Agriculture as a system

Agricultural enterprises-crop or livestock-deal with such concepts as labor supply, marketing, finances, natural resources, genetic stock, nutrition, equipment, and hazards. While it is possible to effectively manipulate each mechanism of successful farming individually, better results can often be obtained by treating the farming operation as a system. The interactions, then, among system components may become more important than how each component functions by itself. Treating production operations holistically offers greater management flexibility, provides for more environmentally and economically sound practices, and creates safer and healthier conditions for workers and for farm animals. NIFA staff provides leadership to land-grant university partners and other grantees as they conduct research, education, and extension activities in programs related directly and indirectly to agricultural systems.

Oil: for and against

Oil is a type of fossil fuel created naturally and are deposited underneath the earth’s surface. Oil are use to generate energy through a process call combustion to generate heat. All fossil fuels are non-renewable, which mean oil will run out.

Ever since the beginning of the Industrial Revolution, Energy from fossil fuels such as oil had been one of the main sources of energy. Oil is widely available, generating energy with oil require direct combustion and the problem is the byproducts of the combustion of oil have a negative impact on the environment.

Oil pros:

• No other energy source can move vehicles with greater speed at longer distances than oil.
• Create jobs for the local economy.
• Use in cars, convert into electricity,plastics, wax, sulfur, asphalt.

Oil cons:

• Oil is non-renewable, which mean it will eventually run out.
• Burning oil pollute the environment by releasing CO2 and other toxic.
• Burning oil releases green house gases, which contribute to global warming.
• Oil companies need to build big oil rigs to extract oil offshore and inshore.
• Oil leaks may occur which result in environmental disaster by killing wild life, disturbing the biodiversity of that area and it take years for cleanup.
• Extracting oil from sand takes a lot of water.
• Drilling for oil is unpredictable; it takes a lot of time to search for oil.
• It is expensive and dangerous to transport oil.
