The Great Barrier Reef is located off the northeastern coast of Australia. The barrier reef is the largest coral reef in the world and consequently is the largest living structure on the planet. Other types of reefs include fringing reefs and atolls.
Coral reefs are delicate ecosystems and are threatened by warming oceans brought on by present day global warming. Warming seas lead to coral bleaching; a phenomenon where corals release their symbiotic algae, turn white and die.

Answer:
Kangaroo care
Explanation:
Kangaroo care: In psychology, the term kangaroo care is defined as a method in which the parents hold a baby in a way that creates a skin-to-skin contact. In kangaroo care, the baby is supposed to be naked by only wearing a cloth piece or a diaper on the back and therefore he or she is placed in the parent's breast area holding an upright position. It was first developed during the 1970s.
In the question above, the given statement is an example of kangaroo care.
You might be surprised to find, however, that the first seismometer was invented in China in 132 AD by a Chinese astronomer, mathematician, engineer, and inventor called Zhang Heng. The instrument was said to resemble a wine jar six feet in diameter, with eight dragons positioned face down along the outside of the barrel, marking the primary compass directions. In each dragon’s mouth was a small bronze ball. Beneath the dragons sat eight bronze toads, with their broad mouths gaping to receive the balls. When the instrument sensed an incoming seismic wave, one of the balls would drop and the sound would alert observers to the earthquake, giving a rough indication of the earthquake’s direction of origin. The device is said to have been very accurate and could detect earthquakes from afar, and did not rely on shaking or movement in the location where the instrument was positioned. The first ever earthquake recorded by this seismograph was supposedly somewhere in the east. Days later, a rider from there reported this earthquake. Moreover, it had the most wicked ornaments. They don’t make scientific instruments like they used to! Of course, the insides of the seismometer was filled with a sensing mechanism of some sort, the contents of which have been lost in time. In all likelihood, a simple or inverted pendulum was employed, according to experts.
