Question 1:
Vector borne disease are demarcated as the infectious disease which is transferred to the
human by the vectors which includes, licks, fleas, rodents and lice. Change or alteration in the
climate make the vectors which are responsible for the disease to multiply and spread more
rapidly causing the disease.
Effect of climate change:
The pathology of the vector born disease is complicated and depends upon the life cycle
of the vector which is influenced by the change of the climate. These transmission cycle of the
vectors and the disease recurrence rate is increased as change in the humidity and temperature
which is due to the climate change make the vectors proliferate faster (Medlock & Leach, 2015).
Change in the climate also influence the distribution of the vectors by providing them suitable
habitats for the better proliferation.
Effect of green house:
Greenhouse effect is the natural phenomena which makes the surface of the earth warmer
and is also responsible for the climate change. As due to the presence of the more greenhouse
gases, the air will be able to hold more amount of heat, warming the surface of the earth leads to
climate change (Eckelman & Sherman, 2018). Due to which the rainfall pattern is also effected
posing an impact on the infectious disease which is transmitted through the vectors such as insect
vector through the stored contaminated water.
Effect of human activities:
With the increased human population, rate of the infectious disease are also increasing.
Humans are somewhat responsible for the other factors such as, globalization, urbanization and
