Biodiversity Pros And Cons

Biodiversity

Biodiversity is the variety of all living organisms in a specific habitat, it is made up with abiotic and biotic factors. Biodiversity gets used to measure the health in a ecosystem. Humans have, over several years, created threats to biodiversity, one of them is overexploitation. Under the impact of biodiversity changes and overfishing by humans, many species have become extinct, which, in the end influences the biodiversity again. Many solutions have been attempted to be created over time, though there are still many pros and cons for each of them.

Biodiversity provides clean water, oxygen, medicine and the food we eat, which all are essential for the health of human beings. According to panda.org, then if the biodiversity decreases at some of the most biodiverse places on the earth, such as the Amazon, then it most likely will have negative effects on the entire planet. Biodiversity ensures a natural living form for all living organisms and it boosts a ecosystem’s productivity where each species, no matter size all have an important role. Healthy ecosystems can better overcome and recover from challenges. …show more content…

Overfishing happens because fish are captured faster than they can reproduce. With the oceans covering more than 70% of the Earth the health of the marine life is essential for the humans and many other organisms to survive. Each time a boat goes out fishing, the boat on average waste 90% of all the fish they have caught, according to ted.com, this is just one example of overfishing. This means that 90% of the fish are caught but not used for food and they are just thrown out. Wasting fish affects the biodiversity in the oceans since it puts extinction the species to risc, this affects the food

Biodiversity can also be observed on a very small scale, such as in a lake, or a tidal pool. Biodiversity is important because it provides us and the environment with a lot of important things. For example, biodiversity provides us with

Andy Dehart, Discovery Channel Shark Advisor, spoke about the North Carolina shark over fishing problem. The shark populations on the East Coast were extremely over-fished which lead to the over population of sting rays, a main food-stock for sharks. The stingrays in turn decimated the shellfish populations on the East Coast, leading to calm and shellfish shortages. This shows that sharks are necessary for every eco-system and their destruction affects us in more ways then we can imagine. Sharks are very at-risk for over-fishing because they take a long time to reach the stage where they can reproduce and in general only have a few pups when they give birth.

Sarah Freeman’s article in The Ethicalist explains the negative effects humans have on the ocean. These negative effects include plastic pollution, global warming, and worst of all, overfishing. Overfishing occurs when a fish species is wild caught faster than it can reproduce. This leads to fewer fish in the ocean, meaning less marine biodiversity (Freeman). After Freeman spends most of her article explaining how the oceans are suffering, she then starts talking about what can be done to prevent a baren sea.

Biodiversity is the variety of life in the world. Biodiversity is important everywhere because it is a resource in which all living organisms and future generation organisms depend on. It is important to California because California has many different bioregions. If California did not have biodiversity in its bioregions, one animal would have to adapt to all the different regions. By adapting, it would have to live off the land and eat its own species.

The next day, Sonia went right outside into the forest of her backyard. Salinger tailing behind, her she looked around and took it all in once more. The sun was finally out and it shone through the dew drops on the leaves. She could see the a ruby red, pastel orange, bright yellow, vibrant green, royal blue, and the perfect shade of purple in a rainbow shining through all of the dense forest. Looked up to see the sun, and she thought it was beautiful.

Invasive Species Invasive, alien species, those which colonise, expand and out compete native species (Smith & Smith, 2009), are a major threat to our habitats, terrestrial and aquatic species, and biodiversity. Agricultural and leisure industries are affected as well as conservation welfare and the continued wellbeing of man, flora and fauna. Whole ecosystems can be distorted and the economic cost of awareness, prevention and eradication systems is substantial. Most invasive species have been introduced by mandeliberately or otherwise. As an island, Ireland has been subjected to less invasive species than larger nearby land masses e.g. Europe, but islands have a less diverse species population and are therefore more vulnerable when invaded.

Imagine what would happen if we lived in a world where water was kept 8 feet off the ground and there was absolutely no way you could get it if you weren’t tall enough. Most likely, the short people would die off. The taller ones would multiply, and before long, instead of a population of people of all sizes, you would have a population of only tall people. Living things that are best suited, or adapted, to their environment survive and multiply. Those that are not, are unable to survive.

About 71 percent of our planet Earth is covered by water, and the majority comes from the oceans (about 96.5 percent of all Earth’s water). It remains as the most expansive, diverse, and mysterious places on planet Earth. But it is being threatened by the pollution by people and nature itself. By polluting the habitat of marine organism will indirectly affect the ecosystem of the marine life. Marine life is dying and as the result the oceanic ecosystem is threatened.

DNA in Forensic Science DNA is the carrier of genetic information in humans and other living organisms. It has become a very useful tool in forensic science since it was discovered. In forensic science, DNA testing is used to compare the genetic structure of two individuals to establish whether there is a genetic relationship between them. One example of the use of DNA in forensic science that is important in biology today is comparing a suspect’s DNA profile to DNA that was discovered at a crime scene.

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. Not only do fish have to worry about fishermen but they also have to worry about each other, fish deplete their own population by feeding on one another. For example, Betta fish are known to eat fish of the same species but can live peacefully with fish of another species.

Fishermen throwing their garbage into the ocean, which affects the health of the coral and the fish that live in it. Climate change is destroying the living environments of various animals, like the walruses. The WWF1 started their campaign Seastars to fight against the threats of the ocean. Overfishing comes down to one thing: Catching too much fish which leads to a degradation

Hence, overfishing threatens coastal nations down to the local level, devastating communities whose dominant sources of labor and revenue hinges on healthy, plentiful stocks of fish. Also, marine life imbalance may affect the targeted fishing of top predators such as billfish, sharks and tuna that eventually disturbs marine communities. In fact, it is causing increased abundance of smaller marine animals at the bottom of the food chain. This in turn has impacts on the rest of the marine ecosystem, such as the increased growth of algae and threats to coral reef health.

Wildlife Conservation is often seen as a bad thing, but if you look at it from my perspective, then it is actually a good thing. People think of it as holding wild animals captive, but we are actually protecting them from poachers. The purpose of Wildlife Conservation is to protect the animals in danger, which I am in agreement 110%. Other people argue that we shouldn’t have conservations, but they don’t know the harm that can happen to unprotected animals.

Zoos have been around since the eighteenth century. A zoo is defined as a compound where wild animals are kept for viewing and studying. The purpose of a zoo is mainly for education and protection, preserving animal species that are either at a risk of becoming extinct or for increased collection size (Jamieson). Animals from around the world have been enclosed in an area where we can admire and study these fine creatures. However, many modern zoos around the world have introduced animal shows, petting and feeding sessions to attract more visitors in order to earn more money.
