Ecosystems and their species perform important biological services, for example, green plants remove carbon dioxide and release oxygen into the air, which helps keep the environment healthy and fit for life. people. Although we still have much to learn about the often complex functions of ecosystems, and about which species play critical roles, we do know that if an ecosystem is altered in any way, it may not be able to perform some of its essential services.
Economic arguments also provide compelling reasons for species conservation. The various species of plants, animals, fungi and micro-organisms provide us with food, medicine, fuel, building materials, fiber for clothing and industrial products.
Biological Services Performed by Ecosystems :
Protecting areas from landslides, floods and other dangerous weather conditions: Vegetable cover helps to protect soils from landslides. Woodlands and hedges provide useful windbreaks in farm areas, and plants in mudflat and sand dunes can help protect coastal areas from sea and wind erosion.
Reducing the risk of local and global climate change: Ecosystems help maintain a healthy balance of atmospheric gases. Trees and other plants store carbon and help prevent the formation of carbon dioxide in the air, reducing the risk of global warming.
Recycling of nutrients: Bacteria and fungi play an important role in recycling nutrients in ecosystems. Some plants play an important role in regulating nitrogen in the soil. Nitrogen fixation is the process of converting atmospheric nitrogen to ammonia.
Controlling pollination and biology: Some animals, especially birds, bats and insects play important roles as pollinators of food plants such as vegetables and fruits, and are often natural enemies of weeds, pests. and diseases that can damage crops.
Controlling pollutants: Plants like reeds act as natural filters, helping to remove waste from surface water and many bacteria can help break down low levels of pollutants.
Environmental health monitoring: Some species may indicate environmental change. For example, breeding failure in prey birds may point to a development of pesticides in the system. Lichens such as those found growing on your school walls and on trees can be sensitive indicators of air pollution levels.
Economic Value
Food: The provision of food is the most basic benefit that people derive from other forms of life, and people are always dependent on animals and plants for meat, fruits, vegetables, nuts, etc. natural products.
Medicines: The wild species has been used as a source of medicines for thousands of years. The medicinal potential of plants and animals is often considered a compelling reason to preserve biodiversity because some species are highly valued for their medicinal properties.
Commercial goods: Human societies traditionally use plant and animal products such as wool and fur for clothing, and wood for building and fuel construction. Other plant and animal products used in the industry include feathers, leather, glue, rubber, oil, waxes, starches and dyes.
Cultural and Aesthetic Values: Historically, some species have played an important role in the legends and traditions of many cultures. Species can also have heritage value as national symbols: for example, in Ireland, the three-leaf clover (Trifolium) symbolizes the identity and heritage of the country. Biodiversity also has an important appreciation and appreciation for appreciation. Biodiversity also has educational value and inspiration.
Intrinsic Values: For example, knowing that something exists is satisfying in itself, and the loss of a charismatic species, such as giant pandas and blue whales, represents a substantial loss of 'value of existence' . However, it is impossible to count and, unfortunately, many species, such as slugs and slime molds, will never enjoy the ‘value of existence’. Many people also hold strong personal beliefs, feel a great respect for the whole of nature and a responsibility to be given to the next generation of a world as rich in life as the world we live in today.
"I can not imagine what is more important than air, water, land, energy and biodiversity. These are the things that keep us alive." "People still do not understand that a live fish is more important. than a dead one, and destructive fishing techniques take a damaged ball to biodiversity. "
