Global Issues: Gender Equality and Women’s Empowerment

Gender equality means that men and women have equal power and equal opportunities for financial independence, education, and personal development. Women's empowerment is a critical aspect of achieving gender equality. It includes increasing a woman's sense of self-worth, her decision-making power, her access to opportunities and resources, her power and control over her own life inside and outside the home, and her ability to effect change. Yet gender issues are not focused on women alone, but on the relationship between men and women in society. The actions and attitudes of men and boys play an essential role in achieving gender equality.

Education is a key area of focus. Although the world is making progress in achieving gender parity in education, girls still make up a higher percentage of out-of-school children than boys. Approximately one quarter of girls in the developing world do not attend school. Typically, families with limited means who cannot afford costs such as school fees, uniforms, and supplies for all of their children will prioritize education for their sons. Families may also rely on girls' labor for household chores, carrying water, and childcare, leaving limited time for schooling. But prioritizing girls' education provides perhaps the single highest return on investment in the developing world. An educated girl is more likely to postpone marriage, raise a smaller family, have healthier children, and send her own children to school. She has more opportunities to earn an income and to participate in political processes, and she is less likely to become infected with HIV.

Women's health and safety is another important area. HIV/AIDS is becoming an increasingly impactful issue for women. This can be related to women having fewer opportunities for health education, unequal power in sexual partnership, or as a result of gender-based violence. Maternal health is also an issue of specific concern. In many countries, women have limited access to prenatal and infant care, and are more likely to experience complications during pregnancy and childbirth. This is a critical concern in countries where girls marry and have children before they are ready; often well before the age of 18. Quality maternal health care can provide an important entry point for information and services that empower mothers as informed decision-makers concerning their own health and the health of their children.

A final area of focus in attaining gender equality is women's economic and political empowerment. Though women comprise more than 50% of the world's population, they only own 1% of the world's wealth. Throughout the world, women and girls perform long hours of unpaid domestic work. In some places, women still lack rights to own land or to inherit property, obtain access to credit, earn income, or to move up in their workplace, free from job discrimination. At all levels, including at home and in the public arena, women are widely underrepresented as decision-makers. In legislatures around the world, women are outnumbered 4 to 1, yet women's political participation is crucial for achieving gender equality and genuine democracy.

Read the following passage about green living and mark the letter A, B, C, or D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30

          Green living refers to a lifestyle that promotes sustainability and environmental consciousness. This way of life encourages individuals to make choices that reduce their carbon footprint and conserve natural resources. Practices such as recycling, using renewable energy sources, and reducing waste are fundamental aspects of green living. By adopting these practices, individuals can contribute to the preservation of the environment and promote a healthier planet for future generations.

          One significant component of green living is the use of renewable energy sources. Solar, wind, and hydroelectric power are examples of renewable energy that can replace fossil fuels. Using renewable energy reduces greenhouse gas emissions and dependence on non-renewable resources. Additionally, renewable energy sources are often more sustainable and have less impact on the environment.

          Another important aspect of green living is sustainable consumption. This involves choosing products that are environmentally friendly and responsibly sourced. For example, buying locally produced food reduces the carbon footprint associated with transportation. Moreover, opting for products made from recycled materials helps conserve resources and reduce waste.

          Green living also emphasizes the importance of conserving water and energy. Simple actions such as turning off lights when not in use, fixing leaks, and using energy-efficient appliances can significantly reduce energy and water consumption. These practices not only benefit the environment but also save money on utility bills.

          Education and awareness play a crucial role in promoting green living. By educating individuals about the benefits of sustainable practices and how to implement them, communities can foster a culture of environmental responsibility. Awareness campaigns, workshops, and educational programs are effective ways to encourage people to adopt green living practices.
