Answer:
Topic: Komodo Dragons.
Cause - invention on invention (when, why, who,etc): “The Komodo dragon was first documented in 1910 by Lieutenant van Steyn van Hensbroek who went to Komodo Island after hearing stories about giant lizards. He killed a dragon and sent the skin and several photographs to Peter A. Ouwens, director of the Zoological Museum and Botanical Garden at Bogor, Java, who eventually determined that the dragon was a monitor lizard. Several expeditions followed including an expedition led by W. Douglas Burden which captured 27 specimens and examined at least 70 individuals in 1926.
Positive Effect 1 + Support Details: Although dangerous, the Komodo dragon is considered to have a positive impact in increasing the income of the community within Komodo Village (100%) through tourism sector, while only 23% of the Rinca people felt the positive impact of the Komodo dragon's presence.
Positive Effect 2 + The residents of Komodo Village were dominated by natives (90%) with a very small population of immigrants, while those of Rinca Village, were dominated by migrants from Flores-Bajo. The majority of Rinca villagers are currently engaging in fisheries as fisherman and dry fish traders, in contrast to Komodo villagers who are mostly engaged in the tourism sector. The perceptions of the Komodo Village community towards their interactions with Komodo were categorised as good (60.6), while the perceptions of the Rinca Village Community were in the moderate category (47.6).
Negative Effort 1 + Support Details: The team found that the dragon's venom rapidly decreases blood pressure, expedites blood loss, and sends a victim into shock, rendering it too weak to fight. In the venom, some compounds that reduce blood pressure are as potent as those found in the world's most venomous snake, western Australia's inland Taipan.
Negative Effects 2 + Komodo dragons have shark-like teeth and poisonous venom that can kill a person within hours of a bite. Yet villagers who have lived for generations alongside the world's largest lizard were not afraid — until the dragons started to attack.
