Sustainability refers to the ability to meet the needs of the present without compromising the ability of future generations to meet their own needs. It involves using natural resources in a way that ensures their availability for future generations, while also taking into account social, economic, and environmental factors.
Some of the challenges to achieving sustainability include overconsumption, pollution, climate change, and social inequality. Solutions involve implementing policies and practices that promote renewable energy, sustainable agriculture, conservation of natural habitats, and equitable access to resources.
