But here some qualities that sharks do to help our planet. In fact Sharks keep the ocean food chain in check. They do this when sharks eat seals and it keeps the seal population normal, but if there were no sharks the seal would overtake fish and squid population until they would just go extinct. Another thing sharks do to help our planet is they hold cures for human diseases. They have special characteristics that could be turned into ingredients to help find cures.
The definition of over fishing is to deplete the number of fish in a body of water by too much fishing. Overfishing is very harmful to the ecosystem, taking a species close to extinction or completely extinct. As a species gets close to extinction it can be very hard to restore them back to sustainability. Even closing the fishing game for that species is not enough for a species to comeback from overfishing. Both recreational and commercial fishing have a huge impact on overfishing, by keeping under sized fish and other aquatic life.
If you desire to remain safe from shark attacks, you have to comprehend them a bit more deeply than most people do. These ideas from ichthyologists (or shark specialists) should assist you stay safe. Sharks in fact hate eating individuals Sharks have actually evolved over millions of years to consume seals, fish, crabs, turtles and other marine life. In general, they don't seem to have a taste for land animals, particularly humans. Sharks that take a bite from human beings typically spit the expand.
People shouldn’t kill or disturb Loggerhead Turtles. We should save all the Loggerhead Turtles in the world and then we can have them as pets. One main reason for Loggerhead Turtle death is because of fishermen nets. We can save them by going Scuba diving. We can also save Loggerhead Turtles from reckless drivers by Scuba diving because of the debris.
When an animal eats plastic, it causes their minds to believe that they are full but plastic does not give them the nutrients that they need and will cause them to starve. The last well known pollutant is oil. “When oil comes in contact with animals, it can coat the surface of their bodies with a sticky film that can irritate and even suffocate them” (Wroble 44). This is a dangerous threat to animals because in most cases oil can kill them. “Crude oil called
I think Killer Whales should not be in captivity because, of the injures they can get in their tanks, how they get stressed out and they are better in the wild. The first reason why I think should not be in captivity is of what happens in their tank. The first piece of evidence from the PETA practical “Aquariums and Marine Parks” is that since the tanks for the orcas are usually small for them, they get insane because of the echolocation they use. This makes me think that since their fin sometimes curves, that they would get injured while swimming. In addition, this might make the whale die faster than what they are supposed to live to.
Sharks are much more useful when kept alive, and can be beneficial for several years; however, once they are dead there are no more benefits to be reaped besides what is originally obtained. The decrease in sharks can also be detrimental to many fisheries. Sharks feed on other carnivores down the food chain. Carnivores that sharks prey on often prey on creatures such as shellfish. Without sharks, there would be an increase in several other carnivores, leading to a vast decrease in the amount of shellfish and other herbivores in the sea, which can be detrimental to local fisheries.
Dispersants cause the oil to break up into smaller droplets, which become miscible in water. However, these dispersants may result in more ecological harm than good. The chemicals contain nonbiodegradable toxins that can kill fish and migrate great distances. Dispersants also are blamed for the massive oil plumes several hundreds of feet underwater, harmful to all aquatic life, especially fish larvae and filter feeders. Moreover, because of the large volume of oil that has been spilled, the amount of dispersant required and the amount of oil dispersed simply suppresses the problem, rather than solving
How the oceans may die is crucial to understand in order for them to be preserved for the survival of the planet. Numerous human activities generate a staggering amount of grave complications for the oceans and its crucial marine life. One of the most direct human activities that causes rapid decline in marine populations is overfishing. Some of the species
Thirdly, the ocean and its inhabitants are greatly affected by marine pollution. Marine pollution is the entrance of hazardous materials into the ocean. The ocean can be polluted a number of ways, including garbage, sewage, and noise. Garbage pollutes the ocean by disturbing marine life and tarnishing the marine environment, it can also damage ships. Sewage pollutes by adding dangerous chemicals to the ocean and depleting oxygen used by the animals.
As humans expand they are producing more waste and need a place for it to go. In some countries, people just pump the waste into the water, as a result it is harming the manatees. The waste that humans are pumping into the ocean is causing toxic algae which the manatee eats and it makes the sick or could kill them. The waste from humans hurts the manatee also by
