Source: https://www.allbioconcerns.com/2018/09/importance-and-practices-of-conservation.html Human needs are limitless. We don't give back to the earth an equal amount of what we take from it. Is this a problem? If then, how can this problem be solved? Are there vital lessons we need to learn to boost our practices of conservation for natural resources? Read this article Natural resources Natural resources are substances not created by man but are needed by man for economic gain and development. They include Crude oil, coal, wide life, water, air, minerals etc. Classification of natural resources Natural resources can be classified by different methods. Classification based on origin Biotic resources: Obtained from living and/or organic substances like trees, animals and their products, coal, etc. Abiotic resources: These are obtained from non-living, non-organic substances like gold, iron, water, etc. Classification as renewable and non-renewable Renewable resources: These are resources that their rate of replenishment is greater than their rate of usage. Examples are sunlight, air, water, etc Non-renewable resources: These are resources that have a slower rate of replenishment/formation with regards to the rate of usage. Examples are fossil fuels There are more methods of classification but these are enough for now. The main point is non-renewable. The term 'non-renewable' may be used to refer to a number of resources today and a greater number tomorrow. For instance if elephants' gestation period (period of pregnancy) is about 22 months and they're killed 1/day for their tusks, it wouldn't take long before their population will reduce to zero. Well, the actual figure as at 2017 is 1 for every 25 minutes. If only the killings would reduce, the status of wide life may be taken back to a renewable resource. Other examples of natural resources that need our urgent attention are forests, oil, atmosphere, etc. Introduction to conservation In a plain definition, conservation means maintaining, protecting and retaining anything so it would last longer. The biological term 'conservation' is an ethical term used to refer to management of the earths natural resources in order to protect nature's biodiversity and ecosystem stability. For instance, if we over use bamboo trees and their growth rate can't keep up with our consumption rate, our actions are directly affecting the tree and indirectly affecting organisms like Pandas that depend on the tree for survival. Pandas which were classified under endangered species are now recovering because of the conservation of the species and their habitat. https://images.chinahighlights.com/allpicture/2014/08/83ca639142da4c628a5cab6c_299x198.jpg A Panda's primary diet is the Bamboo tree Importance of conservation Practices of conservation have countless numbers of importance. Their importance can never be over-emphasized. Stability of ecosystems Every organisms and substances have roles to play wherever they're found. For example, if we overuse the trees in the earth for buildings, making papers and other reasons, the oxygen in our air will become scarce, herbivorous animals (animals that depend on plants for food) would get lesser amount of food therefore leading to competition and reduction of their population, carnivorous animals (animals which feed on other animals) wouldn't get enough food to eat, humans in turn would not get enough food to it (no vegetable, no fruit, no meat and no animal product) and our population would reduce drastically because of starvation and lack of oxygen. See the impact of not conserving our trees. Would we want this to happen? Availability of natural resources to future generations There's no doubt that if we don't conserve our resources, today, our children may only see these resources in museums, zoos, schools, etc. The resources may not be available in commercial quantity. If crude oil takes between hundreds of thousands to millions of years to form and we use an average of around 90 million barrels daily, how long would we wait for a refill? Continuity of our development If natural resources are needed by humans for creation of materials used to make buildings, roads, appliances and other important sources of our civilization, it means that an aspect of our civilization and development would cease the moment a specific resource becomes too low in quantity. Continuity of the earth's biodiversity It's no longer news that the lovely bird 'Hyacinth (or blue) macaw' that inspired the movie 'Rio' is now extinct in the wild. More organisms (plants and animals) are on their way to extinction if nothing is done. Do we really want this to happen? https://upload.wikimedia.org/wikipedia/commons/thumb/c/ce/Anodorhynchus_hyacinthinus_-Disney_-Florida-8.jpg/220px-Anodorhynchus_hyacinthinus_-Disney_-Florida-8.jpg The Blue macaw now extinct Solution to pollution Pollution is the presence of wastes in the environment. Wastes are materials that are not needed. Even though some wastes can be recycled, not all are recycled. If only we can reduce our use of natural resources, we would have less wastes therefore possibly recycle all our recyclable wastes. If petroleum used to make plastics gets exhausted, we'll have no choice than to recycle our plastic wastes. Why not recycle more wastes now so we conserve petroleum? As you can see, conservation has a to large role to play for the sake of our tomorrow. Let's move on to how we can conserve Practices of Conservation Conservation is not general meaning the application varies from a resource to another though all practices' mission is availability of the resource for future use. For we to conserve, we need to: *Know the amount of the specific resource left *Know our use for it *Check is it's renewable or non-renewable *Look for alternative renewable sources that would give us similar or the same product like the resource we're conserving *If the products of a particular resource is recyclable, let us recycle them instead of discarding them as wastes *Create awareness so others would get involved with the practices of conservation. Read Environmental awareness/Plastic pollution campaign published here on nairaland *Let us now look at some natural resources that need conservation Forest The forest is very important. It provides wood for construction, plants for consumption of some animals and canopy for various organisms. Wiping out the forest would have very bad impacts on the Earth, Well, how would we conserve our forests? Using the list above, we need to know how much forest is left. Forests which are supposed to cover 31% of the earth's land surface which is around 4 billion hectares (was around 6 billion during the pre-industrial era) are reducing by about 7 million hectares yearly. Forests really need our help. Our industries' major uses of forests are construction of buildings and making of paper. Rural places cut down trees to get fuel for heat and fire. We can conserve our forests by replacing wood as a source of fuel with alternative sources like heater, stoves, coal or even solar panels. Schools can use more phones and tablets instead of books, construction companies should re-use woods used as temporal materials in buildings and there should be laws governing these companies to be conscious of the amount of trees they cut down and we should also plant and monitor the growth of trees. Wildlife Wildlife retains the biodiversity of nature. We feel wonderful when we see wild animals in zoos and other places. To some people, they've got other uses to these wild animals. For example: *Elephants are killed because of the value of their tusks *Helmeted hornbills are killed because of the value of their beaks *Tigers are killed for protection from their attacks and illegal wildlife trade *The population of most species is reducing because of loss of habitat. For example Koalas eat only eucalyptus leaves (gum leaves). Reducing the population of the eucalyptus trees is reducing the population of koalas [img]https://4.bp..com/-6Ybky7Bg5yA/W7Gu04UdiDI/AAAAAAAAEXw/g9gXB2ZIuyAMPmR45IFhN-jkslj0pyF7wCK4BGAYYCw/s320/Endangered%2BHelmeted%2Bhornbill.png[/img] The beautiful helmeted hornbill on the brink of extinction We should know animals on the brink of extinction and stop the killings and any other of our actions that have negative impacts on their population. We should encourage our leaders to support our practices of conservation of wildlife, we should open game reserves and other conservation units to protect the animals and should check the population constantly for increase or decrease to know the results of our actions Oil and natural gas These are non-renewable natural resources. We have countless uses for them. We use them for production of fuel, plastics, etc. As earlier stated, oil takes so many years to be formed. If we continue using these resources without conservation, they won't take up to 50 years to completely run off. Overusing these resources is one of the reasons why our atmosphere is polluted with poisonous gases and our lands and seas are filled with plastics. Some of our conservation practices for oil and natural gas includes: *Finding alternative sources of power like biofuel, solar panels, etc *Buying vehicles that don't require products of oil and gas therefore reducing the demand *Reduce, reuse and recycle plastics. Read Everything to know about plastics *Government should provide capitals to people who have ideas about making cars, generators, etc that don't rely on oil Natural resources in the earth are like money in our bank accounts. The more we withdraw, the emptier the account becomes. Even if we deposit money into our bank account, the account will get empty if we deposit lower than we withdraw. Let's remain hopeful that our conservation practices would have great impacts on the resource we're conserving and thus help nature so that the coming generations would view nature as it is.

On the 29th of June 2018, students of Animal and Environmental Biology U2016 set went outside their school University of Port Harcourt to campaign against Plastic pollution and other environmental issues. Our mission Our mission is to enlighten everyone we meet in the street about the various problems we find in our environment like littered roads, flooding and others especially plastic pollution. We also want to use the opportunity to invite people to study in our department 'Animal and Environmental Biology'. To fulfill our missions, we printed two different types of flyers. One for Environmental/plastic pollution campaign, the other for our department Our preparation We've always planned to do this rally either on World Environment day (5th June 2018) or on our community service day which was the 16th of June 2018. We postponed this movement to the 29th of June 2018 due to some factors like preparedness. We had to notify our department staffs about our campaign so they'll support us, notify the school security so they'll permit us to do a rally both within/around school and notify the Commissioner of Environment for Rivers state (who is also a staff in our department). After all consultations, we finally agreed to do the campaign on Friday the 29th of June 2018 Our movement The day finally arrived. We've chosen white and blue as the color of the day. Our shirts were white, trousers/skirts were blue. Everyone cooperated with this arrangement. We chose Choba, a community not far from our school for the rally. We had to assemble in our department, trek to Choba junction and campaign in different streets in the community. We all assembled by 1pm and our movement started by 2pm. By then, our banners, bus and musical instruments, entertainment, badges and flyers were ready.

We also campaigned with two waste bins. We used them to pick up whatever plastic we find on the road and also keep our dirt in it so we won't litter the environment we're trying to save.

We hope that more campaigns will be done to enlighten people elsewhere so they value and care for the Earth. Lastly, we hope that we can have more applicants of Biology-related disciplines like the department of Animal and Environmental Biology.

In recent years, we humans have been learning from nature. Scientists and engineers don't just learn but also apply what they learn. What are a few out of thousands of lessons we've gotten so far from nature? What are proofs that engineers have learnt from nature to build/modify items and structures? Read this article How the scorpion inspired NASA The National Aeronautics and Space Administration got inspired from the legs and movement of a scorpion to develop a multilegged robot. A scorpion walks freely on rocky and rough terrains. Most often, sites that NASA is interested to study are on rough terrains or even on the sides of a cliff. A car or any machine which has big wheels can pass through a rocky terrain but can't pass through small spots. If smaller wheels are used, the machine can get stuck in sand. The best solution is to design a machine with legs so that all legs will support each other. That's where the scorpion came in handy [img]https://3.bp..com/-8yVWissn0lA/WygkUBm4_bI/AAAAAAAAESo/95nt06QWJs8OQOGCYlaQR9HMcZjQB8c3gCK4BGAYYCw/s320/Engineers%2Bhave%2Blearnt%2Bfrom%2Bnature%2Bhow%2Bto%2Bproduce%2Bsuch%2Bscorpion-like%2Brobot.jpg[/img] Imagine a fabric material that adjusts to suit its wearer's temperature Imagine if one part of your body is hot and sweaty then the dress you're wearing opens up a bit (just at the sweaty part) to cool down your body temperature. Won't it be cool? Well stop imagining because such fabric is real and its production was inspired by the opening and closing of the pine cone's flaps. The reason behind the opening and closing of the pine cone's flaps is change in humidity. When warm and dry, the flaps open up to release seeds. When damp or cold, the flaps close up. Now, this material was designed using the reverse mechanism so that when it's wet in the inside (because of sweat), it'll open up and close as the sweat reduces. Each flaps in the material is just 1/200 of a millimetre. The material also features a water proof layer so that rain from thee outside won't pass through. This cool fabric was inspired by nature. Ultra-thin, high-speed motion detecting lenses You may know that insects have compound eyes (i.e eyes filled with lenses that view different directions) but you may not know that an insect like a dragon like could have around 30,000 lenses in just one eye. That's about 60,000 lenses in both eyes. Each of these lenses combine to produce images like a wide mosaic view. Because of such compound eyes, the dragon fly are superb at detecting movements. Now, engineers have developed an artificial compound eye that fits 8,500 lenses into a space the size of a pinhead. This compound eye however, would be attached to image sensors like cameras. This will modify high speed motion detecting sensors. https://assetsnffrgf-a.akamaihd.net/assets/m/1102010232/univ/art/1102010232_univ_cnt_12_xl.jpg Autopilot systems and navigation of our aircrafts inspired from the Monarch butterfly Monarch butterflies are able to migrate from Canada to Mexico yearly without losing their way. These butterflies have a brain with the size of the tip of a pen. How do they navigate with such a tiny brain? They do this with the aid of the sun. Since the sun rises in the east and sets in the west, they know that the sun travels from east to west. Traveling from Canada to Mexico is more like travelling from the north east to the south west so these butterflies rely on the sun for their Migration. Planes using a device the size of a debit card also mimics the butterflies. This device not only guides the plane from country to country, but also aids to land the plane. Engineers have learnt from nature how to produce such devices https://www.telegraph.co.uk/content/dam/news/2016/04/15/1028461_Monarch-butterfly-NEWS._AP_P_trans_NvBQzQNjv4BqjetDlLkkivkos2TN100DmFkiei7Fym8CYupLAL_REXo.jpg?imwidth=1240 Mimicking the wings of a seagull Well, it's already certain that the wings of aircrafts were inspired by the wings of birds. This time around, engineers have taken this mimicry to new heights. How? When seagulls are maneuvering in the air, they flex their wings at the elbow and shoulder joints. This allows them to maneuver freely in the air. Engineers have made drones with movable wings so that they can easy dive between tall buildings by just maneuvering. [img]https://wol.jw.org/en/wol/mp/r1/lp-e/lc/2010/49[/img] Learning from the beak of a squid You may know that squids have no bones. You may also know that their skins are all soft and appear like jelly. What you don't know is that their beaks are among the hardest materials on Earth. The beaks are so hard that they can slice through fishes like a very sharp knife. How does such a hard material fit into a soft material? Observing the beak of the squid, scientists discovered that the tip is hard while the base is soft. The beak is made up of chitin, water, and protein which changes in density from position to position so gradually from soft to hard. This knowledge can be applied into various aspects. Engineers can use this knowledge to attach different materials together. One application is the making of prosthetic limbs that would match the elasticity of cartilage on one side and be stiff in the other side. This is one of what engineers have learnt from nature. https://i1.wp.com/craphound.com/images/squid_beak.jpg?w=970 Now that we know a few of what scientists and engineers have learnt from nature Let us give the natural world and Biology their credits. Biology isn't just the study of life but also the application to the modification of our lives. Let us always study nature.
