Some biodiversity threats that affect both marine and terrestrial ecosystems would be climate change and introducing new animals into unfamiliar habitats. Introducing these new animals to one of these ecosystems could cause many problems and affect the competition between animals, change the predation rate, and introduce new or deadly diseases to the local animals. Climate change is very influential on biodiversity as it can force animals to move to different areas and not know the proper time to breed. This can cause some competition among the animals that are moving to an area and the animals that were living in that area previously. A problem that only marine ecosystems have would be seafloor destruction as destroying the seafloor would mean that marine wildlife will have less of an ecosystem to roam in.
On the other hand, species extinction will influence many part of the natural environment. In the article “Consequences of changing biodiversity” by Chapin et al. (1886) said that the result of altered diversity can be affect on richness, evenness, and composition, all of those things need to be focus because they can respond the huge influence to ecosystem. Also the abundance of species can be consequence of ecosystem function and progress (para.7-14). The nature’s function and progress can be broken by species extinction which means human should keep focus on this
Procedure is "unnatural": Transgenesis is unnatural in the sense that the insertion of DNA material in target animals would not take place without human intervention. Undesirable Properties Could Appear: The possibility that undesirable properties could develop is a real risk. Transgenic fish could produce new or modified proteins that, while neutral or beneficial to the fish, could be toxic to humans. What about Escapes? The impacts of escapes are of substantial concern .Fundamental issue associated with escapes of transgenic fish is their potential to become an invasive, “exotic” species in an ecosystem which may challenge the wild relatives.
Fish for Small Unheated Aquariums and Goldfish Bowls Filed under: Aquarium Fish Tanks andFish Tank Design andFreshwater Tropical Fish Certain fishes are often kept in bowls or small plastic aquariums that lack heating and filtration equipment. The fish most often kept in this way include goldfish, bettas, white cloud mountain minnows, and danios. Each of these fishes have different pros and cons when it comes to keeping them in this fashion. Goldfish, Carassius auratus: Superb in Large Unheated Aquariums Goldfish grow. Common goldfish can grow up to approximately 12 inches in length which is larger than some of the containers the juveniles are kept in.
The Shubunkin goldfish have been developed from mutations in telescope eye goldfish (Demekins) back in 1900 in Japan. Diet: Omnivore. In the wild, they feed on a wide range of food including plants, small crustaceans, insects, and detritus. In captivity, they will accept most aquarium food including pellets, flakes, and live prey such as worms. Additional information: The Shubunkin, also known as the “Poor Mans Koi” or Chu-wen-chin in China is a type of single-tailed goldfish with calico colors: a combination of orange, white, black, red, and blue markings.
These mussels attach to hard surfaces such as rocks or boats. They were first introduced to the Great lakes in 1988 but were originally from Russian and Ukraine lakes. The Zebra Mussels were first found in Lake St. Claire (one of the 5 great lakes) which within one year they rapidly spread to almost all of the Great Lakes except Lake Superior. This is because Lake Superior is not the ideal
Food is one of the reasons behind human’s survival on this earth. As our universe goes through various developments, our food is also getting effected by those highly effective changes, that it goes through many preservative to make it last as long as possible in our shelves. Which lead us to get used to the idea of preservatives, plus manufactures promote it in advertisements and make us consumers believe that processed food is harmless. However, processed food can cause lethal diseases, obesity, and psychological problems. Opponents of preserved food argued that processed food chemicals maybe one of the causes for dangerous lethal diseases.
INTRODUCTION 1.1 Background of Study Pesticide that based on chemical is harmful to the user and the environment. Even though the pesticides are sprayed on land, they can make their way into a water source, such as a river, ocean, or pond. If a body of water becomes contaminated with the chemicals, many fish and other animals may die and get sick. This can throw the whole ecosystem off balance. Another way pesticides can spread and cause potential harm is by volatilization.
Humans are impacting the world’s biodiversity in many negative ways, by the things that they do to get what they want and all at the loss of the natural environment. If humans carry on the way that are soon nothing will be left on this earth which is extremely sad to think about. Making small changes could really make a big impact. Over harvesting has possibly got the greatest effect on biodiversity and the environment. Removal of an organism from its environment can often leave irreversible impacts on the environment its self.
EFFECTS OF WATER POLLUTION. There are numerous effects of water pollution. Some of these effects can be recognized immediately, whereas others are not recognized immediately, thus may show up for months or years. Some of these effects of water pollution include: The damage in food chain. When the water is toxicated, the toxins will move from the water to animals who drinks the water and when humans also eat the meat of these animals the toxic is transferred to them which is definitely going to cause damage.
