Introduction:
Human wants are unlimited and can never be satisfied completely. These wants can be categorized into two types, namely, primary wants and secondary wants. Primary wants are the basic needs required for survival, while secondary wants are luxuries that enhance the quality of life. These wants are satisfied primarily by nature, and this statement can be justified in multiple ways.

Nature provides essential resources:
Nature is the primary source of resources that humans require to satisfy their wants. For instance, air, water, and food are essential resources that humans require to survive. These resources are provided by nature, and without them, humans cannot survive. Trees and plants provide oxygen, food, and shelter to humans and wildlife, which is an important aspect of nature.

Nature provides raw materials:
Nature provides raw materials that are used to produce goods and services to satisfy human wants. For instance, forests provide timber, which is used to make furniture and paper. Similarly, minerals and ores are extracted from the earth to make metals, which are used to make tools and machinery. Without these raw materials, humans cannot produce goods and services that satisfy their wants.

Nature provides energy:
Nature provides various sources of energy, such as solar energy, wind energy, and water energy. These sources of energy are used to power machines and equipment that are used to produce goods and services that satisfy human wants. For instance, solar energy is used to power homes, offices, and factories, while wind energy is used to generate electricity.

Nature provides recreational opportunities:
Nature provides recreational opportunities that enhance the quality of life. For instance, hiking, camping, and fishing are recreational activities that are enjoyed by many people. These activities provide an opportunity for people to connect with nature and enjoy its beauty.

Conclusion:
In conclusion, human wants are satisfied primarily by nature. Nature provides essential resources, raw materials, energy, and recreational opportunities that are required to satisfy human wants. Without nature, humans cannot survive, and their wants cannot be satisfied. Therefore, it is essential to protect and conserve nature for the benefit of present and future generations.
