Can a single cause have several effects?

In almost all areas of life, single causes do have several or multiple effects.

For example, a woman gets pregnant. At first it might cause her great stress and worry. She decides to have her baby but has complications. The pregnancy complications prevent her from continuing to work. Because she cannot work, she lost her income and healthcare benefits. Although she had planned to marry the father, he walked out because of growing stress in the situation. She is now alone with no money to pay the rent, utilities, buy food, etc. Her own stress continues to build, leading to increased blood pressure. The high blood pressure threatens her fetus's health. Her doctor decides to put her in the hospital. By her 2nd trimester, she must go on Welfare, get food stamps, and a medical card. After being released from the hospital, she has to live with her parents. She loves her parents but wants her independence. They help her get another apartment but the money from Welfare barely pays minimum expenses. She worries, while moms in better situations enjoy their pregnancies. Worse, society is often judgemental. When she uses food stamps at the grocery store--even for only health foods--people make nasty remarks about how their tax money is "going to another druggie" even though she never used drugs. The comments make her cry. Her self-esteem plummets. It's hard enough for women to think of themselves as beautiful when they are gaining pregnancy weight. "I'm so fat!" she criticizes herself. Misguided by feelings, she deliberately doesn't eat. The doctor notices she lost weight and is concerned; the baby needs nutrition. He puts mom back in the hospital so she'll eat. The 1st hospitalization cost society thousands of dollars; the 2nd hospitalization costs four times as much as the first. Again back home, mom tries to prepare for her baby. But she has no money to buy nice things. Her parents can't help more. So she feels she is "failing" as a mother before the baby even arrives. By the time her baby is born, mom is so beaten down, emotionally hurting, financially worried, stressed and distressed, depressed and disillusioned, and doesn't know why she ever allowed herself to get into a position that she had unprotected sex. All of these "effects".... from one single "cause".... all because a sperm met an egg... all because of one choice.

I used this example because it's one of the easiest examples to show cause and effect. But, almost every single decision or action we take in life can lead to several effects, some good, some bad, and some in-between. The only way to avoid effects is to never act--- but even inaction has effects.
