Protecting Ecosystem

Protecting Ecosystems : - Although Australians now take it for granted that humans need to protect natural ecosystems, the idea is relatively new in Western civilizations. For this reason, the science of ecology has only been taken seriously over the last 50 years. Four reasons for protecting ecosystems are :

  • Cultural value : - Some species have a value as part of the way of life of a country or region. For example, a kangaroo, emu and golden wattle are included in the Australian cost of arms shown in  These organisms are part of our national view of ourselves and Australians would not allow these animals to be hunted to extinction or the plant killed off. Likewise, New Zealanders would be furious if the kiwi of the silver fern became extinct
  • Economics : - Some plants and animals have an economic or financial value. People can make money from ecosystems in many ways. For example, many tourists want to see untouched ecosystems and so these ecosystem provide income and jobs. Harvesting from the wild or farming species such as eucalyptus trees, prawns or kangaroo also creates wealth. New pharmaceutical drugs are still being discovered using plants that had not been previously tested. Some animals could be possible biological control agents for controlling new pests.
  • Compassion in humans feeling sympathy for other organisms  : - The idea of compassion is that all organisms have a right to live, and that humans are the only organism on Earth capable of understanding the possible fate of all life, then surely we have a responsibility to make wise decisions.
