Step-by-step explanation:
There are many reasons why people help each other. In some cases this is due to the fact that human beings have a feeling of empathy, which corresponds to putting themselves in the other person's shoes and therefore being motivated to help them when necessary. There are also ethical values that are shared by society, that we must act with solidarity and help those in need.
It is correct to say that genetic and environmental variables increase the likelihood that one person will help another, but the environmental factor may be stronger in the case of unexpected events, such as an environmental and social tragedy, conflicts, etc.
It is important to establish a sense of empathy in society, it is through it that relationships happen in a better way and people can live better and be happier.
