Answer: The biosphere is under stressed and the contributing factor is the overuse of resources that are not renewable due to significant growth in population, consumption of resources and technology. 3. Define sustainability. What do scientists predict will happen in Earth’s future if we do not increase our sustainability practices? Answer: Sustainability is the quality of not being harmful to not environment or depleting natural resources, and thereby supporting long-term ecological balance (American Online Dictionary).
What are the impacts of overpopulation and what can be done about it? “Population growth is the primary source of environmental damage” (Jacques Cousteau). The most of all worlds problems are due to overpopulation. The Humanity is condemned if the situation doesn’t change. The increased birth rate, increased longevity, reduced infant mortality, lack of education, the cultural influences and the inefficacity of the countries to prevent overpopulation effect are the causes of overpopulation.
Martin LaMonica mentions that “ultimately the company’s rationale for “going green” was purely economic, according to former CEO Lee Scott” (LaMonica, 2010). Walmart has started a number of initiatives including reducing waste in packaging, creating a sustainability index of its suppliers, using solar panels on newer built stores, and using out of date food products as compost. “In 2005, when then-CEO Lee Scott announced the three key pillars of our commitment to sustainability—to be supplied 100 percent by renewable energy, to create zero waste, and to sell products that sustain people and the environment—it caught the world’s attention” as said in Walmart world ("Sustainability 360", 2010, p. 33). Sustainability is not an added expense that upper management has figured out. By doing so means increased efficiency being able to add more containers per truck, less fuel used to transport
This paper will explorer and analyze the environmental practices of Wal-Mart in an effort to at least in part determine how far they have come to reaching those initial goals. Keywords: environment, environmental strategy, environmental initiatives, sustainability, greenhouse emissions, energy, An Analysis of Wal-Mart’s Environmental Strategy: The Pursuit of Becoming a Sustainable Company According to the article, Wal-Mart’s Environmental Strategy, the company never really had a leadership position when it came to environmental initiatives. Instead, Wal-Mart was encouraging consumption at alarming rates and causing massive amounts of waste and run-offs due to construction (Nandagopal, 2009). In addition to environmental criticism, Wal-Mart’s reputation was taking a beating with regards to labor practices and its relationship with the society/community. They had the persona of not being very friendly, despite its smiley face mascot.
There are many different reasons why extinction happens, some of these cause are natural but the majority of them are due to human activity such as deforestation and an increased amount of fossil fuels being used which then leads to global warming. Extinction has increased 100,000 times more than before humans were on earth. There currently is a mass extinction of species since the extinction of the dinosaurs 65 million years ago, some of the main causes of this are habitat destruction, invasive animals, population growth, pollution and over exploitation. Biodiversity is the variety of plants and animal life in the world or in a particular habitat which are affected negatively due to some activities that humans are causing such as climate change. My first piece of evidence in favour of human activity leading to extinction is ‘humans are driving animals to extinction faster than they can evolve ‘written by Juliette Jowit, (on Sunday the 7th of March 2010), the guardian newspaper, 15/01/15.
Human Population: Mitigation and Solutions University of Phoenix SCI 275 November 04, 2012 Human Population: Mitigation and Solutions The human population is at an all-time high. The growth of the human population is one of the challenging and important issues we face (Lima & Berryman, 2011). With the growth of our human population we face problems like economical, ecological and geographical. We as humans are doing a job on the world. Like I said before we are over working our environment, and putting a strain on our natural resource.
This means that, there is no need to buy or import fertilizers because it would simply use organic/natural manure which then will lead to more work load that can be done youths who has no job. "One of my biggest mistakes was using fertilizers and not having any knowledge of what it does to the soil, nor was I aware of the impact of the overuse of weedicide," (Mr Narayan,2012), a farmer with 25 years of experience. Hence, organic farming gets good yields and earn a sustainable income. Another positive economical contribution is getting the farm certified. Certified organic items usually sell for higher prices than standard items and it provides market opportunities for Pacific island farmers and their families.
But because of the global warming, many areas of the world are experiencing increased hurricanes, floods and other unusual weather. Speak about floods, the central Europe was experienced the worst flood that it hasn't seen in at least 70 years. It obviously that global warming is effect the weather. But in fact the effect of the global warming is not just this. The third problem of the global warming is the changes of the biological systems.
Current projections estimate complete depletion within the next 80 years. What's the point? Where did we go wrong? 2nd Main Point As long as we continue to burn fossil fuels, it will continue damaging the environment. Add to that the import and export of our fuel and then we see how it impacts us financially.
Natural environments are changed by people. It impacts people living in negative ways. Firstly, global warming is the most important issue. Global warming has affected so much in temperature that increasing in temperature. Next, it is becoming increasingly difficult to ignore the lack of energy; people tend to use more fossil energies which are non-renewable energy.
