Global climate change is when a change in weather appears in an area where it normally wouldn't. This is normally a change in the temperature, precipitation and/or wind. An example would be the ice caps melting in Antarctica because heat is making its way in where it should not be.
<h3><u>Difference between urban and rural areas:
</u></h3>
<u>Urban areas:
</u>
- These areas are large and almost planned settlements fabricated through a process called urbanization.
- Large and diverse populations reside in these areas. The allocation of natural and man made resources is also properly planned in urban areas. Industrial settlements are more in number than agricultural settlements.
<u>Rural areas:
</u>
- These areas are comparatively smaller in size and lack proper planning in settlement.
- The use of natural resources is often unsupervised. These areas also lack modern facilities and amenities.
- The population of these areas is substantially low and most of the population depends on agriculture and allied activities to make a living.
So, the question is asking: why has (over the course of human history) rural settlement declined (and it is suggested that this is connected to humans moving away from the rural areas, to urban areas, rather than human population declining in general:
this process is called urbanization and its major cause is that on the one hand, food in the industrialized societies can be produced more effectively so there is less work on farm, and on the other hand the service sector has increased, which means that there is more work in the cities.
