IntroductionSustainabilitySustainability means the activity of something that lasts a lifetime. Sustainability is the condition in which nature and humans can coexist at the same time and create harmony, without destroying each other. To sustain humans it is necessary to satisfy their needs using nature's resources. (By Johann Dreo, March 9, 2006) (1) In this figure, we can explain that everything must be in the right proportion, whether it is society, the environment or the economy. , otherwise the world's resources will become extinct.Marketing conceptMarketing is an activity through which the producer provides information about the goods he has produced and the buyer can know the product he is purchasing.We are the other typeWe are the type that gives people what they know they really need, not what we think they should want(T.pratchett, Witches Abroad)(2)There are basically three main terms to understand marketing1. Target markets2. Marketing strategy3. Marketing mix1. Target Market The target market is basically a normal market. It is for a group of customers for which a company decides its marketing objective. Target markets are of the following types such as geographic segment (e.g. climate, location), demographic segment (e.g. gender, age, income) and many more. For example. If a toothpaste company wanted to produce a toothpaste for children aged 3 to 10 years, then they will have a toothpaste with a jelly taste and they will definitely advertise it through a cartoon so that children will be attracted to the advertisement.2. Marketing StrategyMarketing strategy is a process that can enable an organization to focus its resources on optimal opportunities with the aim of increasing sales and reaching a sufficient base of employees, who are highly loyal to the company and are helpful to consumers in any way. The company should consider the following points to uphold in the perfect competitive market: • Address the needs of consumers and provide people with knowledge about the things they are buying. • Development of the company making the strategic move. • Respond to government rules and regulations and influence the policy agenda. • Provide the good quality of the product to the consumer. So we can conclude that to sustain a perfect or real world competitive market as we say, the company must have the ability to change with the market conditions to survive in the real world. Someone rightly said “It is not the strongest species that survives, nor the most intelligent, but the one most responsive to change”. (Charles Darwin)(11)
