Goal 7 aims to ensure environmental sustainability through four targets: reversing loss of environmental resources, reducing biodiversity loss, improving sanitation and access to clean water, and improving lives of over 100 million slum dwellers. The author believes this goal is important because the environment has deteriorated with endangered animals, fires, and other harms. As humans, we risk extinction if we do not improve our habitat. Locally, communities can work together on projects like planting trees, driving green vehicles, and avoiding plastic to contribute. The greatest individual contribution is to be aware of environmental issues and make green choices in transportation and living. Social media can help by sharing links to donate or volunteer with organizations working on environmental sustainability.
