Our daily activities can have a devastating impact on these fragile ecosystems. Sewage, fertilizers, and industrial chemicals seep into our waterways, poisoning the water corals call home.

Coastal development is another sneaky threat to reefs. As human populations grow, so does the demand for beachfront property. But when we pave over coastal areas, it alters water flow and sediment patterns, smothering corals and disrupting their delicate balance.

These threats are like a slow-motion poison, gradually eroding the health and beauty of coral reefs. Bleaching, a process where corals expel their symbiotic algae in response to stress, is a common symptom of pollution and coastal development. Without these tiny algae, corals lose their vibrant colors and become more vulnerable to disease.

In the case of the Great Barrier Reef, Australia’s iconic underwater treasure, pollution and coastal development have contributed to a decline in coral cover of over 50% in the past few decades. It’s a sobering reminder that our actions can have far-reaching consequences for these precious ecosystems.
