Natural resources on Earth

Natural resource or natural capital is the planet’s air, water, soil,wildlife, mineral and natural purification , recycling, and pest controlprocesses. Solar capital is the energy from the sun.

Natural resources are:

   * Air, water and soil
   * Biological resources - plants and animals
   * Raw materials (like minerals)
   * Space and land
   * Wind, geothermal, tidal and solar energy

Natural resources are often classified into renewable, flow, and non-renewable resources.

Ecological resource- is anything required by organisms like you for normal maintenance,growth and reproduction.Examples are water,shelter, food, and habitat.Ecological resources include fish and wildlife populations, habitats, and their relationships to each other and the environment/ecosystem.

Economic resource- is anything obtained fromthe environment to meet your needs and wants. Examplesare food, water, shelter,manufactured goods,transportation,communication and recreation.

We have a lot of resources to meet our needs. Some of these resources are finite.Other resources are renewable but it takes time to replace or replenish them. Unfortunately,the rapid consumption of these raw materials by our expanding population has led to the exploitation of the natural resources. Exploitative attitudes of humans rapidly reduce theavailability of natural resources.
