Asked in Human Origins
Can human beings use the earth anyway they want?
To the question "Can human beings use the earth any way they want" the answer is yes. However, if you rephrase the question to "Should human beings..." the answer is a resounding NO. While the Earth continues to astound us with its ability to heal itself, Earth is not an unlimited resource. The natural resources should be used sparingly and recycled judiciously to ensure it will be available for our descendants.
Asked in Technology
Should be current in earth pin yes or no and why?
No, because electrical systems use earth as a reference of zero potential, however lots of electrical appliances use the earth as a reference point and dump a small amount of current to earth all the time in order to limit power spikes which can damage micro electronics, as long as the earth pin has good contact with the main earth terminal in an electrical installation this is not a problem. some larger appliances like water heaters and electric oven also leak current to earth while they are in use. This is another reason why there should always be a good contact with the main earth terminal.
