Sand Mining

I grew up on the southeast coast of China. I stayed there for almost 18 years, and I found out my favorite ocean blue was disappearing. A lot of sand mining industries were built near the coast. They brought golden money to people's wallets, but they also brought dirty yellow into the sea. Also, fishing industries were affected by the pollution which was caused by sand mining. So, fishermen need to travel far away to reach the deep blue sea, which was more than 20 miles away from the sea. They also broke an ecosystem in there to force sea creatures to run away to the deeper and further zone of the sea. When the sand in the coast is dug out, people have to dig sand on the seabed. As a result, a negative cycle just happens again.
