Humans have many effects on the ecosystem that lower population and communities of other organisms. Although society cannot prevent all actions other people do towards the ecosystem, people can prevent a few in their day to day lives. The ecosystem is very important to human life, as it gives the atmosphere oxygen to breath. Over many years of careful examination, scientists have noticed huge changes in the ecosystem due to human actions, concluding with damaging results. Therefore human actions have many effects on the ecosystem.
First, deforestation is one main cause that affects the ecosystem. Deforestation is clearing land of trees and plants in an area. Logging companies and lumberjacks are constantly clearing forests for money, which result in wiping out communities and habitats for other organisms. When a work force or group of people start to clear out a forest, they are taking all food and resources from organisms that live in the region and wiping out the homes of many insects and other tree dwellers.
Another main cause for negative effects on the ecosystem is pollution. There are many types of pollution, simply including water pollution, air pollution, and land pollution. Pollution is caused on a day to day basis, whether it be littering or even burning coal. Littering can harm organisms by entanglement or toxic hazards. Burning wood and other sources like coal cause air pollution which results in breathing hazards and depletes the forests. Water contamination is one of the most devastating forms of pollution that affects the ecosystem, primarily because all organisms need water to survive. Agriculture is a main factor of water pollution because pesticides, fertilizers, and other toxic chemicals are washed downstre...

... earth and ecosystem. These groups and or organizations get word to the people about what is going on in the world by telling and showing people the causes and effects of our harmful and helpful actions towards the ecosystem and try to get others to help their cause for a better earth. Another positive effect of human actions, relating to awareness, is environmental management. Environmental management’s main cause is to lessen disturbances and restore equilibrium to the ecosystem (“Positive”). Another reason for environmental management is to manage resources taken from the ecosystem and improve our input and output ratio to be more efficient. Preservation is another positive effect of human actions. Preservation entails National wildlife refuge systems, along with preserving unique habitats for rarer species to thrive, reproduce, and prosper safely (“Positive”).
The main reason deforestation happens, is because of farming. They need to clear out land in order to plant crops and vegetables. Another loss from deforestation is that many animals lose their habitat. The loss of animals habitats will lead to migration, or possibly even extinction. And when this happens this will ruin the food chains which will affect even more animals.
Ecosystems are the basic biological units of ecology, and consist of biotic organisms and their interactions amongst other living organisms, as well as the surrounding abiotic environment (Putman and Wratten 1984). One facet of ecosystems that is less-often mentioned is the process of decomposition, as it many may view it as an unclean, unpleasant process that occurs after an organism has ceased to exist. To those with an ecological framework, however, decomposition is viewed as the opposite – an interesting, intricate process teeming with biological activity and life (Swan and Kominoski 2012). What is decomposition? Formally, decomposition is defined as the process to which complex organic matter is broken down to its basic constituents (i.e.
Discerning the spatial patterns of biodiversity and understanding their ultimate (why) and proximate (how) causes is very dear to biogeography and is one of the key concepts of Macro ecology. Some places on earth contain more species as compared to others. All species occurring at a given space and time either originated (speciated) there or dispersed and arrived from another place and settled there. Biogeographers try to understand the past and current distributions of species by incorporating historical, evolutionary and ecological factors. Earlier biogeographers or the ‘naturalists’ in their sacred quest to serve ‘the creator’, travelled to various parts of the world and imparted valuable knowledge about the diverse patterns and processes of nature. Linnaeus (1743), on the one hand, hypothesized that early Earth was filled with water except for it’s highest mountain top i.e., Mount Ararat which was known to be the site of paradise and as the sea level dropped the exposed land was colonized by plants and animals that migrated down from high elevational zones of Mount Ararat whereas Willdenow (1805) hypothesized that within each geographical region of the earth, plants and animals were first placed and later survived the great flood on many mountain ranges (Lomolino,2001). Von Humboldt and Darwin in the South American Andes and Wallace Southeast Asian islands noticed the decreasing trend in elevational species richness patterns (McCain and Grytnes, 2010). Later work done by Grinnell (1917), Whittaker (1952), Terborgh (1977, 1985) on elevational species richness became accepted and set a established pattern for all species for more than two decades (McCain and Grytnes, 2010). However current researches on elevational gradients are...
There is no such thing as just changing something from one part and not having its effects distribute throughout the entire ecosystem. As an ecosystem continues changing and evolving, so will the organisms living around or in it. We must adapt to the environment or we will become extinct, unable to adapt into the rapidly changing environment we live in. Althout human impact on an environment may benefit us, it can also be harmful to nature. By taking care of what we do to the environment, we can prevent future negative changes in the environment and preserve earth’s natural state.
By definition, deforestation is the permanent destruction of forests in order to make the land available for other uses. Such as the conversion of forestland to farms, ranches, and urban use. Food and Agriculture Organization of the United Nations has reported that an estimated 18 million acres of forest are lost each year and about half of the world's tropical forests have been cleared. Also, according to Bastien Sachet, “…tropical deforestation is responsible for approximately 20% of world greenhouse gas emission…Every year, 13 million hectares of the world’...
There is no hesitation when it comes to whether humans impact the global environment. However, it is questioned in whether human’s ecological footprint is either negatively or positively impacting. In clear perspective, humans share from both sides and their ecological footprint is noted towards whether it will benefit or harm the environment around them. Topics such as overpopulation, pollution, biomagnification, and deforestation are all human impacted and can harm the environment, but some include benefits into helping the world around us with solutions to their problems.
“The Earth is 4.6 billion years old. Scaling to 46 years, human have been here 4 hours, the industrial revolution began 1 minute ago, and in that time, we’ve destroyed more than half the world’s forests.” - Unknown. One major environmental problem in our world is deforestation - what is that, you ask? According to the Merriam Webster Dictionary, deforestation is the action or process of clearing of forests. Some consequences of this include a large contribution to global warming and climate change (about 1.5 billion tons of carbon dioxide each year), loss of biodiversity especially in tropical rainforests, and the extinction of many known or yet to be discovered species. But, through some Debt-for-Nature Swaps, leaving forests
Deforestation began with man’s ability to manipulate his environment. Wood has always been a primary source for shelter and has been affected by human expansion. As the worlds population grew, so to did the need for wood to make housing. As cities grew so did the demand for space to accommodate the growing population. Throughout history and even today, man has manipulated the environment affecting it’s resources.
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.
According to World WildLife Fund, many ecosystems around the world are being destroyed, eliminating many plant and animal species that inhabit them (“Pollution”).
Pollution is causing the destruction of environments and habits resulting in many adverse affects. The types of environments that are heavily damaged by pollution is normally freshwater ones. Polluting factors such as untreated sewage, mining waste, acid rain, fertilizers and pesticides
= == In this project I aim to explain the contributes to the environment by the actions of humans and display the consequences. I am going to divide the project into different sections and then sub sections to make the project easier to navigate around and keep the information in relevant sections. · Section 1: HABITAT REDUCTION BY HUMANS.
Scientists have begun to say that we have to do more to protect our ecosystem, because our very existence is depending upon it. When the ecosystem is not functioning properly the continuation of plant, animal and human life ecosystems would be impossible. Life cycles can not function without ecosystems. The ecosystem provides us with clean air, water, habitats for fish and other services. They also aid in the mod...
There are lots of environmental issues going on globally. The earth faces problems such as pollution, global warming, waste disposal, and loss of biodiversity. These are just a small amount of issues out of the so many. These environmental problems pose an abundant amount of risk to the health of humans and animals. There needs to be a solution to all these problems and that is by informing others, so that way everyone can make the environment a better place.
Biodiversity is so important that if any chain or link is disturbed then the whole system will come to a halt. Biodiversity also boosts ecosystem productivity and if it declines automatically our ecosystem also declines as both are interdependent upon each other, where all the species play an essential role in the way ecosystem functions, so local and global species loss could threaten the stability of the ecosystem services on which humans depend. This is an interesting topic as well as a global issue concerning the whole human civilization and their existence. . The said issue as well as many other issues regarding our natural processes cannot be neglected as our present and future depends entirely on the sustainability and growth of this ecosystem and biodiversity. Our ecosystem completely depends on the way biodiversity functions. This is the reason I have chosen this topic and gathered information about how it e...
