A.) Don't leave the water running while brushing your teeth and washing dishes, use a broom to clean your driveway rather than a hose, shorten your shower by a minute or take a bath instead.
B.) Plant in the fall when there's more rain to use, collect the water you use to clean your vegetables and reuse it to water your plants, avoid watering your lawn on windy days.
C.) Be aware of your water use, use sprinklers only at night and in the morning to avoid evaporation turn off the water while you wash your hair.
D.) All of the above.
D is the best answer because doing all of those things listed above are good ways an individual can conserve hundreds of gallons each month. There are also many other ways you can conserve water just by changing your habits.
How can food distribution problems lead to famine?
A.) If one place gets more food than most, then there won't be enough material to supply the rest.
B.) If food is too widely distributed, then no one will get enough food.
C.) There isn't much of a food distribution problem. We've got it down to a science.
A is the best answer, because it is a problem the world is currently facing now. Some countries are getting much more food than they actually need, while others are getting close to nothing. If we didn't give so much extra food to certain countries there would be enough to feed millions of other people in other places.
