Discoloration of corals is explained as a state of stressful occurrence at coral reefs. Coral bleaching means destroying the relationship between coral and unicellular algae. The most common symptom of whitening is that the corals become whitish completely. The reason for whitening the corals is because corals release algae (yellow algae) that inhabit the tissues as the water warms up. When coral is bleached, it will not die at first and can survive even under bleaching conditions.
Many scientific studies record the direct causal effect of human behavior on coral reef systems. However, few people know how to step back and influence the existence of human beings on the natural functions of the whole coral reef system. What we do not understand is the impact of environmental factors on coral reefs without people. It is speculated that there is certain physical driving force as to how the healthy coral reef community grows. What natural physical conditions will bring healthy coral reefs in an unaffected environment? What are the natural biophysical relationships in these ecosystems?
The coral reef ecosystem of the world is threatened by human disturbance and climate change. As a result, many scientists began to study the ecosystem of coral reefs worldwide to better understand the causes and effects of coral reef damage. Hodgson (1999) and Carpenter et al. (2008), they know the ongoing degradation of the worldwide coral reef ecosystem. - Motivation is a very broad term being discussed in various contexts. Business environment, performance dynamics in competitive fields, motivation for friends and family, and motivation to achieve goals.
