Coral reefs are a very important component of the ocean’s ecosystem because they support sea life, such as crabs and sea turtles. in fact, over four thousand species depend on the survival of the reefs, which are being destroyed by bleaching. more must be done immediately to save the reefs.
development along the coastal regions has significant negative effects on coral reefs. the reefs are an essential part of the ocean’s ecosystem, and when people build structures on top of them, they are easily damaged because they are so fragile.

Explanation:
Humans use the Earth's natural resources for a number of purposes, including: energy and fuels for warmth. building materials for shelter. fuels for transport. Earth is the home planet, right for life. But rights, a notable political category, is, unfortunately, a biologically awkward word. Humans, nonetheless, have rights to a natural environment with integrity. Humans have responsibilities to respect values in fauna and flora. Appropriate survival units include species populations and ecosystems. Increasingly the ultimate survival unit isgloba l; and humans have a responsibility to the planet Earth. Human political systems are not well suited to protect life atglobal ranges. National boundaries ignore important ecologicalprocesses ; national policies do not favor an equitable distribution of sustainable resources. But there are signs of hope.
<span>It must measure the supergranules. This refers to the physical pattern casing the exterior of the quiet Sun with an archetypal horizontal scale of approximately 30,000 km and a lifetime of around 1.8 d. Its most noticeable or visible signature is as a fluctuating velocity field of 360 m st-1 rms whose components are mostly horizontal. This was exposed more than fifty years ago, conversely clearing up why and how it originates still represents one of the core challenges of modern solar physics.</span>
