Coral reefs are dying at an alarming rate thanks to many factors, mostly caused by humans. For instance, when we pollute the earth and our oceans by burning greenhouse gases, we cause climate change. This affects the coral as they can’t withstand the water raising by only a few degrees. This often causes coral bleaching, which kills these animals. Also, storms can destroy reefs, also often caused by humans affecting the environment.
In the article, “Fighting for Foxes” the authors, Conover and Curry, explain how the Channel Island Foxes were close to extinction and how the population arose and came back. The process of how the Channel Island Foxes almost became extinct is this. The Bald Eagles started to decline because DEE, a chemical got into the food web, causing eggs to break easily or not hatch at all. The Golden Eagles then started taking over the area. The reason for this is because Bald Eagles started declining and left no competition for Goldens.
The act of hunting whales has been around since the beginning of human history. However, overexploitation throughout the last centuries has severely depleted these species. Yet still, thousands of whales are killed each year for profit. Mankind’s avaricious nature for more money has driven these creatures to their demise. Despite that, an increasing number of people worldwide are against commercial whaling.
However, mercury evidently was lost during the mining process, and ended up either flowing to the downstream environments, leaking into underground soil or bedrock. Small mercury particles were often floating on the top of the water for miles past the mining sight. Mercury was the quick fix that settlers were looking for. However, this quick fix caused a life-time of destruction, mercury found its way not only contaminating the water supply and soil but through the food chain. More often found on the wildlife and vegetation, especially in the tissues of fish in the rivers, thus causing serious health issues to humans eating high amounts of fish.
Natural disasters such as earthquakes and tsunamis can have a devastating effect on the coral in that area. The 2004 tsunami in south East Asia completely obliterated everything in its path, destroyed hundreds of ancient coral reefs (anthozoa) in these tropical waters. Many species of coral, such as the stag horn coral; a hard species of coral that branches out to look like deer antlers, are today classed as an endangered species due to the severe decrease in the corals range. How viable are the artificial coral reefs (anthozoa) in replacing the natural reef environment? What are its advantages and disadvantages?
Red Tides affect the marine and land life in various ways, the most important of which are listed below 1. Effects on human life: i. Paralytic Shellfish Poisoning (PSP): This happens if fish contaminated with Alexandrium species is consumed. It majorly affects the nervous system and in many cases leads to paralysis. In extreme cases, the paralyses may affect the respiratory system and ay result in death. ii.
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
The consumption of these plastics can affect the entire food chain, poisoning the jellyfish who eat them, the fish who prey upon them, their prey, and so on. For example, the Midway Atoll, an atoll in the North Pacific Ocean, receives 20 tons of the Patch’s trash annually, and because of this the majority of the Albatross sea birds that inhabit the atoll have plastic in their digestive system, which causes around ⅓ of their chicks to die,
In the United States alone, more than one million animals die every year from chemical, drug, or cosmetic testing. Is our vanity really worth the inhumane suffering of millions of animals around world? Just like my photo of monkeys being restrained and forced to participate in unjust testing? Animal testing in cosmetics should be discontinued because animals ' lives are being wasted, animals will not always have the same reactions as humans, and there are so many other alternatives that are more beneficial than testing on animals. However, there is an abundance of animal testing happening today that only leads to the high demand of animal lives.
(Ed). Animal Experimentation, San Diego: Green haven Press Inc., 2000) Some of the tests conducted on rabbits include eye irritancy tests, acute toxicity tests (LD50), and skin irritancy tests. as well as other effects but one of the main effects that sometimes is the spark of the extinction of a whole specie which is the killing of wild animals for it’s fur, as said by (Haugen, David ,2000)meat or just for joy which actually results in a huge decrease in a lot of species because they can 't reproduce new babies for that specie for example the White Lion Specie , it had large amounts of white lion but due to a lot of hunting by people on them, they are now found in south Africa but with a risk of being extinct and the panda as well and that’s because we can 't provide that animal the suitable environment neither it’s food resulting in a huge amount of them to die .All of those problems and effects that resulted from animal cruelty will definitely someday affect us weather in diseases or in decrease of food or pollution of water just like what we did to other
They’re also tolerant of a broad range of environmental and climatic conditions, making them able to occupy many habitats. There are concerns that cane toads are the key factor in the decline of many native species. They endanger native frogs by consuming far more prey than them, approximately 200 food items per night, causing native frogs to need to compete for their food. They also possess highly toxic chemical predator defences which can kill many native predators, such as snakes and lizards that attempt to consume them (The biological effects, including lethal toxic ingestion, caused by Cane Toads). Due to these effects on the environment, a solution to the cane toad issue is urgent.
The illegal hunting and trade of primate meat is a large contributing factor to the decline of primate species in the tropics. This, in addition to habitat loss and fragmentation, disease, and the pet trade, is putting many primate species at high risk of extinction. Poverty, population growth, construction of roads, emergence of regional and international markets, and new hunting technology are triggering the increased hunting pressure on forest mammals. Primate species are especially vulnerable to increased hunting pressure because of their slower reproductive cycles. The decline of primate species must be stopped to avoid their extinction and the potential consequences that this could have for tropical forests.
