Top causes of species extinction

Natural causes include climatic changes such as climatic heating or cooling, change in sea level and currents, disease or epidemic, and in rare cases acid rain.

Other Human causes incude habitat fragmentation, Agriculture, Human overpopulation, Deforestation and Hunting or poarching.

Climatic changes causes temperatures to increase or decrease drastically which inturn impacts life of animals. Aquatic life is highly dependant on sea level, sea current and gases from volcanic activty change the composition of ocean water making aquatic life impossible in such water conditions. Disease/epidemic is another major cause for extinction. Due to some major diseases there have been continuous death of certain species eventually leading to extinction.

Human causes of extinction have emerged recently which include events like deforestation, hunting/poarching, agriculture, habitat fragmentation and overpoplation.

Habitat fragmentation is one of the leading causes of extinction, loss of habitat or animals finding destroyed homes either due to human activities or natural clamities is causing the survival to be difficult for animals and birds. Growing human population is another major cause of extinction. For example, florida panther, Loggerhead sea Turtle, , Atlantic blue fin tuna, Mississippi frog, polar bear, and Gulf sturgeon have been noted as being under serious threat due to mass human population growth. These animals are rapidly loosing their habitat due to human population increase which is increasing human activities and occupying free lands for human occupancy and use of forest resourses for human lives.

Deforestation, which has reasons mainly related to money or people\'s needs have made many species homeless. Removing trees removes most of the canopy, which blocks sun’s rays and holds heat at night. Deforestation leads to increase in extreme temperatures causing harm to plants and animal species.
