What can we do to protect wildlife resources so they will be around for future generations? nothing–wildlife resources are renewable and will eventually replenish themselves
harvest fast-growing trees, impose fishing limits, and impose laws to prevent poaching and illegal hunting
not use wildlife resources–they are nonrenewable and cannot be replaced
not allowing fish farming, selected harvesting of younger trees, and laws that do not put a limit on hunting

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
