asia	Endangered	Largest species; distinctive black-and-white "waterline" camouflage.
Baird's Tapir	Central America	Endangered	Largest land mammal in Central America.
Lowland Tapir	South America	Vulnerable	Most widespread; found across the Amazon Basin.
Mountain Tapir	High Andes	Endangered	Rarest species; has a thick woolly coat for cold altitudes.

• Habitat Loss: Deforestation for palm oil (Asia) and soy/cattle farming (South America) destroys their territory.
• Roadkill: In Peninsular Malaysia, over 200 tapirs have been killed by vehicle collisions in the past 15 years.
• Slow Reproduction: Females have a very long gestation period (13–14 months) and give birth to only one calf at a time, making population recovery extremely slow. 

• Founded: Created in September 1960 at the Baghdad Conference.
• Founding Members: Iran, Iraq, Kuwait, Saudi Arabia, and Venezuela.
• Headquarters: Located in Vienna, Austria (moved from Geneva in 1965).
• OPEC+: Formed in 2016 to include 10 non-OPEC members like Russia, Kazakhstan, and Oman to better control market prices. 

• 12 Members: Algeria, Congo, Equatorial Guinea, Gabon, Iran, Iraq, Kuwait, Libya, Nigeria, Saudi Arabia, UAE (exiting), and Venezuela.
• Exits: The UAE joins a list of recent departures including Angola (2024), Ecuador (2020), and Qatar (2019). 

• Price Stability: Coordinating production levels to avoid wild price fluctuations.
• Supply Management: Ensuring a steady supply of petroleum to consuming nations.
• Investor Returns: Securing fair returns for those investing in the petroleum industry.
• Research: Publishing the Monthly Oil Market Report (MOMR) and Annual Statistical Bulletin for industry transparency. 

• Reserves: OPEC nations hold approximately 80% of the world's proven crude oil reserves.
• Production Share: OPEC produces about 30% of world crude, while the wider OPEC+ group accounts for nearly 50% of global oil liquids production.
• Influence: By adjusting production targets, OPEC significantly impacts global fuel costs, transport markets, and national economies.

• Timeline: Started ~11,700 years ago at the end of the Pleistocene.
• Meaning: Derived from the Greek words holos (whole/entire) and kainos (new), meaning "Entirely Recent."
• Climate: Characterized by a relatively stable, warm climate compared to the volatile glacial periods of the past. 

1. Greenlandian (Early): 11,700 to 8,200 years ago; marked by rapid warming.
2. Northgrippian (Middle): 8,200 to 4,200 years ago; began with a major cooling event.
3. Meghalayan (Late): 4,200 years ago, to the present; began with a massive global drought that impacted ancient civilizations (named after a stalagmite found in Meghalaya, India). 

• Rise of Civilization: The stable climate allowed humans to transition from hunter-gatherers to farmers (the Neolithic Revolution).
• Agriculture: Almost all crops’ humans eat today were domesticated during this epoch.
• Sea Levels: Sea levels rose by about 120 meters early in the Holocene as ice sheets melted, creating the modern coastlines we see today. 

• Mass Extinction: We are currently in the Sixth Mass Extinction, often called the Holocene extinction, driven by human activities like habitat destruction and pollution.
• Loss of Megafauna: The early Holocene saw the disappearance of "Ice Age" giants like mammoths, mastodons, and sabre-toothed tigers. 

• Holocene: Defined by natural climate cycles and solar orbital changes.
• Anthropocene (Proposed): Defined by radioactive fallout, plastic pollution, and massive CO2 increases caused by humans since the mid-20th century. 

• Scientific Name: Ardeotis nigriceps.
• Appearance: Tall with long legs and a long neck; resembles an ostrich. Males have a large black cap and a gular pouch used during mating displays.
• Weight: Can weigh up to 15 kg, making it one of the heaviest flying birds.
• Diet: Omnivorous; feeds on grass seeds, insects (like grasshoppers), beetles, and occasionally small rodents or reptiles. 

• Ecosystem: Found in dry grasslands and scrublands (often called the "Flagship species of grassland ecology").
• Primary Range: Over 90% of the population is confined to the Desert National Park (DNP) in Rajasthan.
• Other States: Small, fragmented populations exist in Gujarat (Lala-Parjan sanctuary), Maharashtra, and Karnataka. 

• IUCN Red List: Critically Endangered.
• CITES: Appendix I.
• Wildlife Protection Act (India): Schedule I (highest protection).
• Population: Estimated at fewer than 150 individuals globally. 

• Overhead Power Lines: The biggest threat. GIBs have poor frontal vision and cannot see cables while flying, leading to fatal collisions.
• Habitat Loss: Conversion of grasslands into agricultural land or industrial zones (solar/wind farms).
• Predation: Feral dogs and crows often eat GIB eggs, which are laid directly on the ground.
• Slow Breeding: A female GIB lays only one egg per year. 

• Project Great Indian Bustard: A Rajasthan state government initiative for habitat restoration and fencing.
• Conservation Breeding Centres: Facilities in Sam and Ramdevra (Rajasthan) are working on "egg-to-flight" reintroduction programs.
• Supreme Court Intervention: The court is monitoring the "undergrounding" of power lines in a 13,000 sq km area to create a safe flight corridor.
