Ignored but critical, the link between waste and mental health is amplified in cities, where waste exposes unsustainable consumption. Cognitive-behavioral approaches can help us by exploring the connection between our thoughts, feelings, and actions towards waste, paving the way for a more sustainable future. Let's explore this link and shift our mindset for a greener tomorrow. Nessie Mwendwa is a budding social scientist passionate about mental health, environmental research, and conservation. As a counseling psychologist, she aims to use art, psychology, and love for nature to promote people's well-being, minds, and the planet. With five years of experience in waste management, Nessie is committed to contributing to policymaking and practices that ensure waste is handled as a valuable resource and biodiversity thrive alongside human beings. Her goal is to focus on the interconnectedness of things and promote positive change.
