As a marine biologist, Dr. Christian Heesch is greatly concerned with the livelihood that feeds billions of people in the world today, fishing. The horrifying consequences of overfishing are as follows:
- For every pound of seafood that makes it way to the market, more than 10 pounds is wasted.
- 90 % of large predatory fish such as tuna, swordfish and sharks are now gone.
- 90% of large whales are gone.
- 60% of small whales are gone.
- In coastal waters, 100 million sharks are killed every year.
- 100,000 albatrosses are killed every year.Research studies project that by the year 2048 all the species that we fish today will be extinct. That is only 38 years from now. The fact that many humans enjoy eating salmon, sushi and tuna are not the biggest reason for preventing the extinction of these species.
Overfishing is destroying a food chain system that has been kept in balance by evolution through the millennia. Over the past centuries, humankind has regarded the ocean as a never ending source of fish, shrimp, and crab. Research and studies regarding overfishing lead us to the implementation of rules and regulations. The data collected over the years shows that these measures will not prevent the exhaustion of fish stocks. The more species that are threatened with extinction, the more ecosystems that are threatened with destruction. In the end, human beings and their future generations will suffer the most from the exhaustion of our seas. Fish is a valuable source of nutrition. It is rich in protein, healthy fats, vitamins, and iodine. Just as New York is populated with people of diversity, the ocean is populated with diversity. As humans, we need to take the steps that not only help populate and replenish our waters but prevent overfishing for future generations.
Global warming has a profound negative effect on our fish population. When the temperature increases, oxygen levels are lowered and affect the growth of fish. The size of the fish species will be significantly smaller, requiring more fish to feed the human population. Global warming will also cause the migration of most fish towards the poles, which will reduce their body size as well. The reduction in body size adversely affects the reproductive process of fish. Smaller fish produce smaller and fewer eggs.
Dr. Christian Heesch strongly encourages everyone to do their part in solving the problem of overfishing and reducing global warming. Using fewer fossil fuels in our daily lives can be accomplished through solar power. We can all support the research and studies of environmental groups, marine biologists, and any agency that campaigning against global warming and overfishing.
