At different points on the planet, the geography, climate and altitude are all varied. Due to differences in these characteristics, there is an unequal distribution of resources around the globe. Furthermore, all of these characteristics differ from one location to the next on the planet. Also, the distribution is determined by the level of development and technological advancement.
Conservation is the process of preserving resources for future generations. It is the ethical use and protection of important resources such as minerals, water, trees, and wildlife. The goal of resource conservation is to preserve the natural world in order to conserve the sources of resources.
Humans are significant as a resource because they can extract value from all other resources. They have the knowledge, talent, and technology to make the best use of nature to generate more resources. Humans become more valuable as a resource as a result of education and health.
