In addition to addressing pressing global issues of resource management, sustainability, and health, the use of plants and plant-derived products can enhance food, agricultural materials, and medicine. It examines the rationale behind these solutions, which are driven by environmental imperatives such as preventing biodiversity loss and deforestation, reducing greenhouse gas emissions (up to 70% lower than those produced by animal-based systems), and offering health benefits such as lowered risks of chronic diseases and enhanced mental health through diets high in nutrients. Plant-derived materials such as natural fibers, biopolymers, oils, resins, and natural rubber are also important due to their biodegradability and industrial applications. Plant-based medicines, rooted in traditional systems, offer readily available remedies containing bioactive substances shown to be effective in treating a variety of ailments. Agricultural innovations with practical applications that increase ecosystem services, productivity, and resilience include crop diversification, agroforestry, urban farming, land restoration, and sustainable livestock integration. Despite challenges such as technological barriers, market reluctance, financial constraints, and potential ecological risks, future prospects are promising, driven by developments in gene editing, AI-driven agriculture, and policy support aligned with circular economies and the UN Sustainable Development Goals. All things considered, plant-based treatments support a transition to fair, low-impact systems that may prevent significant environmental harm while advancing human welfare and economic growth. The aim of the chapter is to provide an overview of the role of plants and plant-derived products in offering sustainable, health-promoting, and eco-friendly solutions for global challenges.
