The introduction is a preliminary part of a book, musical composition, or the like. It gives the overall information on the subject matter under the discussion either in chronology or at the definite moment of time. In other words, this is the invitation into the issue that will be analyzed thoroughly further in the paper. Hence, the introduction part of the dissertation is a leading up to its main part.
The sample dissertation introduction below offers the example of this type of paper on the matter of the resource conservation.
The resource conservation is a modern global problem of humanity, which is primarily concerned with the limitation of the most important organic and mineral resources of the planet. The scientists warn about the possible exhaustion of the known and available for use oil and gas reserves as well as about the depletion of other key resources: iron and copper ore, nickel, aluminum and chromium. Oil and gas have become the main sources of energy and, at the same time, the important raw materials. This explains the ever-increasing exploitation of oil and gas fields.
At the moment, the mankind faces a question on how long these natural resources will be available. It is obvious that the earth’s resources are exhaustible. Today, there is a shift to the less productive mines of raw materials or those, which are located in some remote areas with snowy natural conditions. However, that fact considerably increases the cost of production. Thus, the division of natural resources into inexhaustible and exhaustible becomes conditional. Besides, the scientists already think about the possibility of the exhaustion of the atmospheric oxygen and, what is more, the same issue may arise as to the solar energy resources in the future, even though it seems impossible for the time being.
Taking all mentioned above into consideration, one should expect that, at least, in the next decade, there will be the further growth in demand as for a wider variety of the natural resources. While assessing the stocks, it is important to distinguish between two groups of the resources: nonrenewable and renewable. The first ones are able either to reproduce (the biological resources) or continuously come to Earth from the outside (solar energy) or be continuously reused (water). Meanwhile, the renewable resources, as well as non-renewable, are not infinite, even though their renewable portion can be used continuously. The number of the second ones decreases steadily due to their utilization. They include mineral and land resources, and the limited size of the area of the earth’s surface as well.
If one looks at the main types of the world’s natural resources, there appears the next situation. Such mineral fuels as oil, gas, coal are still the main types of energy. These energy sources are not renewable and, at the current rate of growth of their production, it is possible that they will be exhausted in 80-140 years. However, the share of these sources should be reduced due to the development of nuclear energy based on the use of heavy fuel isotopes of uranium and thorium. Nevertheless, even these resources are not renewable. For instance, uranium stocks are expected to be available only for a century.
All kinds of the natural resources – heat, water, mineral, biological, soil – are associated with the certain components of the natural complex (geosystems) and comprise an expendable part of these components. Ir is the ability to be expended, which is a specific feature of the natural resource distinguishing them from their natural environment. The latter includes the permanent property of natural systems that are not used to produce a useful product, however, have a significant positive or negative impact on the development and location of the production (for instance, temperature and water regime, the winds, the relief, the bearing capacity of soils, permafrost, seismic). In the contemporary world, there are both economic and technical problems associated with the extraction of raw materials. The most urgent, however, is the lack of knowledge of the real data about how many resources are left.
The waste recycling, economical use of water (desalination of seawater, the use of icebergs), the transition to a more durable and lightweight materials (CFRP) are the possible ways out of the situation. The supporters of the environment call for industrialized countries to shift from the single-use with a lot of waste to the farm by the production with less amount of waste. This requires the involvement of the economic incentives and the certain actions from the side of both governments and people as well as changes in the behavior and lifestyle of the world’s population.
