They are believed to have died from shocks sustained by hitting an electric fence surrounding a plantation. Many residents in the region have installed electrical fences around their land or homes to protect their property and crops against animal attacks. /VCG Photo

The Sumatran elephants are a critically endangered species. Their population is falling because of poaching for ivory, or are killed for damaging crops. Also, the elephants’ habitat has been devastated by industrial activities such as logging. Currently, there are about 1,700 Sumatran elephants left in the wild. /VCG Photo
