Problem 1. The concept of "technosphere" is used when there is a mean residence
people in the biosphere, but also what made it change operations;
the concept of "anthroposphere" is used to refer to the Earth's surface, inhabited by people;
the concept of "sociosphere" almost coincides with the concept of "Technosphere", but unlike him, includes
a whole set of social factors specific to the state of society in
interacting with nature.
Place the concepts:
in order from the more simple concepts to more complex concepts.
Problem 2. In economic theory, widely used functions:
1. ƒ (K, L)
2. Ft (L, K, N, l)
Where L - labor resources, K. artificially created capital, means of production,
N - natural resources, l - institutional factor, t- time.
What are the model of global development describe these functions?
Problem 3. In Russia the cost of forest resources for the production of 1 ton. Paper of 32 m³,
and in Finland - 5 m³. Find the ratio of indicators of environmental capacity of the manufacturing industry
in Finland and Russia.
Problem 4. In assessing land rental is widely used approach. Rate value
land P, if annuity land R = 10,000 rubles. And the bank
lending rate r = 10%.
Task 5. The air in the region pollute two companies:
Emissions Specific costs to eliminate emissions
1 - the company 30,000 tons / year 5 rub. / T.
2 - the company 40,000 tons / year, 20 rub. / T.
The total volume of pollution in the region should not exceed 50 000 tonnes. Calculate the total
the cost of elimination of emissions in the following cases and indicate which option decision
a better solution:
Option 1: a reduction in the emissions at each plant by the same amount in
10,000 tons / year.
Option 2: a reduction in the emissions of the first company of 20 000 t / year.
