- Did the normal growth curve grow at a slower or faster pace than in the new growth curve? Did both curves level out and reach the same carrying capacity?Do you think the human species can continue raising itsglobal carrying capacity? Why or why not? Do you thinkwe should try to keep raising our carrying capacity? Whyor why not?The population of Desert Paradise (DP; a fictitious town) hasbeen doubling every 7 years. Most of the new inhabitants are“snowbirds,” people escaping the cold winters of northerlylatitudes. There are no permanent streams or lakes anywherenear DP. In fact, the only standing water occurs in the ponds ofthe many golf courses that have been built recently. The water inthese ponds needs to be replenished almost constantly, or theponds will dry up. The golf courses and yards of the suburbanstyle developments of DP all have lawns of green grass. DP hasbeen growing on a flat, sediment-filled basin between two smallmountain ranges. Much of the water supply of DP comes fromwells. What do you predict will happen to the water table of thearea in coming years, and how might the land surface change asa consequence? Might you suggest a policy to the residents ofDP that could slow the process of change?
