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.
The pollutants released into the atmosphere cause local air pollution (see Table of Common Pollutants). However, they also cause regional air pollution, as with huge plumes of smoke covering a large area, and acid rain.n some cases, air pollutants contribute to climate change, and greenhouse gases contribute to air pollution: 1  Air pollutants such as ground-level ozone and soot (a portion of particulate matter) contribute directly to global warming, which is linked to climate change.
