The digestive function of the liver is to produce bile, which is a fat emulsifier. Bile is a yellow-green, alkaline solution containing bile salts, bile pigments (primarily bilirubin), cholesterol, neutral fats, phospholipids, and a variety of electrolytes.he digestive function of the liver is to produce bile, which is a fat emulsifier.

The use of fossil fuels (coal, oil and natural gas) is a problem because the burning of these fuels in industry, transport and the generation of electricity releases carbon dioxide (CO2).This is causing global warming and climate change.: The combustion (burning) of fossil fuels releases poisonous gases into the atmosphere. Oil/Petrol, for instance, is a Hydrocarbon (a mix of Carbon and Hydrogen atoms) and when burnt with Oxygen creates Carbon Monoxide and Carbon Dioxide.
Fossil Fuels and Energy Use. Fossil fuels are natural resources such as coal, oil (including gasoline and diesel fuel) and natural gas. They are formed from the remains of ancient plant and animal life. Fossil fuel burning powers our vehicles and industries, heats and cools our buildings, and runs appliances.It also produces electricity that we use for all sorts of purposes, such as lights and computers.hese pollutants include carbon dioxide (CO 2) and methane (CH 4), both of which are major greenhouse gases, as well as particulate matter (PM), nitrogen oxides (NO x), sulphur oxides (SO x) and carbon monoxide (CO). When we burn fossil fuels, burn wood for heat, and use electricity, we are using energy.
