Child activists are young individuals who advocate for social, environmental, or political change. They often raise awareness about issues that affect their communities, such as climate change, education, and children's rights. By using their voices and creativity, they inspire others to take action and make a difference. Many child activists have gained international recognition for their efforts. For example, Greta Thunberg has become a prominent figure in the fight against climate change, while others focus on issues like gender equality and mental health. These young leaders demonstrate that age does not limit the ability to create positive change in the world.
