Green belts refer to areas of land that are designated for natural vegetation, urban agriculture, or recreational activities, and usually lie outside or on the fringes of urban areas. The antonyms for green belts are areas of land that are urbanized, industrialized or built-up. These lands may lack natural vegetation, and instead are covered with concrete, tar, or buildings. They can hinder or even destroy the ecosystem, have negative impacts on human health, and contribute to climate change. Green belts, on the other hand, provide numerous benefits including reducing carbon emissions, regulating local climates, promoting biodiversity, improving air and water quality, and enhancing human wellbeing. Therefore, it is crucial that we protect and invest in green belts to ensure a sustainable future for ourselves and the planet.
