What is killing our reefs?

I happen to be one of those conservatives who believes global warming (or climate change, as it is now more accurately called), is real and caused in part by man. That said, global warming is also partly a natural phenomenon. Some experts suggest man’s contribution to the changes in climate are just 1 percent to 2 percent. Global warming skeptics suggest the impact is practically negligible and that efforts to slow it are unnecessary given the economic and regulatory burdens those efforts create.

Earlier this month, my wife Amy and I took a trip to St. John, U.S. Virgin Islands, for a week of rest and relaxation. It was our fourth visit to St. John in the past 12 years.

St. John is unique, as it is mostly preserved thanks to the generosity of the Rockefeller family, which donated 5,000 acres to the U.S. government in 1956. Following subsequent purchases of land by the federal government, Virgin Islands National Park now covers 60 percent of the island.

St. John and the park are famous for its coral reefs and picturesque beaches — one of which is considered among the 10 best in the world. The park has miles of trails for hiking through mountainous tropical rainforest, and the reefs are favorites of snorkelers and scuba divers — though the latter is prohibited in most reefs within the park’s boundaries.

During our week in St. John, we visited a different beach or two each day, selecting those with the best snorkeling. September is the beginning of what is usually an active hurricane season in the Caribbean, so there are fewer tourists, many restaurants and tourist-related businesses are closed and the normally packed streets of Cruz Bay, the largest town in St. John, are nearly bare.

The trade-off of having to potentially dodge hurricanes is an acceptable one when you consider you can go to the most popular of St. John’s beaches, Trunk Bay in the park, and share it with no more than a half-dozen people on most any day there isn’t a cruise ship in port at nearby St. Thomas.

Although much of St. John will never be developed because of the national park, that doesn’t mean St. John’s ecosystem is being adequately preserved and protected — directly or indirectly.

The first time we went to St. John a dozen years ago, we snorkeled at Trunk Bay and were dazzled by the plethora of fish, sea turtles and vibrant colored corals just 75 or so yards off its sandy beaches. Every time we have been back since that first visit, we have noticed the corals are in decline, and the overall health of the reef appears worse.

Unfortunately, other reefs we snorkeled looked to be in similar deteriorating condition.

The obvious question is: What is the cause of the rapid deterioration of St. John’s coral reefs?

Some suggest that Continue reading “What is killing our reefs?”
