Population is defined as all the inhabitants of a particular town, area, or country. From the year 2012, the population of Canada has increased by 4.4% (Statistics Canada, 2016), leaving free land to become developed for our needs. With population growth, comes a different way of living for everyone. The impact of human population growth has largely affected the health of the earth’s ecosystem from an environmental point of view, challenging wildlife, climate, and the environment.
Population growth is the largest challenge that wildlife faces in their struggle to survive. Houses, buildings and upcoming structures have taken the home of many wildlife animals. The greatest threat to Canadian wildlife is habitat loss, affecting over 80 percent of endangered species (Canadian Points of View: Endangered Species, 2016). For a species to be

2016). Major human activities that contribute to climate change are greenhouse gases, fossil fuel and self-pollution. Greenhouse gases refers to gases such as carbon dioxide, nitrous oxide, and ozone, while fossil fuels are classified as non-renewable resources such as coal, oil, and natural gas. This ongoing issue has been increased due to population growth, more people equals a stranger impact on the environment. Developed countries have been the primary contributors to this process, through the increased consumption of fossil fuels associated with industrialization and rising economic productivity. Climate change has been most evident in the Arctic, where rising temperatures have diminished oceanic ice covers and cause permafrost thawing. In addition, Canada has also seen decreased water quality and supply, damage to vulnerable coastal ecosystems, increased frequency of forest fires, and higher rates of death from urban heat waves, from climate
It is an unquestioned fact that the climate is changing. There is abundant evidence that the world is becoming warmer and warmer. The temperature of the global land average temperature has increased by about 8.5 degrees centigrade from 1880 to 2012 (Karr, et al 406). The one or two degrees increase in temperature can cause dramatic and serious consequences to the earth as well as humans. More extreme weather occurs, such as heat waves and droughts. The Arctic Region is especially sensitive to global climate change. According to the data in recent decades, the temperature in the Arctic has increased by more than 2 degrees centigrade in the recent half century (Przybylak 316). Climate change has led to a series of environmental and ecological negative

The emission of carbon dioxide has contributed to 80% to the heating of the earth atmosphere. Carbon dioxide is produced due the burning of fossil fuels such as natural gas, coal and oil. The burning of fossil fuel is very important in our society today, because it is used for cooking, used to produce electricity, for heating, for cooling and also for transportation. The industrialization has led to the use of fossil fuel for running machines and driving cars. The building of fossil fuel contributes towards 80-90% of the carbon dioxide we find in our atmosphere today. When the ecosystems are altered and vegetation is either burned or took out, the carbon stored in them is relinquished to the atmosphere as carbon dioxide (What causes global climate change, 2005). Methane is another gas being produced in the process which all have served to increase the greenhouse effect in our atmosphere. Methane is produced from the cultivation of rice, from the burning of coal and from cattle, it has increased by 145% due to human
Overpopulation does not only affect humans and put a greater risk of getting in a vehicular wreck caused by a deer running out in the highways and interstates, but it has tremendous effect on environmental
Canada’s arctic has evidently suffered from substantial climate change, resulting in devastating impacts on all systems in the north. Many climate models indicate that these significant changes will only progress in the future. The monitoring of temperatures in the Arctic have demonstrated that, over roughly the past 50 years, there has been a warming of about 2 to 3°C as of 2009. The average temperature in the arctic has increased almost twice as fast than the rest of the world. In 2020, the projected increase is up to 4°C as well as 8°C by 2050. A numbers of studies have shown that, based on previous climate records, there has been issues of rising sea levels, alterations in sea-ice dynamics, and permafrost degradation. Though there have been multiple strategies posed and adopted, the government of Canada needs to develop an arctic strategy that is more proactive and systemic than previous actions. This strategy needs to be global in its goals for mitigation while still monitoring social, cultural, and economic aspects
Most climate scientists agree that the main cause of global climate change is the human expansion of the greenhouse effect. This is the global warming that results when the atmosphere traps heat radiating from Earth toward space (climate.nasa.gov). The main gases that contribute to the greenhouse effect include water vapor, carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons (climate.nasa.gov). Human activities are changing the natural greenhouse effect. The burning of fossil fuels like coal and oil has increased the amount of carbon dioxide in the atmosphere (climate.nasa.gov). Carbon dioxide levels have increased from 280 parts per million to 379 parts per million in the last 150 years due to human act...
For instances during a hurricane and flooding natural vegetation get destroyed, and it serves as food. By digesting this debris, they are adding uncontrollable levels of carbon dioxide and methane to the atmosphere affecting the nature of balance greenhouse gases effect. The greenhouse effect is another natural factor affecting global climate change it responsible for absorbing infrared radiation, thereby trapping and holding heat in the atmosphere at a steady temperature any increase cause increase heat in the atmosphere. Since the industrial revolution global climate change has been on the increase thou the natural factors mention above aided certain aspect of this change by contrast human beings are adding to this change as well. For instance, studies have confirmed that human beings are the main contributors of increases in the greenhouse gases effect through the burning of fossil fuels and gasoline, coal, natural gas, and other common fuels to make electricity or drive cars, they release a substantial amount of carbon dioxide into the atmosphere.
Which is creating greenhouse gases, I will focus on the activities humans do that create green house gases and overall affect climate change. There are three main ways how humans create gases, they are, the burning and use of fossil fuels, agriculture some gasses animals exhale and the last main way is the improper disposal of garbage and the excess of garbage being created. The first of those three issues i’m going to cover is the burning of fossil fuels or the use of fossil fuels. Fossil fuels are formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years. Then people extract these fossil fuels from the ground and use and sell them as energy source for us to use.
Humans and animals breathe out Carbon Dioxide, often referred to as the greenhouse gas, as a waste product. Plants take in this CO2 and use it to make food. This is called photosynthesis. During this process oxygen is released which is then breathed in by humans and animals. This procedure is repeated over and over and a natural balance is obtained. However this natural balance is disrupted by human activity. People of the world are putting more than 5.5 billion tons of CO2 into the atmosphere every year. 75% of this is caused from the burning of fossil fuels. These fuels are burnt all the time to run factories, power plants and vehicles. The main sources of CO2 emissions are electric utilities, residential buildings, industry and transportation. The other 25% is induced by the destruction of the world's forests. The reason for this is that there are less trees and plants to take in the CO2 but there is just as many, if not more, humans and animals to breathe it out.
The commonly debated “greenhouse effect” refers to “the global average temperature increase that has been observed over the last one hundred years or more” (Spencer). President Barack Obama addressed the issue in an effort to highlight its severity, "We have to all shoulder the responsibility for keeping the planet habitable, or we’re going to suffer the consequences – together” (Leader). The earth’s increasing atmospheric and oceanic temperatures result in climate changes due to cumulative amounts of carbon dioxide (CO2) in the atmosphere. As an outcome, researchers around the globe have established that the by-product of burning fossil fuels is the main culprit of the increasing temperatures. Global carbon emissions from fossil fuels have significantly increased since 1900, as shown above from a study carried out by the Carbon Dioxide Information Analysis Center.

Population has been increasing every year and the more humans and animals the more we let out carbon dioxide. Deforestation is growing too because lots are cutting plants and tree and those things give us oxygen. Mine activities are caused by humans and there's gases that stay in our world. Burning fossil fuels are caused by humans because of factories, homes, and transportations. I can prove it too because a reporter from Los Angeles Times, named Liam Dillon claimed, “California’s largest portion of greenhouse gas emissions comes from pollution generated by cars and trucks.”
The most destructive human contribution to climate change is fossil fuels combustion, which results in the release of carbon dioxide and other greenhouse gases into the atmosphere. Increased carbon dioxide, methane, nitrous oxide and halocarbons levels in the atmosphere cause an imbalance in the earth’s energy. This is because the gases alter solar radiation and thermal radiation which regulate the earth’s energy. Research indicates that anthropogenic climate change is the cause of the increased global warming over the last fifty years. 57 % of the carbon dioxide emitted is absorbed into the atmosphere while the rest is absorbed into the oceans. Carbon dioxide in the atmosphere is the most central greenhouse gas that is associated with global warming (Eby, Zickfield, Montenegro, Archer, Meissner, & Weaver,
Overpopulation is a growing problem all over the world. This is a very important environmental issue and needs to be dealt with. This environmental problem is affecting many countries around the world, but mostly the poor and impoverished countries that don’t have the resources to help deal with these issues. It also affects the environment like plants, animal life and air quality. When the population of people expands we need more natural resources from the environment, so we consume more than we can produce.
Climate changes occur in our earth's atmosphere due to a buildup of greenhouse gases. Greenhouse gases can occur naturally as well as a result of human activities. The greenhouse gases are carbon dioxide, methane, and nitrous oxide. “Carbon dioxide is released into the atmosphere when solid waste, fossil fuels, and wood are burned.” (2) The gases help to warm the surface of the Earth. Each greenhouse gas absorbs heat differently. If natural gases did not occur, the temperature of the earth would be considerably cooler. “Problems can occur when higher concentrations of greenhouse gases are present in our atmosphere because they have enhanced our earth's heat trapping capability.” (3)
