Tourism Industry: A Threat to the Marine Ecosystem

0

By: Talat Mohsin

India is home to a large number of spectacular marine life which have a habitat in its tropical oceans along with the usual hill stations and various wildlife sanctuaries. With the ever-increasing popularity of beaches as a tourist destination in India, the marine life is now under a threat.

Due to the high demand of tourists in the coastal areas, many changes are being done to them to accommodate more and more people. Many of these activities have adverse effects on our ecosystems. While it generates income that often makes it possible to help improve our environment, the negative impacts are more than positive. Some of these are listed below:

  • Increase in water and energy consumption
  • Increase in pollution (air, water, and noise)
  • Litter, erosion, and fires
  • Disturbance in the ecosystem
  • Spoliation of flora and fauna
  • Increase in wastage
  • Disruption of the aesthetic appeal of the location

An example of this is the coast of Sindhudurg. In recent times, Sindhudurg has emerged as a very popular tourist destination. But the popularity has resulted in the endangerment of its marine life. Thankfully, it’s mainstreaming project has taken initiatives to increase awareness among the people and promoting biodiversity sensitive practices. Young and trained scuba divers are also taking initiatives to serve as agents of change. They perform rescue and release of animals and also get rid of the major solid pollutants in the water. They even educate people on marine conservation and it’s importance. Often, consumers don’t realize the threats looming on our marine life because of our incessant travels. But as the need for environmental sustainability is growing, more and more public and authoritarian figures are shifting their stance as well. The ecosystem is ours, therefore the responsibility of protecting it falls on our shoulders too.

Oceans will be bluer and greener in color in 2100, thanks to climate change

Climate change is not only increasing the sea level but will also change the color of the ocean by 2100. A new study by Massachusetts Institute of Technology (MIT) found the relation between color and climate change. The color won’t be extremely dramatic and hardly noticeable by the human eye but the change is real.

The warming planet is changing the distribution of phytoplankton across the world’s oceans. It’s well-known that seasonal changes regularly change colors, bit warmer oceans may permanently alter the mosaic of blues and greens as seen from space. In subtropical regions, warm waters will get even warmer, driving out phytoplankton populations and even marine life, in general. In water closer to poles, the warming will make the water appear greener while in subtropical regions, it will appear bluer.

“These microscopic organisms live in the water and are the base of the marine food chain,” said Stephanie Dutkiewicz, a marine ecologist at the Massachusetts Institute of Technology and the leader of the study, published Feb. 4 in the journal Nature Communications. “By being in the water, they change the color that we see by eye. If there are less of them in it, the water will be slightly bluer.”

Phytoplanktons are very small plants residing in the water bodies. They provide food for the fishes and other sea animals. They are the food chain initiator in the water bodies.  Scientists have found that climate change will likely alter the types of phytoplankton that abound in future oceans.

For their research, Dutkiewicz and her colleagues developed a computer model that simulated changes in the world’s climate from 1860 through 2100. The model assumed that global temperatures would rise by 3 degrees Celsius — which is what most scientists think will happen if no effort is made to curb greenhouse gas emissions. The simulations, which take about three weeks to run on a large array of computers, revealed we can expect our oceans to look a little different in the future.

Climate change is real though many of our leaders don’t want to believe it. This effect of the color change is a little trivial but the main issue is the decline in the population of phytoplankton. They initiate the marine food chain and without them, the sea animals would die. Let’s hope we save that the conservative estimation of 3 degrees Celsius rise doesn’t become the reality.
