If true interplanetary and interstellar travel were achieved, would the decreasing mass of the earth become a problem?

Assuming that in the not too distant future space travel developed enough, that large numbers of ships and people were leaving the earth's surface on a regular basis. Would this ever reach a point were the amount of mass leaving the earth became dangerous?

Would the resulting decrease in mass lead to changes in the earth's orbit that in turn lead to catastrophic climate change?

Would the amount of metal leaving the earth cause changes to the gravitational filed?

Would policies need to be put in place to regulate the amount of material resources that can be shipped off planned every year?
