The DNA repair ability of a cell is vital to the integrity of its genome and thus to the normal functionality of that organism. Many genes that were initially shown to influence life span have turned out to be involved in DNA damage repair and protection.
Examples for negative production externalities include: 1  Air pollution from burning fossil fuels. 2  This activity causes damages to crops, (historic) buildings and public health. 3  Anthropogenic climate change as a consequence of greenhouse gas emissions from burning oil, gas, and coal.
Air pollution can create some major health problems. Highly polluted air has been shown to cause a burning effect in eyes, noses and throats. Polluted air also makes it harder for those with asthma to breathe. Some toxic chemicals that can live in the air -- like benzene and vinyl chloride -- are highly toxic.ut all of those hours spent outside were actually good for more than using up our unlimited, childhood energy. As it turns out, science shows that some fresh air really will do you good. Fresh air saves lives.
