Conservation helps the environment to retain the natural systems that are essential to the survival of humans, plants and animals. Nutrient cycling, pollination and water purification are examples of natural systems that can be preserved through land-conservation efforts.
Greenhouse gases contribute to climate change, which can lead to devastating impacts on the environment. Plants that are necessary to an ecosystem for water purification, for example, may not adapt to the ever-warming climate and become extinct. Energy conservation can combat this problem and benefit the environment by reducing greenhouse gases to keep earth's atmospheric temperature stable and clean. In turn, keeping a stable and clean atmosphere ensures the survival of organisms that are essential to the environment.
Recycling is one way to conserve energy. Using old products to make new ones consumes much less energy than making entirely new products. That energy reduction results in less greenhouse gases being released into the environment.
Earth's limited natural resources are also preserved through recycling. For example, instead of cutting down trees to make paper products, the products can be made using old newspapers, which saves the trees that are essential to environmental ecosystems. Recycling can also help save habitats from encroachment by landfills. When goods are recycled, it reduces the trash that has to be stored on the planet.
