According to Oxford Dictionary, biodiversity means the state of having a large amount of different number of animals and plants which make a balanced environment. Biodiversity is also known as flora and fauna. The meaning of flora is all the plants growing in a particular area while fauna means all the animals of an area or a period of time. Rafflessia for flora while tiger for fauna is a case in point. Crisis on the other hand means a time of great danger or difficulty, the moment when things change and either improve or get worse.
This meaning has been taken from the Oxford Dictionary. Thus, biodiversity crisis means the large number of different animals and plants are decreasing or in other word it’s facing extinction or becoming endangered. It also means that the large number of animals and plants are in a great danger. Some species that are more vulnerable to extinction than others include species at the top of food chains, such as large carnivores.
Endemic local species which is a species found in only one geographical area with a very limited distribution, species with chronically small populations, migratory species, species with exceptionally omplex life cycles and specialist species with very narrow requirements are also the examples species that are more vulnerable to extinction than others based the website, www. counrysideinfo. co. uk/biodvy. htm . The loses of an individual species may cause different effects on the remaining species in an ecosystem. The effects depend upon how important the species in an ecosystem.
Some species can be removed without any apparent effect while the removal of key stone species may have enormous affects on the remaining species. Key stone species is species that will have enormous affects on the remaining species if it is removed. To prevent the extinction of our biodiversity or endangered species, we shall conserve our biodiversity. But, what is the main reason to conserve it? There are two main reasons why we need to conserve our biodiversity. The first reason is because of ecological reasons and the second is because of the economic reasons.
Ecological is chosen as the main reason because currently ecological concern includes world- wide deforestation and global climate change. Forest are not only place for numerous different species habitat but it also plays a critical role in regulating climate. The destruction of forest most of it are because of the burning which will give results in the increase of carbon dioxide in the atmosphere. The increase of carbon dioxide in the atmosphere happens for two occasions. Firstly, because plants absorbs carbon dioxide for photosynthesis process, secondly because the burning itself cause the released during the burning process.
This is significant because carbon dioxide is one of the main greenhouse gases implicated in the current global warming trend. Global warming did cause the snow and ice cover decreased, deep ocean emperature to increase and the rise of global sea level by 100-200 mm over the last century. Rising of sea levels could drown many of our major cities, extreme weather conditions resulting is drought, flooding and hurricanes. It will also cause changes in the distribution of disease-bearing organisms. Economic reasons are chosen to be one of the main occasions of the need to conserve our biodiversity because of environmental disasters.
Examples of environmental disasters are flood, forest fires and hurricanes that might be caused by directly or indirectly by human activities. All these have dire consequences for the region afflicted. Clean-up bill can increase into billions and the toll of human misery involved. Susceptible regions are often also in the less-developed and poorer nation to be with. Erosion and desertification of land are often the result of deforestations, reduce the ability for people to grow crops and to get income to feed themselves. This will lead economic dependence on other nations.
It will also lead to the collapse of the industry involved in it. Species with great economic importance may become extinct before they are even discovered. The vast untapped resources of medicines and useful chemical contained in wild species may disappear forever. HOW TO CONSERVE BIODIVERSITY? What can we do to conserve our biodiversity? There are several ways to conserve our biodiversity. It has been divided into five groups. The first group is individual, followed by school, community, government or national level and last but not least is conservation at international level.
You must have been wandering what role can an individual do to conserve our biodiversity? We can conserve our biodiversity by discipline ourselves and stop being hedonistic and start thinking for the future if we do not conserve the biodiversity. We can recycle all the substances that can be ecycled. As a result, fewer trees will be cut down which at least can slow down the rise of temperature which is rising quickly in this time. Besides that, we can reduce the usage of air conditioners because it can also increase the temperature because air conditioners release one of the greenhouse gasses. How about schools? What role does it play?
Actually, school is the most important organization in conserving our biodiversity besides the government. A school can organize a campaign about biodiversity to enhance the student’s knowledge of biodiversity and help them to love it then conserve it. Other than that, school can also inaugurate Nature Club for the co-curriculum activities. This club shall conduct interesting activities inside and outside the school such going to the zoo and national park. A community can organize a talk about nature and ways to conserve it. This will at least make some people in the community realize about the importance of saving our biodiversity.
Besides that, a nature camp can also be done for the youths. above. Why did I say it? It’s because there’s a million of things that a government can do. A government can use the ex-situ term to conserve biodiversity. Ex-situ means ut of the natural habitat based on www. countrysideinfo. co. uk/biodvy2. htm . How can a government use the ex-situ term to conserve our biodiversity? The government can build more zoos, aquaria, and plant collection places. Zoo is a place for animals which were saved from the forest to prevent it extinct. The example of endangered species that is in a zoo is a tiger, elephant and panda.
While aquaria is for marine animal species which is near the extinction rate or usually known as endangered species. Aquaria are technically to breed the aquatic animals to prevent it from extinction and for rare species. Besides that, it is also a place to do research about marine animals and give us more information about the marine animals. Zoos and aquaria have been mentioned, but what about plant collections? What is plant collection? Plant collection is a term to describe the collection of some plant species to breed it in a specific place. This specific place is usually called botanic garden.
There are roughly 1,500 botanic gardens world-wide. Botany Garden, located at Putrajaya is one of the botanic garden in Malaysia. How can botanic garden play an important role in conserving biodiversity? As all of us know, botanic garden is a place o breed plant species which most of them are collected from the forest that is being logged down. The more plant, the more oxygen we get and the less carbon dioxide is in the air. Thus, the global temperature rising can be slowed down a little bit. Besides ex-situ term, government can also preserve the biodiversity using in-situ term of conservation. What is in-situ term of conservation?
In-situ term of conservation based on www. countrysideinfo. co. uk/diodvy3. htm is conserving between natural habitats. The in-situ term of conservation can be done in a few ways such as protecting sites or reserving, restoration and recovery of threatened pecies. Protecting sites or reserving means that a forest has been protected from illegal loggers or in other word it can’t be logged down. Trespassers into the forest can be prosecuted by the laws. Reserving a forest can make so much benefit for the biodiversity such as the habitat of animals in the forest is held in reserve and can’t be destroyed.
Thus, the next generation can see the same species of animals we can see today. Restoration means attempt to bring land modified by human use back to its original state. Restoration is done because determining the original natural state s often difficult and because ecosystems continually change, this is rarely a realistic goal. Changes in some cases are irreversible, so that the reforestation to an original is not an option. The benefit of restoration is some species of endangered plants can be saved from extinction, thus, the number of extinction of plants can be decreased.
Recovery of threatened species usually hinges on providing suitable habitat and conditions in which they can survive. The example of this is a panda must be kept in a condition which have suitable temperature that they can survive and there must be a bamboo trees or leaves. This is because if neither of this is present in a place to protect a panda, such as in a zoo with no bamboo trees or leaves and non-suitable temperature, the panda will eventually dies. Consequently, the natural condition for the life of the species is needed to protect it from extinction. Besides government or important role.
This is because some of the animal species mostly birds and fish, migrate from one place to another or in other word, they migrate from one country to another. Thus, international conservation plays an important role in the wide publicizing of environmental information. There are also some international rganizations that conserve the biodiversity around the world.
