The media is very influential and can raise important environmental issues that can influence the thought process of consumers (Holbert et al., 2003); possesses the power to influence the social norm (McQuail, 1987). Communication campaigns conducted through various media sources have been found to positively influence consumers' recycling behavior (Mee and Clewes, 2004). Mass media has been found to influence young consumers' perception and preference towards various products (McNeal and Ji, 1999). Recently, Lee (2014) found that environmental messages disseminated through the media influence consumers' purchasing behavior towards sustainable products. Say no to plagiarism.

Get an Original Essay Social Influence Social influence can be explained as a state in which someone meets another's expectations or considers information acquired from another as a sign of reality (Deutsch and Gerard, 1955). Gupta and Ogden (2009) found that most green consumers had a high level of trust in others and expected others to also adopt green behaviors. Therefore, consumers often purchase green products to show society their ecological concern. In many studies, social groups and subjective or social norms have been found to have a positive correlation with purchase intention and actual purchase of green and other ethically produced products (Eze and Ndubisi, 2013; Vermeir and Verbeke, 2006). ecological characteristics of the product and strengthens confidence in the product's environmental claims (Rios et al., 2006; Ip, 2003). Eco-labeling can help marketers differentiate their offerings in the consumer's mind and have a positive effect on consumers' decision-making regarding product purchase, thus increasing the sale of the company's offerings (Bougherara and Piguet , 2009). It has been found that environmentally conscious customers prefer eco-labeled products (Mohan Das Gandhi et al., 2006). Previous studies suggest that an eco-label motivates the consumer to purchase eco-friendly products (Harris, 2007; Rahbar and Wahid, 2011; Young et al., 2010). Parent Parental influence is seen as a socialization factor in the adolescent phase. Parents' consumption habits, attitudes and intentions to purchase a product strongly influence the consumption pattern of young people. Furthermore, parents who have a strong desire to consume material goods, their children also value material goods similarly to their parents (Chaplin & John, 2010, p. 176). In a study by Caruana & Vassallo (2003, pp 55,61) they found that parental influence on purchasing behavior plays a main role for children. They also found that family members with one or more children have different levels of parental influence on their purchasing decisions. Cotte & Wood, (2004, p. 84) found that parental influence not only exists in the purchasing decision-making process but also shapes young children's behavior. For example, parents' creativity and innovative spirit also encourage their children to think creatively. The study also found that a youngadult adopts the same similar behavior that his parents maintain in their style and socialization process. PeerPeer relationship is a dominant factor in adolescent decision making. Relationship between adolescents formed in early childhood considered weak. Relationships in the adolescent phase become more influential, intimate and strong (Berndt, 1982). A study conducted by Gavin & Furman in 1989 found that people place more value on the teenage period. In the period of early and middle adolescence, people emphasize the need to become members of popular groups that hold similar opinions and thoughts compared to those in different stages of adolescence. Moschis and Churchill (1979, p. 45) found different results in their study. They found that older adolescents are more knowledgeable about products and services and are able to independently differentiate positive and negative information from advertising. In a study conducted among younger adolescent girls and peer influence on fashion product purchasing decisions a strong correlation was found between these two. Peer influence plays a key role in choosing fashion products, especially for teenage girls. These teenage girls also value the opinions of their older sisters who are very close with them. Younger adolescents do not even bother paying premium prices if their peers certify that fashion products are cool (Grant & Stephen, 2006, p. 110). Another study on the consumption pattern of snacks and soft drinks by young consumers shows a positive relationship between peer influence and their purchasing behavior (Wouters et al., 2010). A study conducted on young adolescents' motivation and achievement in the context of peer influence found similar results to other studies. He found that a young adolescent was influenced by the beliefs and behaviors of his peers at his developmental stage (Ryan, 2001, p. 1145). Perceived Price Price is a significant variable that can be used to predict consumers' purchasing intentions for organic. Consistent with Magnusson et al. (2001), organic products are invoiced at a slightly higher price. This has been considered the main cause of consumers' inability to develop positive purchase intentions towards organic food products (Magnusson et al., 2001; Al-Sabbahy et al., 2004). Further research suggests that consumers tend to have positive purchase intentions for products from which they can get value for their money (Padel & Foster, 2005). Interestingly, Lockie et al. (2002) argued that pricing often conflicts with other motivations, such as environmental concern: a consumer may be willing to demonstrate that he or she cares about the environment, but the price premium may discourage him or her from developing purchase intentions. positive for organic foods (Effendi, Ginting, Lubis & Fachruddin, 2015; Gan, Wee, Ozanne & Kao, 2008). Interestingly, premium prices for organic foods do not always lead to negative purchase intentions. There is evidence to support the idea that a number of consumers tend to use price as a signal to indicate higher product quality. Consumers can use the price indication to distinguish whether the product is organic or conventional. However, it is counterintuitive for organic food to be priced less than or the same as conventional food (Byrne, Toensmeyer, German & Muller, 1991). It can therefore be expected that higher prices can positively influence the probability of purchasing organic foods (Lichtenstein et al., 1988;, 2011).
