Globalization is the term that is used to describe the integration of international technology, communication and products. It is the linking and sharing of cultural and economic activities between different countries. Over the last century the emphasis on globalization has increased as countries have been more willing and able to communicate and interact with one another. World governments, organizations and businesses are continually working towards greater international integration as a way to improve and develop the world as a whole. As globalization continues to be advanced and encouraged it is important that we understand the advantages and disadvantages of international integration.
Natural gas is one of the most important energy sources in the world. As the name suggests it is a naturally occurring gas containing mostly methane with some other hydrocarbons and impurities. Natural gas is a fossil fuel and is often found underground along with other fossil fuels, such as oil and coal. It is extracted much the same way as oil and is often obtained as a byproduct of this process. After extraction it undergoes processing to remove the impurities and clean the gas. It is commonly used for heating, cooking, electricity generation, as a vehicle fuel and for a variety of commercial and manufacturing uses. Let’s take a look at some of the advantages and disadvantages of this fossil fuel.
Renewable energy refers to any energy that is created using a natural source and is sustainable. Some common forms of renewable energy include solar, hydroelectric (hydro), wind and geothermal. Much research is being invested into these sources of power to make them more cost effective and reliable. Renewable energy is sustainable and better for the environment making it a growing area of industry. Even though there are many benefits of renewable energy three are also some disadvantages to this form of energy. This article will focus on some of these disadvantages.
High altitude training has become one of the most popular methods of training for endurance athletes. It is highly promoted by many sports scientists and personal trainers for the potential benefits. Altitude training can be completed by training at least 1,500 meters above sea level or by using a system that simulates the effects of altitude. It is widely being used by athletes from many professional sports because of the advantages of this type of training.
Geothermal power uses the heat from the earth’s core to create electricity. Most power plants use steam driven turbine to create electricity. This is the same in geothermal power plants. The heat from the earth is used to create steam or the steam that is directly released from the earth is used to drive the turbines. Geothermal power is used in 24 countries around the world and is considered to be a renewable and environmental friendly power source. The United States used the most geothermal energy with the geysers in California powering a total of 15 power plants. The Philippines and Indonesia also produce a lot of geothermal power.
Hydroelectric power is electricity that is generated by using the movement of water. To create electricity a power source such as steam, wind or running water turns a turbine. The turbine spins a large magnet or many large magnets inside a coil of copper wire. This creates mechanical energy which is converted into electrical energy via the magnets and copper wire. This electricity is then stored and sent through electrical wires to houses and businesses.
Genetically modified food has been on the market since the early 90’s and since that time has attracted both positive and negative attention. Many people believe genetically modified food to be unsafe for human consumption and a hazard to the natural environment. There have been numerous studies undertaken to determine the risks involved with genetically engineering foods. As yet no set conclusions have been reached about the risk involved with genetically engineered food and strict guidelines have been established to regulate the genetically modified foods that can be sold to the consumer.
Coal fired power is created by burning coal in a large furnace to boil water. The stem from the boiling water is used to turn a large turbine at high speeds. The turning turbine is connected to a generator which consists of a large copper wire surrounded by magnets. As the wire passes the magnets they create a strong magnetic field. The wire spinning through the magnetic field creates electricity which is stored and then transferred via electrical wiring. The steam used to turn the turbine is then cooled and redirected back to the furnace where it is boiled again to make steam.
Nuclear power is generated from a metal called uranium. Uranium is mined in places such as Australia, Argentina, Canada, Brazil, China, France and many other countries. The uranium is used to create controlled nuclear reactions called nuclear fission. Nuclear fission gives off a tremendous amount of heat which is used to heat water to create steam. This steam turns turbines which produces electricity. In a standard fossil fuel electricity station the same thing occurs except the burning of the fossil fuel heats the water to create steam. Nuclear power plants can produce more energy using less fuel and thus they are seen as a more environmental friendly source of power.
A few days ago, I wrote a post titled ‘what are GM foods‘. Today, I am going to look at all the advantages of growing genetically modified foods.
Advantages (Pros) of Genetically Modified (GM) Foods:
- Saves the use of toxic chemicals. GM crops can be made resistant to pests, so pesticides do not need to be sprayed on them. This is also better on
