The Great Barrier Reef is the world's largest coral reef system, composed of over 2,900 individual reefs and 900 islands stretching over 2,600 kilometers off the coast of Queensland, Australia. It supports a wide diversity of marine life and was named a UNESCO World Heritage Site in 1981. The reef is made up of billions of tiny coral polyps and is the world's largest structure built by living organisms. It faces threats from climate change, runoff, bleaching events and crown-of-thorns starfish outbreaks. The Great Barrier Reef Marine Park helps manage activities like fishing and tourism to protect the ecosystem while also generating $1 billion annually for the local economy.
Importance of coral reefs & its propertiesDr. sreeremya S
As these corals grow and die, they leave behind their calcium carbonate skeletons. On these skeletons, other corals grow. As the year’s passes, walls of coral begin to form: massive walls of rock (Kleypas, 1999).
As the waves and currents beat upon these reefs, nooks, crannies, ledges and caverns form in these walls. Just as there are different types of corals, there are different types of coral reefs. The three major types of reefs are fringing reefs, barrier reefs and atolls(Langdon,2000).Like coral reefs , sponges are also a wonderful resource, which has immense applications (Sreeremya et al.,2018).
A coral reef is an underwater ecosystem characterized by reef-building corals. Coral reefs are important for many different reasons aside from supposedly containing the most diverse ecosystems on the planet. They:
• protect coastlines from the damaging effects of wave action and tropical storms
• provide habitats and shelter for many marine organisms
• are the source of nitrogen and other essential nutrients for marine food chains
• assist in carbon and nitrogen fixing
• nutrient recycling.
As part of our World Oceans Day celebration we created presentations designed to raise environmental awareness for key areas of our planet! This one is dedicated to Coral Reefs.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

7. A large part of the reef is protected by the Great Barrier
Reef Marine Park, which helps to limit the impact of
human use, such as fishing and tourism.
8. Other environmental pressures on the reef and its
ecosystem include runoff, climate change accompanied
by mass coral bleaching, and cyclic population
outbreaks of the crown-of-thorns starfish. According to
a study published on 1 October 2012 by the
Proceedings of the National Academy of Sciences, the
reef has lost more than half its coral cover since 1985.

Continental islands are the inn: ; of the mainland that
have been cut off by the changes in the sea level, and
some lie quite close to the coast and rise from the
water. Most have coral reefs around and are thickly
vegetated. The shorelines of some continental islands
have white sandy beaches and others are bordered by
uangroves. The islands of the Whitsunday Group are
among these continental islands.
The waters of the Great Barrier Reef were
declared the Marine Park in 1975, helping to maintain
and conserve a unique and particxdarly beautiful
natural wonder. The Marine Park Authority limits
human Activity on the reef and allocates areas for a
specific range of activities. This careful management
