IMHO there are 2 big areas - moving heavy industry off earth and seeding life elsewhere to protect it.
Moving the industry would allow unlimited expansion of manufacturing capacity with no ecological regard. This would basically ensure paradise on earth as long as population is kept at optimal level. In addition it would enable advancement of mega scale projects like o'neill cylinder and generation ships to safeguard humanity from catastrophic events on earth.
