                                            Evolutionary biology
1. Evolutionary biology is a sub-field of biology concerned with the origin of species from a common descent and descent of species, as well as their change, multiplication and diversity over time. Someone who studies evolutionary biology is known as an evolutionary biologist. To philosopher Kim Sterelny, «the development of evolutionary biology since 1858 is one of the great intellectual achievements of science».
2. Evolutionary biology is an interdisciplinary field, in that it includes scientists from a wide range of both field and lab oriented disciplines. For example, it generally includes scientists who may have a specialist training in particular organisms such as mammalogy, ornithology, or herpetology, but use those organisms as case studies to answer general questions in evolution. It also generally includes paleontologists and geologists who use fossils to answer questions about the tempo and mode of evolution, as well as theoreticians in areas such as population genetics and evolutionary psychology.
3. Findings from evolutionary biology feed strongly into new disciplines that study mankind's sociocultural evolution and evolutionary behavior. Evolutionary biology's frameworks of ideas and conceptual tools are now finding application in the study of a range of subjects from computing to nanotechnology. It also contributes to the field of evolutionary medicine.

                                     Scope and importance of botany
1. In biology, plant life can be studied from different perspectives, from the molecular, genetic and biochemical level through organelles, cells, tissues, organs, individuals, plant populations, and communities of plants. At each of these levels a botanist might be concerned with the classification, structure (anatomy and morphology), or function (physiology) of plant life.
2. Historically all living things were grouped as animals or plants, and botany covered all organisms not considered animals. Some organisms once included in the field of botany are no longer considered to belong to the plant kingdom – these include fungi (studied in mycology), lichens (lichenology), bacteria (bacteriology), viruses (virology) and single-celled algae, which are now grouped as part of the Protista. Paleobotanists study also ancient plants in the fossil record. It is believed that early in the Earth's history, the evolution of photosynthetic plants altered the global atmosphere of the earth, changing the ancient atmosphere by oxidation.
3. The study of plants is vital because they are a fundamental part of life on Earth, which generates the oxygen, food, fibres, fuel and medicine that allow humans and other life forms to exist. Through photosynthesis, plants absorb carbon dioxide, a greenhouse gas that in large amounts can affect global climate. Additionally, they prevent soil erosion and are influential in the water cycle. A good understanding of plants is crucial to the future of human societies as it allows us to produce food to feed an expanding population, to understand fundamental life processes, to produce medicine and materials to treat diseases.

                                                     A forester
1. A forester is a person who practices forestry, the science, art, and profession of managing forests. Foresters engage in a broad range of activities including timber harvesting, ecological restoration and management of protected areas. Foresters manage forests to provide a variety of objectives including direct extraction of raw material, outdoor recreation, conservation, hunting and aesthetics.
2. A forester is also a title used widely during Medieval times. The forester usually held a position equal to a sheriff or local law enforcer. He was responsible for patrolling the woodlands on a lord or noble's property. His duties included negotiating deals for the sale of lumber and timber and stopping poachers from illegally hunting. Many times wanted criminals would hide in a forest. When this occurred it was the duty of the Forester to organize armed gangs to capture the criminal. Often foresters held titles of prominence in their local communities, and acted as barristers and arbitrators. Their pay was usually above average and they could make a decent living.
3. Many people confuse the role of the forester with that of the logger, but most foresters are concerned not only with the harvest of timber, but also with the sustainable management of forests to (in the words of Gifford Pinchot) "provide the greatest good for the greatest number in the long term". Another notable forester, Jack Westoby, remarked that «forestry is concerned not with trees, but with how trees can serve people».

1. Aeroponics is a system wherein roots are continuously or discontinuously kept in an environment saturated with aerosol of nutrient solution. The method requires no substrate and entails growing plants with their roots suspended in a deep air or growth chamber with the roots periodically wetted with a fine mist of atomized nutrients. Excellent aeration is the main advantage of aeroponics.
2. Aeroponic techniques have proved to be commercially successful for propagation, seed germination, seed potato production, tomato and leaf crops production. Since inventor Richard Stoner commercialized aeroponic technology in 1983, aeroponics has been implemented as an alternative to water intensive hydroponic systems worldwide. The limitation of hydroponics is the fact that 1 kg of water can only hold 8 mg of air, no matter whether aerators are utilized or not.
3. Another distinct advantage of aeroponics over hydroponics is that any species of plants can be grown in a true aeroponic system because the micro environment of an aeroponic can be finely controlled. The limitation of hydroponics is that only certain species of plants can survive for so long in water before they become water-logged. The advantage of aeroponics is that suspended aeroponic plants receive 100% of the available oxygen and carbon dioxide to the roots zone, stems, and leaves, thus accelerating biomass growth and reducing rooting times. Unlike hydroponically grown plants, aeroponically grown plants also will not suffer transplant shock when transplanted to soil, and offers growers the ability to reduce the spread of disease and pathogens.

                                                    Agriculture
1. Agriculture is the cultivation of animals, plants, fungi and other life forms for food, fiber, and other products used to sustain life. Agriculture was the key implement in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that nurtured the development of civilization. The study of agriculture is known as agricultural science. Agriculture is also observed in certain species of ant and termite, but generally speaking refers to human activities.
2. The history of agriculture dates back thousands of years, and its development has been driven and defined by greatly different climates, cultures, and technologies. However, all farming generally relies on techniques to expand and maintain the lands suitable for raising domesticated species. For plants, this usually requires some form of irrigation, although there are methods of dryland farming; pastoral herding on rangeland is still the most common means of raising livestock. In the developed world, industrial agriculture based on large-scale monoculture has become the dominant system of modern farming.
3. Modern agronomy, plant breeding, pesticides and fertilizers, and technological improvements have sharply increased yields from cultivation, but at the same time have caused widespread ecological damage and negative human health effects. Selective breeding and modern practices in animal husbandry such as intensive pig farming have similarly increased the output of meat, but have raised concerns about animal cruelty and the health effects of the antibiotics, growth hormones, and other chemicals commonly used in industrial meat production.
