Plenty he may not locate on the earth
so planning to book space on mars;
for up down, will have a space shuttle;
by the time we would plump double;
till my grandson will come of my age
living on this planet will be complex.
Land space would be completely filled,
we are growing two millions a week.

We must have grabbed much of land
from the woods, animals and outback.  
Enhanced populace, distorted ecology,
increased demand of water, food, energy
could lead starvation in many of parts
and extinction of animals and plants.
