"Half-Earth" is a concept proposed by biologist Edward O. Wilson that suggests we should dedicate half of the Earth's land and sea to nature. This idea aims to protect biodiversity and ensure that various species can thrive without human interference. By setting aside large areas for wildlife, we can help combat the ongoing extinction crisis and preserve ecosystems that are vital for our planet's health. The goal of the Half-Earth initiative is to create a sustainable balance between human activities and the natural world. By conserving half of our planet, we can maintain essential resources, such as clean air and water, while also allowing future generations to enjoy the beauty and diversity of nature.
