                                     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.

Botanists study classification, structure, function of plant life while some organisms once included in its field are no longer considered to belong to the plant kingdom: fungi, lichens, bacteria, viruses and single-celled algae.
Plants role is important not only for today’s satisfaction of needs of humans and other living beings but one should also bear in mind that they can affect the future of the climate of our planet protecting air, soil and water from negative effects of a greenhouse gas.
One can hardly imagine how would it be possible for living beings to exist on the Earth without plants as they generate the oxygen, food, fibres, fuel and medicine, reduce the level of a greenhouse gas which in large amounts threatens the Earth’s climate.
Studying plants promotes people and other living beings not only to use their advantages, but also provides us with knowledge of their influence on the evolution of the Earth climate in the past and enables us to realize their importance for the future of our planet.

                                                     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.

                                                       Ecology
1. Ecology studies the distribution and abundance of living organisms, and the interactions between organisms and their environment. The habitat of an organism can be described as the local abiotic factors such as climate and ecology, in addition to the other organisms and biotic factors that share its environment.
2. One reason that biological systems can be difficult to study is that so many different interactions with other organisms and the environment are possible, even on the smallest of scales. A microscopic bacterium responding to a local sugar gradient is responding to its environment as much as a lion is responding to its environment when it searches for food in the African savanna. For any given species, behaviors can be co-operative, aggressive, parasitic, or symbiotic. Matters become more complex when two or more different species interact in an ecosystem. Studies of this type are within the province of ecology.
3. Ecological systems are studied at several different levels, from individuals and populations to ecosystems and the biosphere. The term population biology is often used interchangeably with population ecology, although population biology is more frequently used when studying diseases, viruses, and microbes, while population ecology is more commonly when studying plants and animals. As can be surmised, ecology is a science that draws on several disciplines.
