Heat stress hits labour productivity - 1 views

  •  
    This article shows how the environment can influence the aggregate supply in the economy. The article states that heat stress from global warming may be having an impact on outdoor work productivity in hot regions like northern Australia, Southeast Asia and the southern US. And the calculation tells us thatin temperate regions, people work continuously, but in the hottest places, the working day is split between 80% work and 20% rest. Therefore, people and government should pay attention to the environment problems nowadays because it will lead to a change in nation's GDP. And economists also should consider environment as a determinant of aggregate supply.

    This article talks about how global warming is causing a decrease in work productivity, which would lead to a decrease in production. It states that in the hottest months of the year, labour capacity decreases by around 10%. They estimate that by 2050 the temperature would have risen by 1.8 degrees. At this temperature labour capacity would decrease by 20%. So overall this could have huge effects on the economy as production will decrease, and therefore there will be over aggregate demand. this then would cause inflation.

The hidden green costs of progress - 0 views

  •  
    This article talks about the importance of caring about the environment because this year there have been alarming weather activities possibly caused by climate change: Droughts, floods, the record melting of Arctic ice and the recent Superstorm Sandy. We can´t affirm that this happened because there is a change in the climate but we have to admit that this is one of the possibilities. If we don´t do nothing the situation will be getting worst. The water level is increasing more than we have predicted and many specialists admit that San Francisco and other cities near the coast might be under water in 20 years. Retrospect, we have neglected the full costs and hidden environmental price tags of economic progress. Only if we are aware of the externalities of our actions can we then build a more organic living environment and actively cut down emissions.

tragedy of the commons - 0 views

  •  
    Nowadays, people just keep ruining the environment, that cause a damage for us in the future, if we won't make a rules and limits about this. For example, every people have the right to fish without any limits. If we keep doing that, the fish will decrease and it might become extinct. So the government should make rules for every action that will harm the environment as mush as they could to protect them.

Pollutions from oil refinery accidents on the rise in Louisiana. - 2 views

  •  
    Pollution from the Motiva refinery in Norco, Louisiana has been a major pollutant in the region since 2005, and it doesn't show signs of stopping. There have been 301 reported cases of accidents in 2011 and many more unreported. The firm may be only concerned with its marginal private costs and have no intention in even dealing with the marginal social costs caused by the negative externality. The government must intervene and cease this crime; the injustice towards its community, society and the environment.

    I didn't heard about this case before. I find it ironic because USA with their great judiciary don't have methods to fight with companies like Motiva. We can ask ourselves who is worst a murderer who kills one person and is sentenced to death or a company who is killing hundreds of humans beings. The oil is very important in our live, we need it every day but we must ask as where is the limit? what is more important a human being or using a car? We have to eliminate negative externalities like pollution because if we don't do anything then we will destroy the world because we have infinite wants (this is the sad reality).

Ending the Oceans' 'Tragedy of the Commons' - 0 views

  •  
    Oceans are one of the Commons, and as any other commons, it becomes overconsumed. Fishers all around the world keep devastating populations of the fish. To prevent overfishing, pollution and other human impacts, leading international marine scientists are proposing radical changes in the governance of the world's oceans. They carried an experiment in Chilie, and based on it, scientists state that they would be able to help to reverse "the tragedy of the commons". Problems in Chilie made people be open to new arrangements, scientists and fishers began working together to improve the situation with fish. By working together for some years, scientists became able to reveal about fish stocks and and the surrounding marine ecosystem. The new laws gave exclusive ocean territories to local 'artisanal' fishers, and excluded the big industrial fishing fleets, which had their own exclusive fishing zone. Scientists and small fishers then worked together to understand and rebuild the shattered fish stocks in their zone, leading to a shared vision and voluntary agreements on how to manage them.

    This article talks about an experiment made in Chile. The use given to our oceans are no good, the article encourages huge changes in the governance of world's ocean to save them from pollution, over-fishing and other impacts made by the humans. All of these factors affect the marine ecosystem in a drastic way, now the levels of fish are decreasing as it says in the article "There was a general recognition that Chile's fish stocks were in trouble," says Professor Carl Folke. This has led to some fisheries to collapse leading the Chilean government for being responsible to take actions.This serves as an example of what's happening in the world today and for facin this problem he suggests that "You need a shared recognition that something has to be done, you need a good understanding of the marine ecosystem and how to regenerate it, you need a strong rapport between scientists and fishers, and you need a political moment when sweeping changes can be brought in." This problem needs to be faced responsibly otherwise there will be almost no fish stocks in the future, treating our commons well is important for us humans as this affects goods that are importand for living.

    Leading international marine scientists are proposing radical changes in the governance of the world's oceans to save them from overfishing, pollution and other human impacts. "Marine ecosystems are in decline around the world. New transformational changes in governance are urgently required to cope with overfishing, pollution, global changes, and other drivers of degradation. Fishers and scientists had been working together on the problem for some years, trialling new co-operative models for fishery management, based on that science can reveal about the state of the fish stock and the surrounding marine ecosystem." The result is a national system of marine tenure that allocates user rights and responsibilities to collectives of fishers. The research indicates the key to managing fisheries depend on creating agreements that are both voluntary and flexible enough to cope with changes in the ocean environment, leading to fisheries that are both ecologically and socially sustainable.

    I find this article particularl interesting because due to a political change in Chile, it has now effected the common resource tradegy of the Oceans. It has reduced the over fishing in Chile, which has let the fish start to regenerate. The research has found out that the key to managing the fisheries depends on making decisions flexible enough to cope with the changes that the ocean goes through.

Tea Party Movement - 0 views

  •  
    This article is about the Tea Party supporters who sprang into action in the United States last year. They demand to block the democratic agenda on the economy and also the environment and health care. Tea Party supporters are Republicans and believe President Obama and the Democrats to be 'far too liberal'. These supporters are strongly backed up by Republican politicians, Sarah Palin in particular. One of the major issues that the tea party argues is the misuse of economic resources in health care. They feel that all the health care opportunities are targeted towards the poor section of the country, not the middle or rich class. However since the latter are tax payers, the health benefits should be more focused on them. Thus in this situation a political party has a direct influence on the economic policies taken in a country.

Tragedy of the Commons- Climate - 1 views

  •  
    It is interesting to note that economists put the blame of climate problems on economic market failure. One of the externalities responsible they say is the ' greenhouse gas negative externality'. it is considered a negative externality because the effects of the activities are not felt by the people who conduct these activities but by future generations. So a different party feels the effect which defines an externality.

Aggregate supply alert- Lafarge - 0 views

  •  
    The cement company Lafarge, says that UK faces a 200 million tonnes shortfall due to slow planning procedures. There is an extremely high demand currently in the UK. If this continues or increases, then the countries capacity to supply will begin to decline after 10 years. Out of the 200 million tonnes, only 60 is recyclable which leaves the rest to be extracted from primary sources. Since the procedure to quarry materials from primary sources requires authority permission, the process is very slow. This slow process is going to create the shortfall says Lafarge.

For OPEC, Current Oil Price Is Just Right - 0 views

  •  
    This article talks about what should be the equilibrium price for a barrel of oil that benefits both the consumer and producer. The OPEC (Organization of petroleum exporting countries) talk about how high prices help the petroleum organization make investments in renewable fuels, but high priceces would hinder consumers as they now have less to spend on other products. The OPEC also talks about the effects of low prices where it would benefit the consumer but disadvantage the producer investing in renewable fuels. Therefore they have come to the conclusion that the price of a barrel of oil should be between 70-80 Dollars a barrel where bothe the producer and the consumer are happy. Saud Arabia ( the biggest exporter of oil) has agreed to the price of 75 dollars a barrel.
