1. Career. More than 25% of the work force of the world is engaged in professions related to botany – agriculture, farm scientist, horticulture, forester, bacteriologist, microbiologist, pure research scientist, teacher, etc.
2. Curiosity. There are several types of plants found in our surrounding and spots we happen to visit. The plants attract our attention due to their majestic shape, foliage, flowers, fruits, smell etc. Everybody wishes to know the cause of floods and soil erosion. All these can be satisfactory explained only with the knowledge of botany.
3. Pollution. Human wastes, farm wastes, other types of organic debris, factory effluents and smoke are the major sources of pollution. They have both immediate and long term effects. The knowledge of causes of pollution, effects of pollution and methods of reducing or eliminating it are of great importance. For example, all types of organic waste can be used to produce fuel gas as manure. This reduces pollution drastically and prevents the multiplication of several pathogens. Similarly, the harmful gases from factory smoke are known to be absorbed by a number of plants. A good growth of such pollution-decreasing plants around industrial estates shall, therefore, keep the environment clean and healthy.
4. Natural Resources. Coal and petroleum are non-renewable natural resources while forests are renewable natural resource. The reserve of coal and petroleum are limited. They should be used very judiciously so that they may last for several decades. Forests can be made to last forever. They are the source of fuel wood, timber, wood pulp, rubber, drugs, gums, resins, lac, turpentine, etc. Forests protect us from floods. They make the weather precaution for maintaining the forest wealth is to keep a balance between exploitation and regeneration. However, pressure on forest land for cultivation, destruction of plants for fuel and by overgrazing has caused a sharp decline in forested area in Nepal (40% Bajracharya, 1984).
5. Population Growth. Population of the country is rising. However, land available for cultivation is limited. In order to feed the growing population, ways and means have to be discovered to increases food availability and reduce population growth. Since, more land cannot be made available for agriculture, the productivity of crop plants must be increased through development of high yielding and short duration plants. It requires a coordinated effort from several quarters like plants breeder, plants physiologist, plants pathologist, soil scientists, etc.
6. Modern and Healthy living. Botany and allied sciences have helped remove many superstitions about diseases and causes of human miseries like floods and famines. The knowledge has helped us to plan not only for the present but also for the future generations. We are now more aware to have healthy and pleasant surroundings, nutrition, diseases and their remedies. Keen-ness to struggle, to achieve and live amicably are other useful lesson obtained from botany and allied sciences.
