An Overview of the Causes and Effects of Overfishing

Overfishing is one of the biggest threats to the environment today. While fishing may be harmless, problems arise when humans do it at a rate that outpaces the natural replacement of the fish population. Contrary to popular belief, ocean life is not an inexhaustible resource, and overfishing is a problem that affects all bodies of water – oceans, ponds, or lakes. According to the UN’s Food and Agriculture Organization, more than 70 percent of fisheries in the world are either fully or over-exploited.

In the past 50 years, the number of overfished stocks worldwide has tripled. This phenomenon poses many adverse effects on the environment, one of which is the disruption of the food chain. When keystone species like sharks are overfished, it affects the population of other species and disrupts the balance in marine ecosystems. Also, when the fish population that feeds on algae declines, it causes algae to grow unchecked, threatening the survival of coral reefs. Herbivorous fish are necessary to keep the coral clean and healthy.

Overfishing also affects the survival of endangered species and threatens biodiversity. Constantly fishing particular specie of fish can put such species at risk of extinction. Many large-scale fishing activities also contribute largely to marine pollution, especially due to oil and chemical spills. These can have devastating consequences on the environment. Regions that economically rely on fishing jobs and fish as a protein source also face major risks.

Several factors enable the problem of overfishing. One of these is the economic and food needs. Human demand for food has significantly increased along with the population. The World Wide Fund revealed that about 3 billion people globally depend on wild-caught and farmed seafood as a primary protein source. Thus, due to the market demand coupled with economic aspirations, the fishing industry is catching more fish than the oceans can naturally replace.

Many fishing methods also contribute to overfishing and endanger marine life. Using certain fishing gear like nets to catch fish often leads to the problem of bycatch, which is a large contributor to the problem of overfishing. Bycatch refers to the incidental capture of non-target marine species. These animals are trapped in fisher’s gear and tossed back into the water or killed. Animals like sea birds, marine turtles, and invertebrates are usually most affected by bycatch. Unfortunately, bycatch occurs so often that it threatens millions of sea animals annually. In some fisheries, the percentage of bycatch outweighs that of the target catch.

Unfortunately, poor management in the fisheries industry allows problems of overfishing to thrive. Fishing areas are largely unprotected and open to fishing fleets. Thus, thousands of commercial fishing vehicles ply the oceans with limited regulatory systems to protect ocean life. Illegal fishing is also rampant and a huge contributor to adverse ocean impacts. According to the World Wide Fund, illegal fishing makes up about 20 percent of the world’s catch.

Government subsidies further worsen this problem. By providing financial support to the fishing industry, the massive operations that contribute to overfishing heighten. Subsidies reduce the cost of doing business and lead to the overcapacity of fishing vessels, making operations much bigger than necessary.

Rachmaninoff’s Most Famous Pieces

Sergei Vasilyevich Rachmaninoff is one of the most famous Russian pianists and conductors. He lived from April 1, 1873, to March 28, 1943. His works are defined by sweeping melodies, virtuoso pianism, and opulent orchestration. Rachmaninov’s skill was influenced by his music education, which began with his mother, preparing him primarily for the role of a professional classical pianist.

However, his display of extraordinary talent as a young composer, as evidenced by the C Sharp Minor Prelude and the one-act opera Aleko, which he wrote while still in his youth, proved he had a future brighter than that of an average professional pianist.

His style and level of skill are said to have been influenced by composers like Rimsky-Korsakov and astounded his mentor, Pyotr Ilyich Tchaikovsky, one of the best composers of the time. As a result, the majority of his works are in a later Romantic genre similar to Pyotr Ilyich Tchaikovsky. At the same time, a few of his works have clear traces of Francois Chopin and Franz Liszt.

During his career Rachmaninoff composed 45 pieces, including 39 opus-numbered pieces, which he wrote while in Russia. He wrote the remaining six during his stay in the United States. His pieces are considered some of the best examples of the Romantic composing style to come out of Russia.

One example is Fantasy Pieces, Opus 3 – No. 2 Prelude in C sharp minor. Rachmaninoff wrote this piece while on a summer vacation at his aunt’s house in Ivanovka. He was inspired to create several of his most well-known works in this house, including his Prelude No. 2 in C sharp minor.

This composition, one of Rachmaninoff’s first, was written when he was 19. The song was derived from or taken from the composer’s 1892 collection of five solo piano compositions, Five Fantasy Pieces, Opus 3.

Much has been written regarding this piece’s complexity. For example, pianists who have attempted to perform this piece claim that while its slow tempo may make it appear simple, the chordal theme calls for endurance, solid technique, and the correct hand posture to strike all the notes in the chords simultaneously.

Another standout composition is 14 Romances, Opus 34 – No. 14 Vocalise, which is the last of his 14 Romances, Opus 34. It was written in 1912 and released in 1915 when the World War I was at its worst and his friend, the composer Alexander Scriabin, had just passed away.

This piece contains no words, so it may be sung using only a single vowel sound. It was initially composed for a soprano or tenor vocal with a piano background.

This composition expresses enormous delight and profound despair in a very evocative way. Critics and music experts identify it as solemn, almost religious music.

Another of his great pieces is Rhapsody on a theme by Paganini, Opus 43, which was composed in 1934. The debut of this piece took place in Maryland in the same year, with Rachmaninoff performing the solo piano part. This piece was inspired by a series of well-known versions of Niccol Paganini’s Caprice No. 24 for solo violin.

After completing four piano concerti, Rachmaninoff started a new symphonic orchestra composition in 1934 that had 24 variants on the well-known violin tune of Niccolo Paganini. The endeavor was challenging because the topic had previously been exploited by several other musicians, most prominently Franz Liszt and Johannes Brahms. Although Rachmaninoff’s composition only has one movement instead of the customary three, it nonetheless adheres to the standard concerto pace structure, starting and finishing quickly with a slower middle part.

The Differences between Acoustic and Digital Pianos

Pianos have existed and been evolving for about 300 years. The first piano was created by Bartolomeo Cristofori, an Italian inventor. With today’s technology there are now digital pianos, which are extremely similar to an acoustic piano except that they require electricity to function.

A fundamental difference between an acoustic and digital piano is in their action. The Italian inventor Cristofori was responsible for the invention of the very first acoustic piano action, and these actions have been in continuous development for the past three centuries. The basic function of a piano action is to convert the simple lever of a fulcrum into a striking motion for the string, which is similar to a hammer going up and coming back down. One of the attributes of the acoustic piano is the difference in tone and volume gotten when a player strikes a key. The intensity of the strike on the string could be hard or soft, depending on how the player hits the key. By applying different amounts of pressure on the keys, the player can create different tones and vary the volume. These nuances are achieved due to the mechanical link to the acoustic piano that the player has by pressing the keys.

On the other hand, digital piano actions try to recreate these subtle variations by simulating the swinging motion of the key. When the keys are pressed on a digital piano, there is a counterweight that swings up to achieve the effect. At this point, a sensor picks up the motion and determines if the key was pressed softly or firmly, and translates this into a corresponding volume. This technology, while it does provide substantial variation, does not provide quite the subtle expression of tone that an acoustic piano can.

Since acoustic pianos employ the use of strings and digital pianos do not, they require routine maintenance and should be tuned at least once or twice annually. It is quite important to employ the services of a piano tuner because it is extremely difficult for a nonprofessional to tune a piano, unlike other instruments. Digital pianos, on the other hand, do not require tuning and therefore require little if any maintenance.

Another clear distinction between acoustic and digital pianos is the quality of the sound they produce. Acoustic pianos can produce beautiful organic sounds that are very difficult for even the most expensive digital pianos to produce. If the choice of the player is classical music and they are quite serious about their music, it would be best to use an acoustic piano. However, digital pianos sometimes have an advantage over acoustic pianos due to their consistency in delivering the same sound in a variety of environments. Acoustic pianos are at a drawback here, as they need regular tuning and are subject to external factors like changes in temperature and humidity.

All acoustic pianos are large, and even upright acoustic pianos requires a lot of space. In contrast, digital pianos can easily be moved around by just one person, which of course makes it easy for performing artists to play at different venues.

Overfishing – Risks and Solutions

More than 2 billion people rely on seafood as a source of dietary protein. Without proper management, fishing threatens the ocean’s ecosystem through massive hauls that devastate fish populations. Overfishing not only endangers ocean biodiversity, but also jeopardizes the stability of the seafood industry, leading to a potential food crisis.

Overfishing is not a modern phenomenon. The fishing industry in the early 19th century destroyed the local whale population near Cape Cod in pursuit of whale blubber. In addition, the onset of the industrializing led to the rise of fishing operations that harvested more than 90 million tons of fish by 1989. A 2003 report states that industrial fishing depleted more than 85 percent of large ocean fish.

With this drop in fish populations, commercial fleets began fishing deeper in the ocean to locate and catch fish. This phenomenon is known as fishing down and destabilizes the natural balance of marine ecosystems.

Cruel fishing practices such as trawling also threaten the livelihood of countless sea animals that are unintentionally trapped in fishing nets as bycatch. In addition to catching target fish, trawlers end up hurting other species ranging from coral reef to dolphins and sharks, 30-40 percent of which end up completely wasted. Commercial fishing also contributes to habitat destruction, exacerbating ecosystem imbalances.

As one might expect, overfishing is unsustainable, and the fishing industry is now struggling to meet worldwide demands. Without fish to catch, fishing companies go out of business and countless fishermen suffer from unemployment. Data analysis indicates that overfishing practices may lead to the collapse of all fisheries on a global scale by 2048.

Today, governments around the world are designing and implementing fishing regulations to prevent overfishing and restore fish stocks. The main goal is to modify fishery management through sustainable practices.

For example, America’s top fishing port has installed sensors on boats that detect the temperature, salinity, and oxygenation of ocean water. Fishermen use this information to identify target fish populations while avoiding bycatch. Fishing regulations also guard the interests of fishermen and secure the long-term success of fisheries, thereby promoting a better future for humans and fish alike.

Policy reform has led to the establishment of annual catch limits, which help reduce overfishing. Over the past 20 years, dozens of species that were once overfished have repopulated marine ecosystems sufficiently and are now fished at sustainable levels.

The Environmental Defense Fund (EDF) actively works with the fishing industry to reform management systems. The fund has collaborated with fishing outfits in the Gulf of Mexico and their impact can be seen in the rising numbers of various marine species, including red snapper.

Surveillance systems can also help monitor fishing activities and ensure fishing outfits comply with catch limits. The World Wildlife Fund (WWF) supports the use of camera systems aboard fishing vessels for the purposes of data collection and compliance evaluation.

Nonprofit organizations also play an important role in keeping fishing operations in check. Global Fishing Watch is a nonprofit dedicated to monitoring fishing activity around the globe through open-access video monitoring. Their collected data has been used to identify illegal fishing operations and arrest the involved captains and crews.
