Welcome - Human Resources
The ecosystem encompasses all living things animals, plants and microorganisms and non-living things earth, climate, soil, sun, weather, and atmosphere. All these components make up the environment, and they are critical for the natural and normal functions of all the activities on the planet.
In short, they are the foundations of the ecosphere and influence the health of all the systems on earth. For example, ecosystems determine the niche played by each and every organism and how they interact with non-living things such as water, light, air and climate.
Due to this intricacy and interconnectedness, any activity that disturbs the natural balance of these components affects the ecosystem. Anthropogenic activities top the list as there are numerous human actions affecting this balance.
This article outlines various human activities affecting an ecosystem. The population growth rate is hence driving the world to clear forests in order to create more room for agriculture. The result is devastating, as discussed below:.
Forests are critical habitats for wildlifeand as ecosystems supporting the intricate relationship between the living and non-living things, they have been adversely affected by agricultural practices.
A larger percentage of Europe, for example, human activities on natural resources, was densely covered with temperate forests, but with time it has been cleared to make room for farmland, human activities on natural resources. Population growth-influenced deforestation is to blame for three billion tons of CO2 released into the atmosphere each year, which is equivalent to the destruction of 13 million hectares of land annually as put forward by the Union of Concerned Scientists.
This rate of deforestation affects the ecosystem by raising global temperatures and disrupting the cycle of condensation and evaporation. Various ecosystems, human activities on natural resources, such as the Polar regions, are, in turn, affected by the rising global human activities on natural resources and changes in the atmospheric water cycle.
The injection of vast amounts of phosphorous and nitrogen nutrients into natural soils, lands and water systems due to fertilizer use have created far-reaching effects, altered ecosystems, and rapidly expanded aquatic dead zones. Deforestation occurs when a forest or stand of trees is removed, human activities on natural resources, converting the land to a non-forest use.
This changes the ecosystem drastically and human activities on natural resources in a dramatic loss of biodiversity. With an exponential expansion in human beings, more food, materials, and shelter are being manufactured at stupendous rates, mostly stemming from forestry.
Deforestation can be the result of timber harvesting or of clearing land for agricultural, commercial, or residential use. According to international dataan estimated 18 million acres of trees are clear-cut each year to make way for new development and wood products- that human activities on natural resources just under half of all the trees on the planet since the industrial revolution began. With trees being one of the largest producers of oxygen, and with millions of different species that live in forests, deforestation is a major threat to their survival and a big conservation issue.
It increases greenhouse gases within the atmosphere, which leads to further global warming. The loss of biodiversity and trees alters the ecosystem and can result in aridity and erosion. It also results in climate change and extinction, and it can lead to desertification if on a significant enough scale. The social impacts can include the displacement of indigenous peoples. Recent studies have attributed deforestation to the increase of wildfires in areas like the Amazon Wildfires are equally destructed even more so, displacing both people and entire species.
Overpopulation has grown into an epidemic since mortality rates have decreased, medicine has improved, and methods of industrial farming were introduced, thus keeping humans alive for much longer and increasing the total population. One of the most severe effects of overpopulation is the degradation of the environment.
Humans require lots of space, human activities on natural resources, whether it is for farmland or industries. An increased population results in more clear-cutting, resulting in severely damaged ecosystems. Another issue is humans consume large amounts of resources for their own needs. Some examples include the mining of natural resources like coal, the hunting and fishing of animals for food, and the clearing of forests for urbanization and wood use.
The extensive overuse of nonrenewable resources, like fossil fuels, can cause great harm to the environment. The larger the population, human activities on natural resources, the more fossil fuels will be used, and this results in copious amounts of carbon dioxide into the air- threatening the extinction of thousands of species.
The invention of plastic has created one of the most problematic pollution problems ever witnessed on the face of earth. Waste plastic is everywhere on earth, even in the oceans. Plastics remain in the environment for thousands of years and have long-lasting consequences on the fragile ecosystems and regulatory cycles.
Plastics floating in the world oceans are estimated to amount to 5. They can also cause rapid cell division, which may result in cancers. Above all, since the plastics remain in the oceans for years and years, they can ultimately reverse ecosystems with damage costs approximated at 13 billion US dollars in a year. Wildlife is most affectedand some have even died after consuming unusually great amounts of plastics.
A whale found dead on the coast of Scotland in Junefor example, had consumed nine pounds of plastic, human activities on natural resources, causing a blockage in its digestive tract.
To make the matter even worse, more than 4, cases of fish with plastics in their bodies have been recorded worldwide. The emission of carbon dioxide and other greenhouse gases, namely methane and hydrofluorocarbons HFCsare human-induced through the combustion of fossil fuels and the use of man-made products. In a bid to generate energy, the world has continued to depend on carbon-rich fossil fuels, namely gas, oil and coal.
The combustion of these fossil fuels to produce energy in the years between and produced approximately billion tons of carbon dioxide into the atmosphere. Today, human activities on natural resources, carbon dioxide levels are said to be surprisingly higher than ever in history. As a result, global temperatures human activities on natural resources on the rise contributing to sea-level rise and extreme human activities on natural resources events like heatwaves, flooding, tsunamis, and droughts.
The sea-level rise and extreme weather events have, in turn, altered ocean and land ecosystems, impacted food chains and biodiversityand intensified desertification. Water pollutionclimate changeoverfishing and acidification of marine waters are the repercussions of human activities that have caused the destruction of coral reefs. Experts say that one-fifth of global reefs are already destroyed and one-fourth of reef species might go extinct by Further, the livelihoods of about million people globally depend on the coral reefs for survival because these are the critical growth and reproductive areas for many fish species.
The reefs simply provide shelter and productive grounds for aquatic species, and upon their degradation or destruction, they stop providing the essential materials for a vibrant interconnectedness that is necessary for supporting specific aquatic ecosystems. The reason for this is that the destroyed coral reefs are mainly dominated by jellyfish and bacteria, which limits the capacity for sufficient regulation of energy and nutrients.
Black carbon particles have been generated by human activities for hundreds and hundreds of years. Black carbon particles are materials emitted into the atmosphere as smoke and are produced from cooking with solid animal fuels, burning firewood, diesel car exhaustsand the burning of trees.
The presence of these particles in the atmosphere creates a heat-absorbing layer that gives rise to increased global temperatures, thus compounding the global warming effect. Nations heavily dependent on diesel fuel, coal, and burning of wood or cow dung fuel for heating and cooking are the biggest emitters of black carbon. Black carbon has also changed weather patterns and reduced rainfall in West Africa and South Asia, according to various scientific reports.
It has also played a role in the melting of the glaciers in the Himalayan region, threatening ecosystems and water supplies for millions of people. Various anthropogenic activities have heavily destroyed freshwater supplies such as rivers, streams, human activities on natural resources aquifers.
Intensive agriculture is a leading cause on account of the large amounts of chemical fertilizers, herbicides and human activities on natural resources agrochemicals that find a way into waterways.
Intensive agriculture is also water-intensive, thus over-drains rivers and degrades critical freshwater aquifer recharge areas. The construction of man-made dams and water-diversion for irrigation or during infrastructural construction has also made the natural flow of water in rivers and streams inefficient. As such, these practices have gradually destroyed freshwater recharge capabilities, increased salt intrusion, and changed local weather patterns, in turn affecting local ecosystems such as forests, lakes and wetlands.
Increased salt concentration in lakes has made it difficult for some fish species to survive. Overhunting and overexploitation of natural resources through activities like overfishing and mining have caused a reduction in the number of varied plant and animal species.
In other words, the diverse existence of animal and plant species in different habitats has been widely affected by overhunting and overexploitation. These human activities do not give room for the replenishment, growth, or new development of already exploited or harvested products. Overhunting can cause extinction, human activities on natural resources, destroy natural reserves and breading areas, and affects food chains.
Therefore, whenever any living thing or native species that play a part in an ecosystem is taken away in large quantities or becomes extinct, the entire ecosystem suffers and can be permanently altered. Also, when humans convert forests into farmlands or river basins into mining areas, the areas are made harsh for the survival of animal and plant species. GMOs also come with the advantage of being human activities on natural resources tolerant of extreme temperatures, the ability to flourish with less water, and better ability to resist parasites and diseases.
On the other hand, GMOs also come with new biological elements that can impact natural ecosystems in numerous ways, as reported by different environmental groups. One is changing the natural ways of competition or predation. Secondly, soil microbial populations regulating the flow of phosphorous, human activities on natural resources, nitrogen and other human activities on natural resources elements can equally be impacted, human activities on natural resources.
Thirdly, genetic materials can be transferred to other native populations. Invasive species are brought on by transporting species either intentionally or accidentally from other areas of the world. This can be devastating to existing species as invasive species are introduced on a timescale much more quickly than typically would happen with evolution over longer time periods.
This can include outcompeting native species in the ecosystem, leading to the decline or extinction of local species and overpopulation as these invasive species may not have any predators in this new ecosystem. Human activities on natural resources also can be a major economic cost.
The zebra mussel provides an invasive species that has had significant economic impacts. The zebra mussel is native to lakes in Russia but was accidentally introduced in the United States and Canada through the ballast water of commercial ships that were transporting goods to the Great Lakes region in the s. They have been spreading ever since and have recently been found in lakes in Massachusetts; they attach to recreational boats and are transported wherever the boat may go.
They colonize rapidly and have covered the undersides of docks, boats, and other marine structures and can grow so thick that they block municipal water and hydroelectric pipelines.
