Exhaustible:
These can be maintained by the methods man uses them:
(a) Renewable:
The living or dynamic resources whose, perpetual harvest is dependent upon proper planning and management by man. These are:
(i) Water in place
(ii) Soil fertility
(iii) Products of the land—agricultural products, forests, forage land, wild animals
(iv) Products of lakes, streams and impoundments—freshwater fish, black bass, lake trout, catfish
(v) Products of oceans—marine fish, marine mammals
(vi)Human resources
(b) Non-renewable:
Once exhausted, there is no hope of replacement:
(i) Mineral resources
(ii) Fossil fuels
(iii) Species of wildlife
In general, the concept of conservation evolved mainly for non-renewable resources but for renewable resources proper management is also necessary.
