THE EFFECTS OF MAN'S ACTIVITIES ON ECOSYSTEM
The concept of ecosystem is possible at several scales of magnitude.From multicellular organisms such as insects (arthropods), animals ( Animals and metazoans) or plants (Vascular, herbaceous and flowering plants) to lakes, mountain ranges or forests to the planetEarth as a whole.
Ecosystem, it is a community or group of living organisms that live in and interact with each other in a specific environment. Without an environment there can't be ecosystem because Environment consists of living and nonliving organisms.
The impacts on man's activities on land and in the water can influenceecosystems very importantly or profoundly.
The effects of man's activities on ecosystem could be in positive and negative ways.
The man's activities on biological and physical environment are in many forms. They are: Deforestation, overpopulation, burning fossil fuels, and environmental pollution. These changes have initiated and caused climate change, poor air flow, soil erosion and unwholesome water for drinking.
These negative activities on ecosystem can affect human populationand behavior by causing migration or competition.
The anthropogenic impact on the organisms and their environments includes biophysical environments and to ecosystems ,biodiversity, and natural resources caused directly or indirectly by humans, including global warming, environmental degradation (such as ocean acidification, mass extinction and biodiversity loss, ecological crisis, and ecological collapse.
Factually, the negative effects of man's activities on living organisms and their environment have caused serious dangers to our socio-economic, agricultural, and ideal world. We now experience some negative effects that could make lives deleterious for living.
In other way, man's activities are threats to biodiversity. These activities threaten biodiversity because the more people there are, the more these displace other species and reduce species richness.
The extensive overuse of nonrenewable resources like fossil fuels cancause great dangers to the living organisms and their environment.
The recycling products made from nonrenewable resources (i.e plastic, which is made from oil) is one way to reduce negative effects(i.e resource exploitation) of man's activities on ecosystem.
In addition, humans may consciously or unintentionally introduce a non-native and invasive species to an ecosystem, exposing the living organisms to dangers.
The current climate change we're facing is caused by the increase in temperature. Man's activities are changing the Earth's atmosphere faster than it has ever changed its history.
For instance, the burning of fossil fuels in industry and by vehicles releases carbon monoxide and green house gases into the atmosphere.
When climate change, and other effects affect an environment so much that it is unable to sustain organisms, they must adapt, relocate or face extinction.
In conclusion, Biodiversity loss as one of the effects of man's activities on ecosystem may be a large scale problem.
As scientists in the making, if we improve on smaller efforts, such as reusing or recycling wastes, even purchasing sustainable foods can have a culminating effect. That is, if each of the biological science students did these things, even just a little, they would add up and help reduce biodiversity loss as a result of man's activities on ecosystemwhich will later show positive effects people's lives.
Biologically, our aim is to reduce dangers, either caused by man's activities or by microorganisms to ensure healthy ways of life.
With an healthy Environment, we experience longevity in biological lives of the people. That's why we always say "Biology....... Lives!"
