Nature conservation is important for the protection of biodiversity. Biodiversity is the variability among living organisms from all sources, including terrestrial, marine and other aquatic ecosystem and the ecological complexes where they are part of. It includes the diversity within species, between species and ecosystems. Therefore, biodiversity is a fundamental of life support system and it forms the foundation of ecosystem service to which human actions is intimately linked. Biodiversity is consisted of many elements including living things for example animals and plants, non-living things (soil, sunlight, water, air) ecosystem and the interactions between living things and non-living things. Therefore, none of the organism can live in …show more content…
Rainforests play an important role in maintaining the balancing of the global ecosystem and environment. Rainforests help to regulate the surrounding temperature. This is because rainforest is also known as the ‘lungs’ of the earth as rainforest absorbs huge amount of carbon dioxide and release huge amount of oxygen. Carbon dioxide is heat trapped gas. Therefore, when the plants in rainforest used up carbon dioxide in photosynthesis, it helps to reduce the composition of carbon dioxide in air and thus reduce the surrounding temperature. Therefore, destruction of rainforest may cause the production of greenhouse gases which causes the surrounding temperature to rise. This results in the melting of the ice cap in Arctic and Antarctic which causes the rising of sea level. As a results, floods may occur in the low land all over the world. Rainforest also acts as a water reservoir in global ecosystem. This is because one of the criteria to be recognized as rainforest, an area much receive at least 80inches of rain every year. Therefore, rainforests help to maintain the water cycle by producing large amount of rain every year. Water produced by rainforest makes its way all over the world. Hence, the destruction of rainforest may affect the water cycle system which lead to droughts in different area all over the world. Rainforests also act as the habitats for half of the plants and animals found in the world. Thus, destruction of rainforest may cause the loss of habitats for the flora and fauna. Thus, nature conservation helps to maintain and reserve the natural resources that can be found in
Nowadays, earth has been facing a series of severe environmental issues which require urgent attention to make the ecology friendly, and global warming is considered as the most vital one. Although some people doubt and disagree that global warming is happening, climate change is real and it is mainly influenced by human activities through the increased production of green house gases such as methane and carbon dioxide. Global warming has the effect of melting polar ice caps and glaciers, which will lead to sea level to go up. Moreover, due to the rise of sea level, the survival of those people who live in islands and coastal cities can ultimately be threatened. Deforestation has been considered to be one of the most important contributing factors to global climate change. Also, since trees absorb greenhouse gases, reduce carbon emissions, and produce oxygen, without trees, the greenhouse effect can be improved tremendously. As World Resources Institute has pointed out in the data, forest loss contributes between 12 percent and 17 percent of annual global greenhouse gas emissions. Thus, what is “deforestation”? Why do people have to deforest? How does it affect environment?
are at a very high risk of extinction. There are over 3000 endangered species around the world due to many factors including over-fishing, hunting, destruction of habitat, climate change and a decrease in food supply. As the number of endangered species are increasing quickly it is very important that action is taken to preserve them for a number of reasons. If endangered species are not preserved it could easily lead to the species becoming extinct which could upset the food chain and lead to further extinction of other species. This could have not only negative effects on there predators but would eventually lead to having negative effects on species further up the food chain including the human species. Over the years researches have come to discover and find that all species play an important part in looking after our ecosystem and extinction could cause a big hole in the system.
Hello United Nations! I am going to start off by telling you a little bit about us and our organization. We are the Organization for African Endangered Animals. We are a private agency in Africa who protect the welfare of endangered animals. We are the voice of the animals. They cannot speak for themselves so we speak for them. We do our best to protect our animals but we have limited sources and funding. Our focus right now is one of the most endangered species in the world, the Dama Gazelle.
First of all I would have to say that yes it has a great impact on our global warming and I will go on to explain to you how it affects our planet. We as a whole have let the dollar get in the way of how our planet is affected, some would say at all costs. It is true we have refineries, car pollution, but most of all deforestation of tropical areas. In the National Geographic Magazine you will come to see and appreciate the facts of how deforestation has affected our nation and has spiraled into global warming. We can look at Brazil’s rainforest that is estimated to be larger than two hundred football fields it will be destroyed before you are even able to read the article at hand (Magazine, 1996-2014). It has been noted that within the past 40 years we have managed to do more damage than what was done in the four hundred and fifty (450) years since the European Colonization even began. That sent chills through my bones when I read that, imagine how much tropical areas have been affected. We have destroyed twen...
Environmental issues affect every life on this planet from the smallest parasite to the human race. There are many resources that humans and animal needs to survive; some of the most obvious resources come from the forests. Forests make up a large percentage of the globe. The forests have global implications not just on life but on the quality of it. Trees improve the quality of the air that species breath, determine rainfall and replenish the atmosphere. The wood from the forests are used everyday form many useful resources. Moreover, thinning the forests increases the amount of available light, nutrients and water for the remaining trees. Deforestation (forest thinning) is one of the most critical issues of environmental problems that are occurring today.
People are deforesting the planet for thousands of years, primarily to clear land for crops or stock. though tropical forests square measure for the most part confined to developing countries, they square measuren’t simply meeting native or national needs; economic economic process means the wants and desires of the worldwide population are bearing down on them also. Direct causes of deforestation square measure agricultural growth, wood extraction (e.g., work or wood harvest for domestic fuel or charcoal), and infrastructure growth like road building and urbanization. seldom is there one direct cause for deforestation. Most often, multiple processes work at the same time or consecutive to cause deforestation.The single biggest direct cause of tropical deforestation is conversion to cropland and pasture, mostly for subsistence, which is growing crops or raising livestock to meet daily needs. The conversion to agricultural land usually results from multiple direct factors. For example, countries build roads into remote areas to improve overland transportation of goods. The road development itself causes a limited amount of deforestation. But roads also provide entry to previously inaccessible—and often unclaimed—land. Logging, both legal and illegal, often follows road expansion (and in some cases is the reason for the road expansion). When loggers have harvested an area’s valuable timber, they move on. The roads and the logged areas become a magnet for settlers—farmers and ranchers who slash and burn the remaining forest for cropland or cattle pasture, completing the deforestation chain that began with road building. In other cases, forests that have been degraded by logging become fire-prone and are eventually deforested by repea...
Biodiversity conservation is about saving life on Earth in all its forms and keeping natural ecosystems functioning and healthy. Biodiversity is being depleted by the loss of habitat, fragmentation of habitat, over exploitation of resources, human sponsored ecosystems, climatic changes, pollution invasive exotic species, diseases, shifting cultivation, poaching of wild life etc. Since the human beings are enjoying all the benefits from biodiversity, they should take proper care for the preservation of biodiversity in all its form and should prevent the degradation as well as the destruction of the habitats thereby maintaining the biodiversity at its optimum level which will ultimately conserve the biodiversity for the future generation.
The Human Impact on Rainforests Human Impact on Rainforest is it a necessity? Rainforest are the beautiful gift of Mother Nature. It consists of the most magnificent species and plants in the world. 4.2% of the world’s animals live in the rainforest. This statistic it self shows how bad it would be to destroy such essential part of the worlds biodiversity.
Simply speaking, rainforests are basically the foundation of the earth. The most important role that rainforests play is ‘the lungs of the earth’. This is extremely vital to the earth’s survival as the trees and plants absorb carbon dioxide which they use to help grow and let out oxygen which we need to live. This system is known as the carbon-oxygen cycle and with numbers of rainforests declining, it is highly threatened. The largest rainforest in the world, the Amazon, alone is known to produce half of the world’s oxygen. A break down in the carbon-oxygen cycle means that we will not only have less oxygen, but an increase in carbon dioxide which eventually leads to global warming. This occurs as carbon dioxide traps heat which actually keeps the earth warm, with the right amount of carbon dioxide that is. This is called the greenhouse effect and occurs naturally however due to decreasing number of trees, there is more carbon dioxide than needed which traps extra heat making the earth hotter than needed, this is known as global warming which also causes a rise in sea level.
Tropical rainforests have many species of plants and animals. They are very interesting and many scientists today study it. Rainforests are an important part of our environment and it is important for us to protect it. That’s why we have to stop global warming.
Today deforestation is all over the world and it is increasing. Our forests are disappearing at a very fast rate. Most people, when they think of deforestation, think of the Amazon Rain Forest. However, this is not the only place that deforestation occurs. Deforestation also occurs in East Asia, Indonesia and the Congo. China has only 2% of its forests left. Some of the last of the world’s rainforests are in Indonesia, Papua New Guinea and the Amazon. Deforestation is a big problem. It not only affects the world around us, bu...
Recently over the years elephant populations have drastically declined. This is due to human encroachment on their habit and poaching. Demand for ivory has increased the number of poaching kills in Africa. In 1988 congress passed the elephant African Elephant Conservation Act which placed a ban against illegal ivory imports and authorizes government funding for elephant field conservation projects. Although some African countries have initiated African elephant conservation programs, many do not have the sufficient resources to properly manage, conserve and protect their elephant’s populations. Unfortunately, we are possibly undergoing “the greatest percentage loss of elephants in history” (Ruggiero). Without the proper conservation of elephant survival we will see a drastic shift in the environment.
In our world today we have approximately 26,021 endangered species. Endangered species are organisms that may possible become extinct. The term 'endangered species' refers to all species that fits this description. However some conservation biologists and scientists normally use the term ‘endangered species’ to refer to species that are put on the IUCN(International Union for Conservation of Nature)Red List. Many factors can be looked at when considering the conservation status of a species. Factors such as human threats or environmental threats can cause a species to become endangered.
Biodiversity refers to wide diversity found in the living components of the earth which refers to the numerous varieties of flora and fauna including those of microorganisms too. The interaction of biotic and abiotic components of the ecosystem is very important aspect of life on earth. Biodiversity helps us to understand the variations among species and also how life originated on earth. Its study helps us to understand the inter-relationship between various forms of life and their adaptation to different conditions.
NEED AND PURPOSE FOR CONSERVATION OF BIODIVERSITY: Biodiversity, a contraction of “biological diversity,” generally refers to the variety and variability of life on Earth. The very existence of human species and sustainable development depend on biodiversity conservation, therefore the need for conservation of biodiversity is basically for this reason that all living creatures need other creatures and plants in one way or the other. At least 40 per cent of the world’s economy and 80 per cent of the needs of the poor are mainly derived from biological resources. Biodiversity is necessary for our existence as well as valuable in its own right as it provides the fundamental building blocks for the many goods and services which are essential
