Coal is cheap, making it especially useful for developing nations, but it also releases carbon dioxide and particulate matter. Coal reserves are high in many nations. Coal plants are also relatively simple and are easy to build.Continue Reading
Coal has long been valued for its high-energy content, and ancient civilizations would use it as a source of heat. When early steam engines were in use, they were generally powered by burning coal. Coal plants are fairly simple to build; a coal-burning fire heats water, and the steam created turns large turbines. While natural gas is almost as cheap as coal, China and other energy-hungry nations prefer coal plants.
However, coal also releases a tremendous amount of carbon dioxide when it burns, and many developed nations are phasing it out as a result. However, China and other nations lack the capital needed to use more expensive sources of energy. As its economy continues to grow at 10 percent per year, China needs more and more energy, and coal is the most viable option.
There are ways to make coal a cleaner source of energy, and the particulate matter it generates can be caught. However, capturing and storing carbon dioxide is difficult and expensive, and experts are skeptical of whether storing it underground is a feasible solution.Learn more about Geology
Most cars have a typical combustion engine that burns fuel for energy, which results in the production of a wide variety of harmful chemicals like carbon dioxide, volatile organic compounds and particulate matter. Additionally, cars require several liquids to run that are toxic to people, animals and plants.Full Answer >

International trade may help countries improve their own economies as well as those of other nations involved in business transactions, but it can also heavily favor large companies, leaving small businesses without a market. Global or international trade, such as commerce and sales at the national level, may help organizations expand their networks, reach new consumers and contribute to significant economic growth. However, international trade may also put small companies, such as family-owned and local operations, at a disadvantage as they cannot reach the same volume of consumers and provide competitive prices.Full Answer >
