Renewable and non-renewable resources
Environmental resources are the primary sources
Environmental resources are the primary sources for the existence of humans. These resources are either renewable or non-renewable. Air, water food, land, forests and wild life are renewable resources because they are never depleted. they are recycled in nature. Non-renewable resources include various metals, non-metallic minerals and fossil fuels (coal oil and natural gas). these resources are exhaustible and once consumed cannot be replaced. In nature, there is no such thing as waste; dead materials decay and become food for other living things. this food is consumed, or decays and becomes food again. this is the nutrient cycle, the process that supplies food to living things. The balance in the nutrient cycle can be upset when : (1) not enough food is produced, (2) too much food is consumed, (3) decayed nutrients are not returned to the ground. all the resources necessary for life form a part of natural cycles. these cycles have no beginning and no end. the driving force behind all of these cycles is the sun. the earth is a self-sustained unit. we are in our own space ship. there is no chances of bringing in more resources. we have to use wisely what we have.
