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.
Some air pollutants cause more global warming. Air pollution includes greenhouse gases. One of these is carbon dioxide, a common part of the exhaust from cars and trucks. Greenhouse gases cause global warming by trapping heat from the Sun in the Earth s atmosphere.ir pollution includes greenhouse gases.
