At the current rate of growth, earth's human population will double in about 50 years. which of the following is the least viable strategy for ensuring adequate nutrition for a population of this size?
a. increasing the number of new crops from the great diversity of plant species
b. doubling the area of arable land on a global basis
c. developing systems for making the global distribution of food more equitable
d. increasing the area of land that is currently dedicated to grain production by reducing the area dedicated to meat production
e. assisting developing countries in using highly efficient crop irrigation systems

Doubling the area of arable land on a global basis

Explanation:

Here, the least viable option or strategy has been asked. Doubling the area of arable land on a global basis is the least viable option because it is quite impossible in the given circumstances. At the moment, year by year, the arable land on planet earth is actually decreasing due to the aggressive agricultural techniques and chemical usage for harnessing more output has contaminated the top soil in many regions. This means that the crop output and the arable land both are decreasing. Also, floods and other natural disasters affect or decrease arable land as well. Hence, doubling the current arable land 1.5 billion hectares globally which is 11% of the globe is pretty impossible in the current situation.

all cities have a governor

all cities are in states or provnies then country

all cities have people

some are rich

some are poor

some are average

marginal cost is a microeconomic measure that us to evaluate the extent to which the level of production of a good is sustainable in accounting, that is, to how many quantities the company plans to profit from the production of the good.

the concept of marginal cost is simple, it means the cost of producing one more item. for example, in the case of pies, the marginal cost is the cost of producing one more pie than those that have already been produced.

it is important to understand that productive activity influences marginal cost. the marginal cost of some goods can be very high, while others may be insignificant. for example, the marginal cost of producing an extra plane is very high. already the marginal cost of a water company to provide 1l more water is derisory.

in the case of pies, the cost involves the inputs, the labor and the fixed cost, which involves the fixed space of the bakery. the level of production initially has the marginal cost decreasing because there is space and manpower available. however, to produce more you have to hire more workers and buy more inputs. if physical space is limited, workers will conflict with places, inputs and their productivity will decrease, meaning there is an optimum point of production for each level of space and manpower. from this point on, the productivity of the workers will be getting smaller because of lack of space, so that the marginal cost of producing one more pie will be increasing. so, although you have not posted the chart, but if you have the answer, you can see that my explanation goes according to the marginal cost curve that will increase from the 4th pie, answer (c).
