I found this article very interesting, it relates to Green GDP. The Indian government is aiming to use natural resources, and fight global warming, India is one of the most affected countries due to global warming. India's stand in the fight against global warming will let them be in a better position on negotiations about cutting emissions by an average of 5 percent below 1990 levels by 2008-12 which take place in Denmark. India has no obligations to actually reduce emission as it is still a developing countries and as it says in the article it is a "proof of its sincerity in fighting climate change". The Indian governmen t will even consider their Green GDP as part of their economic growth. This won't be an easy challenge for India though due to millions of people living in poverty and having to burn fossil fuels so their lives improve.

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.

A negative externality is a cost incurred by a comapny or a party that did not agree to whatever action caused the extra cost. This article discusses the negative externalities that we incur when we use fossil fuels etc. The cost of production and damage caused by the use of fossil fuels is not included in the price we pay for 1 gallon of gasoline. This is the negative externality. A lot of the government involvement in the private sectors is actually aimed at reducing such negative exteranlities concerned with environmental pollution. Several companies also try to reduce externalities by introducing policies. For example, SAP AG has policies that its employees cannot buy cars that have carbon emissions beyond a certain limit.

Your article is very interesting. In the end the writer talks about the oil spill in the Gulf of Mexico, two weeks ago or something like that I read that BP (they were the owners of the deepwater Horizon) will pay $4.5 billion in fines and other payments, the largest of its kind in US history. It is a lot of money but how can we estimate the value of million animal life's and the destruction of a big part of the Gulf of Mexico. The worst is that we could avoid it because the BP company saved money in the security systems in these Deepwater. I think that after this disaster the government should check all the deepwaters in order to reduce the possibilities of new cases.

A negative externality is an action of a product on consumers that imposes a negative side effect on a third party. Many negative externalities are related to the environmental consequences of production and use. for example the emmisions of green house gases. in this article it explains that when i company creates negative externalities neither the company nor the consumer pays for them so there the government has to step in to stop it by ptting regulations which increases the cost of the comapanies decreasing the negative externalities. but national companies complain because they say if regulations are set they cant compete with international firms like in china where there are no regulations for fuel negative externalities. for example a negative externality was the gulf of mexico oil spill where BP oil prices didnt rise to clean up the mess but the taxes did

This article talks about an international event that will be held in Astana, Kazakhstan in 2017. Kazakhstan expects three to five millions of visitors. Such event will beneficially affect the economy of the country. It will not only result in an economic growth, but will possibly lead to a significant boost in economic development. The topic of the Expo 2017 is Future Energy. Such topic will lead to the development of the sustainable ways of using energy. Using sustainable ways in the first place for Kazakhstan would mean using approaches that will decrease the air pollution. Decrease in air pollution can be considered as an improvement of the quality of life and improvement of the welfare of country. In my opinion, Expo 2017 is a very important event for Kazakhstan as well as for the rest of the world. It will significantly impact the economy of Kazakhstan. Preparation part is one of the main stages of the Expo. It will create a lot of new jobs, due to constructions that will be held in Astana.

This is a good article talking about the tragedy of commons in both rural and urban areas, where mostly, the tragedy tends to happen in cities. For the instance, usually they are: traffic jams, and green hose gases.The author also states some possible solutions for those problems.

This article talks about the tragedy of commons. The governments are ignoring that instead of reducing the costs and the money used in the public sector they could try to cause an economic growth. This would be better for everybody because the economic growth reduces the deficits better than spending cuts. If we are doing spending cuts in the future we will have to spend a lot of money to fix the common resources and facilities used by all, including our air, water, and public infrastructure. If the problem amount then we will have more difficulties to solve them in the future, we can't leave them for the future generations because we have created those problems and we must solve them.

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.
