Answer:
If the Earth is under threat all life forms that inhabit the planet are in danger. Many of man’s activities have caused disturbance to the Earth and its environment. Many natural systems that sustain life on Earth have been affected in the process. Global warming and climate change are a consequence of such disturbances.
Deforestation, building of dams across rivers, clearing of natural habitats of wildlife, as also air and water pollution have all adversely affected the natural equilibrium on Earth, causing threats to all life forms including man. We need to protect life on Earth by protecting Planet Earth.
