What is Conservation?

Hint: Earth's natural resources include air, plants, soils, water and wildlife. Conservation can be done by care and protection of the resources. It includes maintaining diversity of species, genes, and ecosystems as well as function of the environment, such as nutrient cycling.

Complete answer:
We know that Earth's natural resources include air, plants, soils, water and wildlife. Conservation is the care and protection of these resources so that they can persist for future generations. Conservation is similar to preservation, but while both relate to the protection of nature, they strive to accomplish this task in different ways. Conservation seeks the sustainable use of nature by humans, for activities such as hunting, logging , or mining, while preservation means protecting nature from human use.
This difference is illustrated by how countries manage their public lands. The goals of national parks, for instance, is preservation with an emphasis on causing minimal change to the landscape or environment, meanwhile national forests can be used for cattle grazing, lumber, hunting, and recreation.
Continued human population growth has led to unsustainable rates of consumption of our natural resources, resulting in a loss of Earth's biodiversity. The factors which account for loss of biodiversity are habitat destruction, climate change, invasive species, over exploitation, and pollution. Declining biodiversity is closely intertwined with species extinction.

Note:
Scientists estimate that current extinction rates are about a thousand times higher now than would be expected based on the fossil records and that we may be experiencing a mass extinction event, which is when 75 percent or more species are lost at a time.
