Top 6 threats to marine biodiversity - (2023)

Even if it is claimed that humans are the most intelligent living beings on Earth, they will face extinction if there are no other species to support them to live. The diversity among us must not be erased and we have to protect it and it will protect us just the same.

Floods that occur during the rainy season are caused by man throwing rubbish everywhere, they also cut down many trees for their own benefit. Your act of not protecting nature is retribution from nature, which is bad retribution. When humans don't care about how to save our dying earth, they ignore theglobal warming in the oceanand land. And if the ice at the pole is melting, there is a chance that all things on earth, including skyscrapers and even the island, will drown as a result of our ignorance. So for those of you who still care about our dying land, especially our diversity of marine life, I'd like to make you aware of the threats to marine biodiversity.

1. Exploitation

(Video) Top 20 Deep Sea Mysteries That Will Freak You Out

Exploitation is any human act of taking too much of natural resources. Exploitation can also be defined as the act of humans taking large numbers of the population, where the population itself cannot replace the number that has been taken by humans. It's like a human taking five out of six fish stocks. The time it takes for the fish to recover and reach number six is ​​longer than the time it takes for humans to exploit the fish.

When this kind of act continues continuously, surely all living things in the sea will become extinct and humans will have no more fish supply. Exploration also came from the coral reef. Coral reefs are being taken over by humans to be sold as aquarium decorations. Don't you know that the coral reef has the function of breaking the waves so that the waves you feel on the beach are not too strong? When the number of coral reefs is dwindling, the beach will no longer be a fun recreation spot.

2. Pollution

Technology is made to help make human work easier and faster. The very existence of technology brings us not only a positive but also a negative impact. Taking technology in the area of ​​transport as an example, such as cars, motorcycles and ships. These transports use fossil fuels that produce waste emissions that can pollute our earth. Ships sailing the sea can produce waste emissions that can pollute air and seawater. Any bird that flies over the sea will inhale polluted air that can damage its respiratory system and lead to death.

The same will happen with marine mammals that tend to rise to the surface of sea water to breathe. Even fish at the bottom of the sea also need oxygen by sucking in seawater, and if the air is polluted, surely all fish at the bottom of the sea will die. Oil that falls from the ship into the sea also makes it worse. As the oil is made for the machine and not for the body of living beings, there are some chemicals inside it that can cause the death of living beings.

3. Loss of habitat

Habitat loss is the next threat to marine biodiversity. Fishermen will do everything to catch their prey as much as they can. They may use various forms of fishing such as the use of trawls, bombs and drugs. The use of bombs not only leads to the death of fish, but also severely damages the coral reef. The coral reef has become a place where many fish trust their lives. Some species of fish not only live inside corals, but also feed on coral reefs.

There is also another case of a citizen who illegally sold sea sand to another country. They use certain technology to suck the sand and without realizing it they can also suck some aquatic animal that lives in the sand that is usually buried with the sand of the sea. During delivery to the other country, this aquatic animal may die. And even if they survive, they may not live very long because they cannot adapt to their new environment. The suction of sand from the sea can also destroy the place where the coral reef lives.

4. Species invasion

I know that there are some people who try to protect marine biodiversity. But sometimes their lack of knowledge can become another threat to marine biodiversity. When some people are trying to breed certain species of marine animals, they usually let the species go into the wild in hopes that they can survive and create more babies to prevent the extinction of certain species. The moment humans release the species they create could become a threat to marine biodiversity.

Thus, they usually release marine animals only on the beach or sea closest to their conservation location. This act will be acceptable when the conservation site is located in the native habitat of the marine animals they care for. Otherwise, people who release the marine animal they care for could disrupt the food chain at sea. Taking a simple example, you want to release ten sharks into a sea that is not the shark's own native habitat. The shark you released will slowly eat more fish that are below them in the food chain. When there are more carnivores than herbivores, of course, both animals will die due to high numbers of predators and lack of food.

5. Climate Change

Basically, our earth's climate changes because the age of the earth itself is aging. But the existence of emissions from vehicles and factories is making climate change happen more quickly. The smoke produced by the vehicle and factory will be released into the atmosphere and trapped there, as the smoke contains toxic chemicals such as carbon dioxide and monoxide that cause the greenhouse effect. The greenhouse effect can cause global warming that can cause many negative effects for all living beings. Taking the ice at the pole as an example, global warming could cause the ice to melt and the world to drown.

Another example is the growing number of living beings from the water of death. Molluscs and crustaceans are two of the many aquatic living things that are so sensitive to changes in temperature that they can die more quickly compared to other aquatic living things. When crustaceans and molluscs that have become prey to other aquatic animals die, the food chain above them will certainly be disrupted and could lead to extinction.

Basically, all threats come from ourselves, so make sure you keep everything in balance and don't become a greedy person. These are all major threats to marine biodiversity that have become not only threats to marine biodiversity, but also to humans. I hope this article inspires you to do more and save more living things and keep the ecosystem in balance. Thank you for reading this article to the end, which means you really care about our marine biodiversity. Don't forget to keep reading and updating deep ocean news with us.
