Answer:
The poor people
Explanation:
The poor people always the ones that suffer the most when there are negative changes. They are not financially capable to avoid the problems that come upon them, and plus they are overly dependent on the nature for their survival. These people can not afford or do not have healthcare that is eligible, so if there is a pandemic they will be the first ones affected, and by far the most affected. They depend mostly on agriculture for their survival, and it is agriculture in more primitive manner, which is the one that suffers the most from the climate changes and the natural disasters. If the crops fail dramatically only one year, it will have huge effects, if that happens several years in a row, it can be one of the biggest, if not the biggest humanitarian crises in the world.

In areas at the equator, the angle of incoming rays from the Sun is perpendicular (90 degrees) to the Earth's surface during all days of the year. Such areas experience warm climates throughout the year
