What is the connection between Immanuel Wallerstein's theory and the global e-waste trade?

A country called Sherwood is very heavily covered with a forest of 50,000 trees. There are proposals to clear some of Sherwoods forest and grow com, but obtaining this additional economic output will have an environmental cost from reducing the number of trees. Table 12.11 shows possible combinations of economic output and environmental protection. Sketch a graph of a production possibility frontier with environmental quality on the horizontal axis, measured by the number of trees, and the quantity of economic output, measured in corn, on the vertical axis. Which choices display productive efficiency? How can you tell? Which choices show allocative efficiency? How can you tell? In the choice between T and R, decide which one is better. Why? In the choice between T and S, can you say which one is better, and why? If you had to guess, which choice would you think is more likely to represent a command-and-control environmental policy and which choice is more likely to represent a market-oriented environmental policy, choice Q or S? Why?

As the extent of environmental protection expands, would you expect the marginal benefits of environmental protection to rise or fall? Why or why not?

Radio stations, tornado sirens, light houses, and street lights are all public goods in that all are nonrivalrous and nonexclusionary. Therefore why does the government provide tornado sirens, street lights and light houses but not radio stations (other than PBS stations)?
