Environmental Issues Development Due to Human Activities

Environmental issues development due to human activities

Introduction:
There are a lot of environmental concerns, which occurs due to the human activities. So it
elaborates clearly that human activities impact in a negative manner to the environment. Two
major environmental issues are investigated in Canada. These issues are the Green gas
emission and the climate change due to various human activities. However, all the
environmental issues are having some relation with each other, as due to GHG and many
other factors, climate change introduces as an issue. Due to this climate change, hurricanes
and many other environmental issues introduce. So, in current research, two main
environmental issues is analysed as Greenhouse gas emission and climate change. In this
research, these environmental impacts are analysed due to various human activities. This
research also investigates the long term and short-term scope of these issues impacts on
environment. Along with it also elaborates the mitigation strategies of these environmental
issues.
Humans impact the physical atmosphere in several ways such as pollution, overpopulation,
fossil fuel and deforestation etc. these variations introduces soil erosion, climate change,
deprived air quality and deprived water quality etc. these negative impacts can affect human
behaviour by rapid mass migration.
Human require space for living and industrialization which takes almost tons of space. An
increment in the population shows the outcome as a lot of forest cutting which results a
severely damaged ecosystem. By which the level of carbon dioxide increases and it reduces
the air filtration.
Global warming is arguably a major cause of environmental impact. The highest causes
emanating by CO2 levels from respiration to much more detrimental causes such as
deforestation and burning fossil fuels. (Dearden, & Mitchell, 2016)

Due to all these reasons, humans are constantly enhancing carbon dioxide levels worldwide
yearly basis. The increment of carbon dioxide emissions has contributed to the planet’s mean
temperature enhancing almost an entire degree.
Analysis:
Environmental issues:
In Canada, two major environmental issues are the greenhouse gas emission and the climate
change. Both issues impact the environment in many ways. Human activities are the main
sources of these environmental issues.
Contribution of human activities towards these environmental issues:
The climate change guidelines by the current intergovernmental panel elaborate that national
greenhouse gas inventories are based on a statement. This assumption shows that entirely
releases and the eliminations in land management are produced by the humans (Kurz et al.,
2018).
The graph shown in figure.2, elaborates about the sector which contributes in greenhouse gas
emission. The graph clearly shows that the gas, oil and the transportation sectors are the
biggest contributors of national greenhouse gas emission. Another graph is also showing the
highest contributors for GHG emission
In 2015, Canadians produced over 720 Mt of GHG or greenhouse gas emission ("Where Do
Canada's Greenhouse Gas Emissions Come From?", 2012).

Greenhouse Gas Emissions Come From?", 2012).

Figure.2 Sectors of Canada’s GHG emissions retrieved from ("Where Do Canada's
Greenhouse Gas Emissions Come From?", 2012).
Human activities are the major reason of climate change as persons burn the fossil fuels and
they transform land from the farming forest. Due to the deforestation, lot of harmful gases
does not convert into the oxygen for making the pure environment. Hence, it enhances the
climate change.
Burning fossil fuels produces CO2, which is a greenhouse gas because it creates the
greenhouse effect. This effect makes the earth warmer by which the climate change occurs.
(Climate Change Canada, 2019)
Short-term and long term impacts of environmental issues:
In Atlantic Canada, the smaller rural coastal communities are susceptible to the impacts of
ecological changes. Maximum number of hurricanes is confiscated at the seashore area. It
causes a large amount of physical destruction and it affects the socioeconomics of these
societies which are collected of an elderly population. The analysis is based on the literature
of an interview in 2011-2012, which elaborates about the 2010 winter storms in Atlantic
Canada. This interview depicts the socio-economic and physical influences disturbing 10
seaside societies. These 10 seaside societies are situated in the countryside of Prince Edward
Island, New Brunswick, Quebec etc. (Vasseur, Thornbush & Plante,2017).
The enhanced anthropogenic activities and climate change are assumed to raise the possibility
of presenting NIS or nonindigenous classes into the Arctic. Several overview actions are
accredited to various likely paths. It is a prediction that the arctic waters will be warmed in
near future which will provide the opportunities of aquaculture and fishing activities

expansion. It increases the hazard of NIS overviews which are related with these pathways
(Chan et al., 2019).
On the other hand, there are currently 80 species of mosquitos in Canada. By which, several
viruses have been originated to cause human contaminations in Canada including North
America. Over the last 20 years, the occurrence of these virus detected disease has increased
nearly 10% in Canada due to the climate change (Ludwig et al., 2019).
Entirely, it is being observed that the existence of climate change is due to the human itself.
The analysis shows the various possible impacts of the climate change in the forest
ecosystem. Due to this climate change issues, many disaster came across the world as floods,
storms etc. (Ameztegui et al., 2018).
Mitigation strategies for the environmental issues:
The aim of this study is to evaluate the energy usage mitigation approaches by which it can
be possible to mitigate such kind of environmental issues. A bottom-up resource arrangement
model is developed. This model is applicable for the oil sands removal and its advancement
process in Canada. This model is based on an energy accounting based scenario which
simulates the energy demands and oil sand supply from 2007 to 2050.
By implementing this model, the energy usage reduction is calculated on the basis of
greenhouse gas emission reduction about 86 million tonnes by 2050. Hence, there is a higher
possibility of reduction in energy consumption by 7-8% by 2050. So this model is
supportable to environment as well as in cost saving initiatives (Katta et al., 2019).
The highest mitigation possibility is achieved through the harvest utilization improvement by
utilizing the harvest residues for bioenergy and by shifting the commodity mix to the longer

lived wood products. The greatest cumulative mitigation of 421MtCO2 for British Columbia
is estimated which shows the highest domestic mitigation during 2017-2050 by employing
this strategy portfolio.it would contribute approx. 35% of GHG reduction target by 2050 (Xu
et al., 2018).
There are several steps by which it is possible to mitigate the environmental issues as Climate
change. These are shown below:
 Minimizing methane emissions by livestock systems: it is the mitigation technique
which shows the result in better irrigation water efficiency. It can also share new
sources of income by enhancing the performance of cultivated agro-ecosystem.
 Reduction in N2O emissions: it improves the ground water quality and it reduces the
loss of waste management system, biodiversity and biogas utilization and capture. By
reducing the CH4, it is possible to enhance the demand of farmyard manure and it will
create the income for the animal husbandry sectors.
 Land restoration by graze control: it can lead the soil carbon sequestration with the
positive impacts on the livestock productivity. It reduces the desertification.
 Practicing Agroforestry: it promotes the soil carbon sequestration, it also improves
the agro-ecological function and resilience for the extreme climate by enriching the
soil water retention and soil fertility.
Conclusion:
Human activities such as fossil fuel combustion etc. are altering the climate change. Human-
driven changes in the usage of land also alter the climate. These changes can be termed as
deforestation, shifts in vegetation patterns and urbanization etc. The outcomes of these
changes can be presented as the reflectivity of the earth surface. The major reason of the
climate change is human and the solution is also reflected within the human domain.

The climate change impacts the ecosystem in various countries in terms of an increment in
temperature. The things in which human depend upon are water energy, wildlife,
transportation, agriculture, ecosystems and human health are experiencing the impacts of a
changing climate.
Human impact on atmosphere in numerous ways, some common effects include water
quality, conservational contamination and greenhouse gas releases, reduction of natural
assets and impact to climate change.
