Human Impact on the Environment
About three hundred years ago there was a definite spurt in the population of the human race. This was brought about with advancements in sanitation and technology, as well as a dramatic fall in the death rate. By around 1850 the world's population had grown to about 1 billion and by 1930 it had risen to 2 billion. The current figure is around 6 billion and at this rate the United Nations estimates the population will be at about 9 billion by 2054. This would be a 900% increase in just 200 years.
This increase in population has meant that the world's resources have been put under a great strain in order to sustain the human race. But it has only been in recent

The culture of many forest-peoples has been destroyed and deforestation also affects the livelihoods of between 200 and 500 million people, who depend on the rainforest for their shelter and food. Deforestation may also lead to global climate imbalances. There is also a major problem when it comes to carbon storage. With the removal of the trees excessive carbon dioxide levels in the environment may lead to global warming, with many problematic side effects. While deforestation is now viewed as problem, historically it was considered to assist natural development and so now some countries rely on the rainforest for income and the problem will continue whilst they have no alternative.
Another problem caused by humans is as a result of the increase in demand for extensive farming throughout the world. In order for crops to be grown trees have to be cut down and I have explained the effects of this already. As well as deforestation, agriculture has also called for the use of fertilisers and pesticides. Fertilisers (and raw sewage) cause eutrophication. Eutrophication occurs when farmers are forced to increase the productivity of their crops and so use fertilisers. These fertilisers run off the land into the waterways and increase the levels of nitrates and phosphates in the water. In turn this increases

Cutting down of trees is one environmental issue that has plagued the world for the past few decades. The reason for this is the fact that there has been an increased use of timber and an increase in population and the need for human settlement has ensured that an increased number of trees have been cut down.
Environmental scanning can be viewed as a way of acquiring information about outside events that can aid organizations in first identifying potential trends, then interpreting them
The POET model talks about how the many different primary drivers there are present in society today that aide the increase of the human impact upon the environment. The primary drivers discussed in this model are population growth, organization of governments, the environment, and the technology of today. Each of these has some varying effect upon the environment. These primary drivers each have arguments and examples from throughout history that can show how great of an influence they may have on human impact upon the environment. One aspect that is sometimes forgotten about it the concept of how values effect the drivers within the POET model. Values can certainly effect the increase or decrease in population and can even effect technology that is produced around the globe. Author Lynn White begins to go in depth about the topic of how religious values have shaped the science and technology that we know today in his article titled “The Historical Roots of Our Ecological Crises”. White delves into the history of Judeo-Christianity and the influence this religion has had upon the world of science and technology.
How many trees are cut down a year? Every year nearly 900,000,000 trees are cut down to provide raw materials for American paper and pulp mills.Have you ever wondered what a world without trees would look like? Close your eyes, and try to imagine a desolate Earth. There'd be no more paper, and everyone would have to resort to technological use that is, if anyone was left.Trees are a crucial factor to our existence not only because they produce paper, lumber and chewing gum, but because they serve an important role in the carbon cycle. And because of our ever-increasing population of 6.7 billion, that seemingly distant future is nearing each and every day. People have proposed many solutions to this environmental issue called deforestation, including either shipping everyone to the Moon or...to just stop cutting trees! Even if our species survived the devastation of deforestation, life as we know it would be very different from now in 2016, where only half of the world's forests are gone. Scientists speculate our great-grandchildren might not even have the chance to visit the great Amazon rainforest in 50
“Let every individual and institution now think and act as a responsible trustee of Earth, seeking choices in ecology, economics and ethics that will provide a sustainable future.”
The affect of environmental issues occur everyday and in particular deforestation is becoming a highly ranked subject. From animals to the human race, the alacrity of trees that are cut down affects every individual in a variety of ways. Not only do people need to help the planet but they need to help themselves and further generations to come, such as children and grandchildren because these natural resources that are being taken away from society are as well shaping the future. For comprehensible reasons, forests use to make up the world, until man made creatures started to destroy and destruct the most important supply to human kind which are trees. Trees are crucial to every living entity for the reason of providing oxygen to all.
In recent years, the controversial subject of global warming has been more predominantly brought to our attention. Is the threat of global warming real? Is it man-made or is this just a natural cycle of earth? Does it really affect earth’s inhabitants? Should action be taken against it? If so, what kind and to what extent? It cannot be only a coincidence that the alarmingly rapid climate change coincides perfectly with the increased amount of pollutants that humans release into the environment. The once stable climate has in recent years begun to skyrocket, thus altering the delicate structure of earthly life. This proves to be hazardous to the future of the planet; some people worry that many of the resources the environment provides that
What we are doing to stop burning fossil fuels and help the environment is everything we
The scale and pace of change is dramatic; for example, the extinction of species is occurring at around 100-fold pre-human rates4. The population sizes of vertebrate species have, on average, declined by half over the last 45 years5. More than 2.3 million km2 of primary forest has been felled since 20006. About
The Wilderness Society’s Governing Council states that “No other ecosystem in the world can store as much carbon as do these forests, and it’s a capacity they have not yet begun to reach” (Bert5). Trees are very important to all of the living species. The cutting down of the trees is now nearly 4 billion trees or 35% of the total trees cut around the
Nearly everything that a human does is in response to the environment. Our lives are defined by what is around us and what we find in front of us, whether this means accepting, dealing with or changing it. This has been the pattern since primates first stood up and became Homo erectus, and has continued until we considered ourselves doubly wise. The shape of the land affected where humans moved. Weather was something with which to contend. Fire affected humans until they conquered it – and herein lies the core of the relationship. The earth affects humans, and humans affect it back, viewing characteristics and patterns as problems and challenges, and finding a solution.
Deforestation for agricultural purposes and the expansion of human habitats is happening around the world. This
Environmental problems are something which belongs to nature or known as “Mother Earth” [13]. Nature was created to help people survive from gathering foods until build a house. This phenomenon happens continuously without thinking how much damage that nature has because human’s fault. Nature gradually becomes worse and animal’s life in danger. People who are aware of the importance of nature react. Those people do several ways to save the environment. Although these efforts can return back the environment, these efforts only can be hold temporarily. This problem happens because those people who are aware of the environment only slightly; for remaining, there are people either do not know or do not care about the nature. People’s efforts
According to Mintzberg, the environmental school of thought is a strategy dealing with the forces outside the organization. Unlike the other schools in his book, Strategy Safari, the environment plays a central role in the strategy formation process alongside leadership and the organization where the organization becomes subordinate to the external environment. The environmental school assumptions are that during the formative period of the organization the company shapes itself in response to the environment, but after that period is increasingly unable to respond to the environment. Moreover, the organization long term survival depends on the early choices made during its formative period. Over time, Mintzberg states, leadership becomes
