Space Garbage
"More than 27,000 pieces of orbital debris, or “space junk,” are tracked by the Department of Defense’s global Space Surveillance Network (SSN) sensors. Much more debris -- too small to be tracked, but large enough to threaten human spaceflight and robotic missions -- exists in the near-Earth space environment."

Ocean Garbage
"Nearly 513 million tons of plastics wind up in the oceans every year out of which 80% is from just 20 countries in the World. While China, India and America are in the list of contributors to this havoc, other countries like Indonesia, Philippines, Vietnam, Sri Lanka, Thailand, Egypt, Malaysia, Nigeria, Bangladesh and South Africa contribute their own share in a considerable manner. According to a recent research, the top 5 polluters are China, Indonesia, Philippines, Vietnam and Sri Lanka."
