1.The Gulf of Mexico oil spill, the worst in maritime history, dumped 4.2 million barrels of oil, and officials released 1.8 million gallons of Corexit, a chemical dispersant used to break up the oil, into the Gulf before the well was sealed. Six years later, controversy still rages about the wisdom of carpet-bombing the Gulf with these chemicals, and newly released documents reveal that government scientists expressed concern at the time about the health consequences of mixing such large quantities of dispersants with the millions of barrels of sweet crude. Occupational health experts now believe it created a toxic mix that sickened thousands of locals — including some of the 47,000 people that worked in some capacity on BP’s cleanup operation — crippling them with chemically induced illnesses that doctors are unable to treat.

2.
Within the field of conservation ecology, the importance of invasive species has long been recognized. Invasive animals are of particular concern when they are vertebrate carnivores, perhaps because these taxa are able to persist in diverse habitats and once comfortably embedded in these novel setting, are often able to instigate strong declines in prey species, or indeed, trophic cascades. The pages of Animal Conservation are littered with articles on invasive vertebrate carnivores.

Two carnivorous species blur the line when it comes to assessing whether a taxon is invasive: the domestic dog and cat. Because they are often desired and subsidized human commensals, we rarely consider the ecological role of these species when they are either unowned or beyond the control of their ‘owners’. Thus while conservationists, and sometimes the general public, are often attuned to some concerns regarding the impacts of cats on birds, or the potential for dogs to hybridize with wolves, many in this same audience are unaware of other concerns regarding these predators. While recent syntheses have served to bring these issues to the forefront for ecologists and conservationists, much remains unclear. For example, in some landscapes, free-ranging dogs and cats have existed for thousands of years. Furthermore, in some localities, free-ranging populations of these species may serve as ecological surrogates of native carnivores that have been lost due to anthropogenic impacts. Recognition of such patterns suggests that understanding the impacts of domestic dogs and cats on wildlife requires in-depth research and nuanced interpretation of the ensuing data.

  1. The Gulf of Mexico oil spill dumped 4.2 million barrels of oil, 1.8 million gallons of Corexit, a chemical dispersant used to break up the oil, which brought the attention of government scientists and health experts that they expressed concern about health consequences of mixing such large quantities of dispersants with billions of barrels of sweet crude, that created a toxic mix that sickened thousands of locals.

  2. 1. Recent revelation associated with the Gulf of Maxico oil spill incident shows that the government scientists are obnoxiously concerned about the consequences of mixing large quantity of dispersants in ocean; which has affected numerous people in the locality and doctors are still struggling to find the remedy against chemical illness.

  3. The Gulf of Mexico oil spill was contained using chemical dispersants, but according to experts excessive use of chemicals caused several health hazards to locals.

  4. Hi Admin,

    I am not sure about the below summary this time, can you please have a look and give your comments ?

    Once adapted invasive species especially vertebrate carnivores affects prey species and hence ecology but the impacts of pet dogs and cats on wildlife or ecology still needs further research and study.

  5. Oops…..posted the rough one. This one is final

    **Once adapted, invasive species especially vertebrate carnivores affects prey species and hence ecological balance but the impacts of pet dogs and cats on wildlife or ecology still needs further research and study.

  6. Now scientists are concerned with the large quantities of dispersants (Corexit) which was used to break the oil spill in the Gulf of Mexico, is causing chemically induced illness among the locals and those people who worked in the BP cleanup operation

  7. Government of Mexico oil spill had released 4.2 million barrels of oil into the sea along with 1.8 million gallons of corexit which later on initiated dangerous diseases amongst the people that doctors cannot cure it.

  8. The massive use of chemical dispersant to clean up oil spills in Mexico gulf has lead to major concerns of health consequences for local residents because close contact with the toxic dispersant could possibly result in untreatable illnesses.

  9. Invasive animals impact on other wildlife is recognized under the field of conservation ecology, ecological role of cat and dog is rarely consider, when either they are unowned or beyond the control of their ‘owners’.

  10. Gulf mentioned 1.8 million gallons of oil mixing with dispersants instead of 4.2 million barrels which is concerned point for the Scientists, it created a toxic mix which is harmful effects to workers, doctors are unable to cure.

  11. Mixing of chemical in order to break up the sweet crude oil has created a toxic mix in The Gulf of Mexico and after six years, serious incurable health consequences have been created among the locals as thousands of people sickened especially those who are working in BP’s cleanup operation.
