The Great Barrier Reef is the world's largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over 2,300 kilometres (1,400 mi) over an area of approximately 344,400 square kilometres (133,000 sq mi). The reef is located in the Coral Sea, off the coast of Queensland, Australia. The Great Barrier Reef can be seen from outer space and is the world's biggest single structure made by living organisms. This reef structure is composed of and built by billions of tiny organisms, known as coral polyps. It supports a wide diversity of life and was selected as a World Heritage Site in 1981. CNN labelled it one of the seven natural wonders of the world.
The Great Barrier Reef is facing a number of threats, including climate change, pollution, and overfishing. Climate change is the most serious threat, as it is causing the water temperature to rise, which is causing the coral to bleach and die. Pollution from agricultural runoff, coastal development, and shipping is also a major threat. Overfishing is also a problem, as it is reducing the population of fish that help to keep the reef healthy.
The Australian government is taking a number of steps to protect the Great Barrier Reef, including reducing greenhouse gas emissions, improving water quality, and managing fishing. However, more needs to be done to protect this natural wonder.

The Great Wall of China is one of the most famous landmarks in the world. It is a series of fortifications that were built across the historical northern borders of ancient Chinese states and Imperial China as protection against various nomadic groups from the Eurasian Steppe. Several walls were built from as early as the 7th century BC, with selective stretches later joined by Qin Shi Huang (220–206 BC), the first emperor of China. Little of the Qin wall remains. Later on, many successive dynasties built and maintained multiple stretches of border walls.
The defensive lines contain multiple stretches of ramparts, trenches and ditches, as well as individual fortresses.
