Solution

The correct option is C All of the above

The rise in the average temperature of earth has been described as global warming which is mainly attributed to the increasing phenomenon of the greenhouse effect. It is believed that global warming can have several harmful effects on human health, both directly and indirectly. Since malaria is greatly influenced by climatic conditions because of its direct relationship with the mosquito population, it is widely assumed that its incidence is likely to increase in a future warmer world.

As global warming continues, malaria is set to spread in locations where previously it was limited, due to cooler climate. On the other hand, several theories have been put forward which are quite contrary to this prediction. There are multiple other factors which are accountable for the recent upsurge of malaria: for example drug resistance, mosquito control programs, public health facilities, and living standards. Due to the rising global temperature, more areas of the world will become favourable for the survival of tropical insects like mosquitoes. This could lead to the spread of these insects towards more northern and southern hemispheres and to higher altitudes. Some species of mosquito act as disease vectors and are responsible for the spread of illnesses like malaria, Dengue fever, and Yellow fever. Hence, global warming can increase the incidence of these diseases
