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.
Along with harming human health, air pollution can cause a variety of environmental. effects: Acid rain is precipitation containing harmful amounts of nitric and sulfuric acids. These. acids are formed primarily by nitrogen oxides and sulfur oxides released into the. atmosphere when fossil fuels are burned.
