Explanation

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 (Hydrodamulis 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.
