Different ways to preserve natural resources include reducing harvesting and consumption of resources, using renewable energy, recycling, re-using, implementing sustainable waste management systems and educating others about natural resource preservation. Development and use of technology to support these methods also help preserve natural resources.
Reducing consumption of natural resources occurs at industrial and individual levels. Industries can make production more efficient and limit harvesting of natural resources to certain areas or amounts. Individuals can make fewer purchases and limit consumption of resources in daily life. For example, an individual can choose to buy food items without plastic packaging.
Using renewable energy such as solar or wind power preserves natural resources because wind and solar are almost infinite resources while coal and oil are not. Recycling, rather than throwing items into landfills, preserves natural resources because materials are sourced from already made products rather than making items from scratch and consuming more resources. Developing sustainable waste management systems also preserves natural resources because it reduces pollution, which destroys many natural resources. Sustainable waste management can further provide more resources by rendering waste material usable for industry or individuals.
Most natural resources on Earth are limited. Preserving natural resources is a primary concern for many environmentalists concerned about the health of ecosystems and the longevity of natural resources available for human use.
