more efficient. Coal began being used as the new fuel source as it provided five times the heat that firewood did. “Britain had an advantage over other European countries because its mines were near the sea‚ so ships could carry coal cheaply to the most important market.” (http://www.bbc.co.uk/history/0/20979973) Coal was used to power many of the new factories. The second necessity is basic inventions; over time new technology had to be thought up by inventive thinkers to keep the coal production levels

What is Global Warming? Global Warming is defined as the increase of the average temperature on Earth. As the Earth is getting hotter‚ disasters like hurricanes‚ droughts and floods are getting more frequent. Over the last 100 years‚ the average temperature of the air near the Earth´s surface has risen a little less than 1° Celsius (0.74 ± 0.18°C‚ or 1.3 ± 0.32° Fahrenheit). Does not seem all that much? It is responsible for the conspicuous increase in storms‚ floods and raging forest fires

These air pollutants are the major cause of smog and acid rain. The burning of fossil fuels such as coal‚ oil and gasoline emits these air pollutants as by-products. Energy consumption and residential wood heating is the greatest single source of air pollution in Canada. These air pollutants cause a lot of respiratory and cardiovascular problems in human

less then 5.0. Major primary pollutants produced by human activity include: * Sulphur oxides (SO4) - especially sulfur dioxide‚ a chemical compound with the formula SO2. SO2 is produced by volcanoes and in various industrial processes. Since coal and petroleum often contain sulfur compounds‚ their combustion generates sulfur dioxide. Further oxidation of SO2‚ usually in the presence of a catalyst such as NO2‚ forms H2SO4‚ and thus acid rain. This is one of the causes for concern over the environmental

realized the need for crop rotation to prevent soil erosion. In Europe‚ the plague prompted improvements in the public health system‚ particularly to improve the water. Also‚ due to Englanders nearly depleting all of their forests‚ they switched to coal—a resource that would later cause many more health problems‚ especially in the larger cities. Beyond that‚ as health problems arose over the centuries‚ people saw a need to improve their environment. The environmental movement became more organized

Air Pollution: Air pollution is the introduction into the atmosphere of chemicals‚ particulates‚ and biological matter that cause harm to humans‚ other living organisms‚ or cause damage to the natural environment.
