Increase in Pollution this is mainly because of Industries pollutants releasing from industries. In the year 2020 due to Covid -19 Lockdown we can observe the positive changes in environment.

there are 3 kinds of intervals
The number of contour intervals on a topographic map is determined by the range in elevation from the lowest point to the highest point in the area being mapped.
Generally speaking, the greater the range in elevation, the more contour intervals need to be used. For example, if the range in elevation is just a few meters, then it will have just two contour intervals. In contrast, if the range of elevation is very large (e.g. tens or hundreds of meters), then the topographic map may have up to 10 or more contour intervals.
The contour interval of a topographic map also depends on the purpose of the map. For example, if the topographic map is intended to show small variations in elevation, then a smaller contour interval will be used. On the other hand, if the map is intended to show larger variations in elevation, then a larger contour interval may be used.
In addition, some topographic maps may also include supplemental contour intervals that are used to highlight areas of special interest, such as a mountain peak or a stream.

Most of the economic activities in the middle ages centered around agriculture.
During this time, the majority of the population was engaged in farming and related activities, such as animal husbandry, forestry, and fishing. Farming was the primary source of food and income, and the main way to produce the goods necessary to support a feudal economy.
In addition to agriculture, there was also some limited trade within and between countries. Trade was especially important in areas where there was a surplus of goods that could be exchanged for items that were scarce in other areas. Merchants would travel throughout Europe to buy and sell goods, often using the network of trade fairs that had been established.
Crafts and manufacturing were also important during the middle ages. Blacksmiths, carpenters, tinkerers, and other skilled artisans were in high demand to produce the tools, weapons, and other items necessary for daily life. In some areas, guilds were formed to regulate the quality of the goods produced and protect the interests of the artisans.
Finally, services were also a major part of the economy. People were needed to operate mills, transport goods, and provide other essential services. These activities were often done by hired laborers, although in some cases the services were provided by slaves.
