Many people in our community may face challenges in their environment such as the elderly, those who are discriminated against, and the disabled. For the elderly, they may find it hard to do some of the things that the used to be able to do as they have aged. Many people also think that they are a burden to the society since the government has to pay pensions and bonuses to them each month. The tax payers will then find them a bother and treat them badly. People have stereotypes and think that they receive less education and are not smart, resulting in discrimination. Another group of people that often faced challenges in their environment are people whom are not part of majority, for example a different ethnic group. They are often seen as different and many would make fun or discriminate them,  pointing out their difference to make them feel bad even though there is actually nothing to be ashamed about. Lastly, the disabled often face challenges in their environment. Those physically disabled would have difficulty moving from place to place, while those mentally challenged are often seen as unsound for they have different thinkings compared to majority. Even though they did not want to be disabled either physically or mentally, many in their environment are still unable to accept them and therefore exclude them or sometimes even mock them. 

1) People with disabilities, elderly people living alone, minority races, single parents, people with mental illnesses, working class or underclass citizens - generally people who do not fit into what our society perceives as the 'social norm'

2) Others might discriminate against them, or segregate them because they are in different situations from the majority, the middle class citizens. The discrimination could be through many forms, and harm these people in various ways. Some people may also pity them for their situations, which would make them feel embarrassed. 

3) Misconceptions and stereotypes that develop and stick around over time due to the no or little awareness raised about these people, and how they may not be living a life as sad as we paint them to be, or that even if they are staying in less fulfilling living conditions, they are not for us to pity or make fun of.
