Answer 2

Over exploitation or over-harvesting of a plant or an animal species reduces the size of its population leading to its extinction. Over-exploitation is one of the major causes threatening global biodiversity. Steller's sea cow (Hydrodamalis gigas) was a large, herbivorous, marine mammal (largest member of the order- Sirenia) which had been discovered in $1741$ and became extinct by $1768$. It is one of the few megafaunal mammal species to have died out during the historical period. It was over harvested for food, for skin, for its valuable subcutaneous fat, etc.
