Transcript of Rhinos
Pros & Cons
What is the Issue?
In Africa, where many rhinos live, poachers attack and/or kill rhinos for their horns. Poachers usually dehorn rhinos when they're awake or under anesthesia, but on several occasions, they may shoot and kill the rhino for its horn. Because of this, several species of rhinos are now endangered.
Why is It Happening?
The main reasons for dehorning rhinos is for medicine or cultural use. A rhino's horn is known for treatments in Asia to rid fevers, blood disorders, and even hangovers. Either way, most poachers dehorn rhinos for money.
What are the Effects?

How Does this Relate to Ecology?
Biotic & Abiotic Factors
Rhino horns can grow back if the rhino does not die from dehorning, but it may have some psychological stress due to its dehorning
Possible extinction of several rhino species
Potential growth in vegetation
Possible medicine from horns
Money for the poachers
Possible extinction of rhinos
Cost to dehorn rhinos ($600 - $1000)
Distress for the rhinos and the poachers
Because rhinos are considered herbivores, they eat only plants. Examples of these plants are grass, alfalfa, leaves off of trees, and bushes. As a result of the potential of rhinos becoming extinct, the plants that they eat may overgrow and leave a large amount of vegetation and grassland in their habitat.
In 2011, 448 rhino were poached for their horns in South Africa
By mid-2012, over 300 have been poached
Two species of rhino in Asia– Javan and Sumatran are endangered
Northern white rhinos are believed to be extinct
Rhinos contribute to economic growth through tourism, which helps creates job opportunities
Elephants & buffalo
Dehorning rhinos does not particularly affect abiotic things such as rocks and water, and rhinos are not affected by any certain abiotic factor
