Importance of Conservation Essay The term wildlife has been used to refer to species of wild plants and animals. Nature is a term which infers not only life forms but also the interactions between those life forms. Biodiversity is a comprehensive word for the degree of nature’s variety, including both the number and frequency of ecosystems, species and genes in a given assemblage. It is a word which embraces both species richness and genetic diversity, both of which are being threatened throughout the world. Species extinctions and a reduction in genetic variability is taking place at rate never before witnesses. These losses can be attributed to various factors including pollution, physical disturbance, exploitation for food and other uses, deliberate extirpation, and habitat loss and fragmentation; the last of these is undoubtedly the most serious threat. Symptomatic of the rapidly growing human population, pollution, extinctions and habitat loss are all contributing to a diminished quality of life for future generations (Spellerberg, 1992). Conservation of Botanical Diversity Plants are the basis for life on Earth and without their capacity to capture the sun’s energy through the process of photosynthesis there would be no life in our planet. Therefore the conservation of plants is vital to the continued existence of life. There are between 250 and 300 thousand species of flowering plants, an estimated 200 thousand species of ferns, conifers, mosses and liverworts, giving a total of over half a million plant species in the world. Each species has different habitat requirements, performs different ecological functions in different ecosystems and has different uses or potential uses for humankind. It is not then enough to preserve a few selected plant species. For the survival of a quality of life, and the maintenance of the physical processes such as climate patterns, atmosphere and soil, the majority of plant species are needed. It is, therefore, of utmost importance that conservation techniques for plants aim at preserving as many species as possible (Maxted, Ford-Lloyd, Hawkes, 1997). Nature Conservation and Landscape Ecology Nature conservation generally focuses on land and distinguishes between two main types of protected area: the national or international parks, and reserves. Like in the case of Konza Prairie Trail, aside from research purposes, the site is also being conserved to preserve the biodiversity in the area and save the animals that are living in the site (Mason, 2007). National/international parks are heterogeneous areas in which generally different biotopes are present and in which some processes are sufficiently conserved. Reserves are generally patchy and smaller, being surrounded by an agricultural or developed matrix. Nature conservation plans are generally achieved following three main approaches: Conservation of threatened plants and animal populations; Conservation of representative biotopes (a piece of land with a particular type of nature), including communities and ecological processes; Conservation of areas with high biological and/or ecological diversity Generally conservation policies tend to conserve structures rather than processes. Landscape ecology can be useful for nature conservation because it takes into consideration the spatial arrangement of habitats, and consequently considers structures and processes as perceived by the different species. This perception often does not coincide with human perception, creating difficulties when management action is required. A compromise should be found, since in the future wild, remote and large areas will be increasingly rare because of human intrusion (Farina, 1997).

The Diary of Anne Frank :: essays research papers

The Diary of Mrs. Frank D-day 1944,   Ã‚  Ã‚  Ã‚  Ã‚  I feel terrible. I don ‘t know what I was thinking, trying to kick Mr. and Mrs. Van Daan out of our hiding place. My family has never seen me like this. I must’ve forgotten to tell you what happened. Well, let me tell you. We were all sleeping when I opened my eyes, and saw Mr. Van Daan stealing bread. I immediately woke up everyone, by screaming and shouting at him. My husband had to hold me away from Mr. Van Daan, or else I would’ve hit him with my fist. I was so ashamed of myself, thinking how my family must’ve felt about me,. Anne already hates me. Think of how embarrassed she must be, to have a mother like me. Afterward, I told them to leave at once. My dear husband, thankfully, tried to pacify me that I was only speaking in anger, but I just could not listen to him. Soon, Peter came storming in the room yelling D-day has occurred, while I was just sitting there ruining everyone’s celebration by crying. I was mad at myself fo r not being very polite to our hosts, after all they have done for us. This is a very happy moment for all of us that D-day has landed. Maybe, just maybe, liberation will occur.   Ã‚  Ã‚  Ã‚  Ã‚   Hanukkah, 1942,   Ã‚  Ã‚  Ã‚  Ã‚  It is I again, here to report the daily news. Today was the Jewish holiday, Hanukkah. Every year we give presents to our family and friends, but this year we can scarcely go to the bottom storey of our shelter to get presents. We all felt disappointed about not getting or receiving gifts, but I felt the worst. You see, Anne had managed to brighten up Hanukkah with presents for all.

Chinese Food Essay

China is a country which has a long history and tradition dealing with food, especially eating habit. There are lots of rules or customs about how to eat in a polite way. First of all, the way you eat can sort of show your social. The funniest habit is that Chinese people share food; this means that all the dishes are placed on the table and everybody can eat whatever they want. Moreover, Chinese dining customs are built on tradition; they are not casual. People should talk less while eating when it is an official situation or the atmosphere is really serious because when you have food in your mouth and you want to talk, there is high possibility that the food is splashed from your mouth, then it would be really rude and impolite to others. In addition, Chinese people never place those chopsticks vertically in rice even they are eating at home because Chinese people incense dead person by inserting two sticks of incenses upright into sand or rice. Therefore, it looks like people who place those chopsticks like that are wishing death upon other people at the table. What people should do is place those chopsticks on the dish or rest them on the chopstick stand. At the same time, any kinds of sounds are not allowed either. People should eat quietly and slowly in order to show politeness and respect, this means people shouldn’t tap on the bowl with chopsticks or spoons. Following these eating habits can help people feel comfortable and relaxed when they are eating with others.

Do Fish Feel Pain The Science Is In

The reasons for not eating fish range from animal rights concerns to the effects of overfishing on the environment. Do Fish Feel Pain? Its easy to dismiss the lowly fish. They are so low on the food chain they’re easily forgotten in animal rights conversations. Thoughts about the feelings of fish are not nearly as sexy as some of the bigger campaigns such as greyhound racing, dolphin slaughter and horse soring. In a 2016 focus essay written by Brian Key, Head of the Brain Growth and Regeneration Lab at the University of Queensland and published in a peer review journal entitled Animal Sentience, Key makes the point that fish do not feel pain since they lack certain brain and neurological functions necessary to act as pain receptors. After mapping the brains of fish, Key concluded â€Å"that fish lack the necessary neurocytoarchitecture, microcircuitry, and structural connectivity for the neural processing required for feeling pain.† But some of his peers strongly disagree, and more scientists and biologists are conducting their own studies which, frankly, directly contradict Key’s assertions. For example, Yew-Kwang Ng Division of Economics Nanyang Technological University in Singapore, argues that Key’s opinions are not salient and do not â€Å"support a definite negative conclusion that fish do not feel pain†¦ many researchers believe that the telencephalon and pallium in fish may be performing functions equivalent to some functions of our cerebral cortex.† In other words, fish most definitely have the ability to feel pain. Ng has written over a hundred essays on what he calls â€Å"welfare biology,† or the study of reducing suffering in wildlife. He appears to be passionate about his work, and wouldn’t be pushing the idea of welfare biology if he didn’t believe that animals were truly suffering. The movement can use more scientists who are engaged; and the world can use more compassionate scientists who offer statistics, proof and raw data about animals. These studies strengthen not only the argument for animal rights, but also our resolve to keep raising the bar until all animals are safe from exploitation, pain and death. Even fish. It turns out they can count too. According to a 2008 article in The Guardian, fishies got some math skills! The subject of fishing has long been the red-haired step child in the animal rights movement. With so many other atrocities being addressed by the movement at large, it’s sometimes easy to forget that fish are indeed animals and should be included in discussions about animal rights. As Ingrid Newkirk, co-found of PeTA once said, â€Å"Fishing is not a harmless activity, it’s hunting in the water.† In a December, 2015 article for the Huntington Post, Marc Beckoff, Professor emeritus of Ecology and Evolutionary Biology, University of Colorado tells us that not has science proved fish feel pain, but it’s time we all â€Å"get over it and do something to help these sentient beings.† Touchà © Some may question whether a fish is capable of feeling pain. I would ask those questioners if they have their own motives for denying a fish’s capacity for pain. Are they trophy hunters? Parents looking to bond with their kids? People who like to fight with big gamefish because they â€Å"put up a great fight†? Are they consumers of the fish they catch and eat? I once chastised a kid for terrorizing a family of ducks living peacefully on a pond in a park. The kid was heartlessly chasing the ducks, while the mom looked on dispassionately. I asked the mom, â€Å"Don’t you think it’s wrong to teach your kid that it’s ok to torment animals?† She gave me a blank look and said â€Å"Oh it’s harmless, he’s giving them some exercise!† Seeing the look on my face, she asked â€Å"You fish don’t you? What’s the difference?† I don’t fish, of course, but her assumption that I did spoke volumes. The general public thinks of fishing as just a pastime, or sport. Many self-titled â€Å"animal lovers† not only eat fish, but catch them as well. They’re quite annoyed when I point out that, though they believe themselves to be compassionate, their empathy may extend past their own dogs or cats to the factory farm, but stops at water’s edge. Watching a terrified fish struggle at the end of a fish hook is enough evidence for most people who believe all animals are sentient, but it’s always good to have the science to back it up. Numerous recent studies have shown that they do feel pain. [Note: This is not an endorsement of animal experimentation, but the  ethical objections to vivisection  do not mean that the experiments are scientifically invalid.] For example, a study by  the Roslin Institute and the University of Edinburgh  revealed that fish reacted to exposure to noxious substances in ways that are comparable to â€Å"higher mammals.† The reactions of the fish to these substances, â€Å"do not appear to be reflex responses.† A study conducted at Purdue University showed that fish not only feel pain but will  remember the experience and react with fear afterwards. In the Purdue study, one group of fish was injected with morphine while the other was injected with a saline solution. Both groups were then subjected to uncomfortably warm water. The group injected with morphine, a painkiller, acted normally after the water temperature returned to normal, while the other group â€Å"acted with defensive behaviors, indicating wariness, or fear and anxiety.† The Purdue study demonstrates that not only do fish experience pain, but their nervous system is similar enough to ours that the same painkiller works in both fish and humans. Other studies show that  crabs and shrimp also feel pain. Overfishing Another objection to eating fish is partially environmental and partially selfish: overfishing. While the array of fish available in the supermarket may lull some into believing that overfishing is not a serious problem, commercial fisheries around the world have been collapsing. In a 2006 study published by an international team of 14 scientists, data indicates that the world’s supply of  seafood will run out by 2048. The Food and Agriculture Organization of the  United Nations estimates  that â€Å"over 70% of the world’s fish species are either fully exploited or depleted.† Also, In the last decade, in the north Atlantic region, commercial fish populations of cod, hake, haddock and flounder have fallen by as much as 95%, prompting calls for urgent measures. The drastic reduction in certain species could have dire consequences for entire ecosystems. In the Chesapeake Bay, the mass removal of oysters appears to have caused  significant changes in the Bay: As the oysters declined, the water became cloudier, and sea grass beds, which are dependent on light, died off and were replaced by phytoplankton that does not support the same range of species. However,  fish farming is not the answer, either from an animal rights standpoint or an environmental one. Fish raised on a farm are no less deserving of rights than those living wild in the ocean. Also, fish farming causes many of the same environmental problems as factory farms on land. Whether the concern is about the decimation of a food supply for future generations, or about the domino effects on the entire marine ecosystem, overfishing is another reason not to eat fish.
