Answer:
Earth's tilt towards the sun will gradually cause the northern hemisphere to experience summer during today's current winter.
Explanation:
It is expected that over the next 13,000 years, the polar region, particularly the north pole will be tilted gradually towards the sun. At that time, the earth will be in the closest position towards the sun. The tilt would be along the axis and also orbital. Henceforth this both forms of earth's tilt towards the sun, will expose the northern hemisphere to maximum solar radiation, this will cause the region to experience summer during winter's time.
Since pathogens are easily passed from person to person, they need large populations to spread and survive. If they did not have a large population, the pathogens would die out.
