All three were chosen on World Environment Day on 5 June 1990 by President Soeharto. On the other occasion "Bunga Bangkai" ("Titan arum") was also added as "puspa langka" together with Rafflesia. Each of Indonesian provinces also have their own floral emblems. To build respect and love for the Indonesian flora and fauna, the Government has declared 5 November as the national love flora and fauna day. Annually there are postage stamps released with this motto. They show pictures of plants and animals, which are endemic or unique to a specific region or a province of Indonesia. Deforestation is a major problem in Indonesia. The current rate is a loss of 2 million hectares per year. As a highly populous country with the tendency of rapid industrialisation, the need of natural resources and land also increases. Illegally created wildfire causes heavy smog around Indonesia's neighbour countries. According to the Indonesian department of forestry, there are currently 174 plants endemic to Indonesia listed as endangered species. Maintaining the balance between the need of economical growth of the country and the preservation of its natural heritage is not an easy duty. Just like other developing nations, Indonesia is currently trying to keep this balance. Ecotourism might be one solution to this problem. Using the biodiversity, Indonesia might improve the economical status of its isolated regions.
