Space development requires the institution of many safeguards, not lea
st the protection of the space environment for the use of future gener
ations. The arguments concerning orbital debris are well known, but wh

he need for improved awareness of our apparent disregard for the degra
dation of this segment of the space environment and points to the inad
equacies of existing space legislation. (C) 1998 Elsevier Science Ltd.
