the amounts of time children spend interacting with them, can also contribute to significant potential risk and harm to children. For example: Access to the Internet and social media is exposing children to cyberbullying, pornography and cybergrooming. Many children attend Internet cafes, computer clubs and game halls with no adequate restrictions to access or effective monitoring systems; The increasing levels of participation, particularly among boys, in violent video games appears to be linked to aggressive behaviour as the games are highly engaging and interactive and reward violent behaviour. As they tend to be played repeatedly, negative learning is strengthened and can contribute to reduced sensitivity to the pain and suffering of others as well as aggressive or harmful behaviour toward others. The growing opportunities for online gaming, where children may be exposed to a global network of users without filters or protections, are also a cause for concern. Much of the media, particularly mainstream television, fail to reflect the language, cultural values and creativity of the diversity of cultures that exist across society. Not only does such monocultural viewing limit opportunities for all children to benefit from the potential breadth of cultural activity available, but it can also serve to affirm a lower value on non-mainstream cultures. Television is also contributing to the loss of many childhood games, songs, rhymes traditionally transmitted from generation to generation on the street and in the playground; Growing dependence on screen-related activities is thought to be associated with reduced levels of physical activity among children, poor sleep patterns, growing levels of obesity and other related illnesses. Marketing and commerciali z ation of play: The Committee is concerned that many children and their families are exposed to increasing levels of unregulated commercialization and marketing by toy and game manufacturers. Parents are pressured to purchase a growing number of products which may be harmful to their children’s development or are antithetical to creative play, such as products that promote television programmes with established characters and storylines which impede imaginative exploration; toys with microchips which render the child as a passive observer; kits with a pre-determined pattern of activity; toys that promote traditional gender stereotypes or early sexualization of girls; toys containing dangerous parts or chemicals; realistic war toys and games. Global marketing can also serve to weaken children’s participation in the traditional cultural and artistic life of their community. VII.Children requiring particular attention to realize their rights under article 31 Girls: A combination of significant burdens of domestic responsibilities and sibling and family care, protective concerns on the part of parents, lack of appropriate facilities and cultural assumptions imposing limitations on the expectations and behaviour of girls can serve to diminish their opportunities to enjoy the rights provided for in article 31, particularly in the adolescent years. In addition, gender differentiation in what is considered girls’ and boys’ play and which is widely reinforced by parents, caregivers, the media and producers/manufacturers of games and toys serve to maintain traditional gender-role divisions in society. Evidence indicates that whereas boys’ games prepare them for successful performance in a wide range of professional and other settings in modern society, girls’ games, in contrast, tend to direct them towards the private sphere of the home and future roles as wives and mothers. Adolescent boys and girls are often discouraged from engaging in joint recreational activities. Furthermore, girls generally have lower participation rates in physical activities and organized games as a consequence of either external cultural or self-imposed exclusion or lack of appropriate provision. This pattern is of concern in the light of the proven physical, psychological, social and intellectual benefits associated with participation in sports activities. Given these widespread and pervasive barriers impeding girls’ realization of their rights under article 31, the Committee urges States parties to take action to challenge gender stereotypes which serve to compound and reinforce patterns of discrimination and inequality of opportunity. Children living in poverty: Lack of access to facilities, inability to afford the costs of participation, dangerous and neglected neighbourhoods, the necessity to work and a sense of powerlessness and marginalization all serve to exclude the poorest children from realizing the rights provided for in article 31. For many, the risks to their health and safety outside the home are compounded by home environments which provide no or little space or scope for play or recreation. Children without parents are particularly vulnerable to loss of their rights under article 31; children in street situations are not afforded play provisions, and are commonly actively excluded from city parks and playgrounds, although they use their own creativity to utilize the informal setting of the streets for play opportunities. Municipal authorities must recognize the importance of parks and playgrounds for the realization of the rights provided for under article 31 by children living in poverty and engage in dialogue with them in respect of policing, planning and development initiatives. States need to take action to ensure both access to and opportunities for cultural and artistic activities for all children, as well as equal opportunities for play and recreation. Children with disabilities: Multiple barriers impede access by children with disabilities to the rights provided for in article 31, including exclusion from school; informal and social arenas where friendships are formed and where play and recreation take place; isolation at the home; cultural attitudes and negative stereotypes which are hostile to and rejecting of children with disabilities; physical inaccessibility of, inter alia, public spaces, parks, playgrounds and equipment, cinemas, theatres, concert halls, sports facilities and arenas; policies that exclude them from sporting or cultural venues on the grounds of safety; communication barriers and failure to provide interpretation and adaptive technology; lack of accessible transport. Children with disabilities can also be hindered in the enjoyment of their rights if investment is not made to render radio, television, computers and tablets accessible, including through the use of assistive technologies. In this regard, the Committee welcomes article 30 of the Convention on the Rights of Persons with Disabilities which emphasizes the obligations of States parties to ensure that children with disabilities have equal access with other children to participation in play, recreation, sporting and leisure activities, including in the mainstream school system. Pro-active measures are needed to remove barriers and promote accessibility to and availability of inclusive opportunities for children with disabilities to participate in all these activities. Children in institutions: Many children spend all or part of their childhood in institutions, including, inter alia, residential homes and
