Living Environmentally Sustainable

Week 5







“The greatest threats to any species are loss or degradation of habitat, harmful invasive species, human population growth, pollution, climate change and overexploitation” (Miller and Spoolman,2009, p. 94).






Discuss three ways in which you could apply this concept to make your lifestyle more environmentally sustainable. (Miller and Spoolman,2009, p. 112).”





The impact of human activity on the earth’s biodiversity has lead many valuable species to extinction. The earth’s natural capital is vital to human survival as they provide food, medicines and essential nutrients. Everyday humans can slightly modify their lifestyle to live more environmentally sustainable.



Packaged products in supermarkets such as muesli bars and instant meals consume non renewable resources that pollute the atmosphere and increase landfill. To save on this unnecessary packaging, a healthier and environmentally friendly option is to buy more loose foods including fruit and vegetables. At home the food can be placed into reusable containers rather than using plastic bags that just get thrown away. While at the supermarket, remember to buy a green ‘eco friendly’ bag to re use instead of plastic. Every year on ‘Clean up Australia Day’ nearly half a million plastic bags are collected! (Department of Environment, Water, Heritage, and the Arts, 2009).






Riding a bicycle and walking to work or school is a much healthier option than driving a car. By using the car less saves money plus reduces the pollution and carbon emissions in the atmosphere causing global warming. If riding or walking is not convenient, there are other options including car pooling, public transport or even purchasing a fuel efficient car (Department of Environment, Water, Heritage, and the Arts, 2009).






A simple way to live more environmentally sustainable by saving energy in the house is to simply turn off lights, televisions, fans and heaters when they are not being used. Replacing regular household lights with energy efficient lighting such as LED and CFL bulbs can drastically save energy and reduce electricity bills. Not only are they energy efficient but they are long lasting, durable and mercury free (Earth Easy, 2010).






It is hard to think why people on earth are not living more environmentally sustainably as the options above not only benefit our health but also save money. The best way to remember how to live environmentally sustainably is to‘re use, reduce, recycle and refuse’.

“Some people believe that our most important goal should be to sharply reduce the rate of population growth in developing countries where 97% of the world’s population growth is expected to take place. Others argue that the most serious environmental problems stem from high levels of resource consumption per person in developed countries, which use 88% of the world’s resources and have much larger ecological footprints per person than do developing countries.



What is your view on this issue? Explain your response” (Miller and Spoolman,2009, p. 93).


Population growth in developing countries and high levels of resource consumption in developed countries are both serious environmental problems. People in developing countries are focused on having enough food and water for survival rather than the impact of population growth. Is it fair that half the world’s population are living in extreme poverty surviving on less than $2 a day (Miller & Spoolman, 2009) when there are people spending billions of dollars on goods and services, depleting the worlds non renewable resources and increasing ecological footprints only to make their lives more luxurious and efficient (Shah, 2010)?


There are 1 billion children in this world in poverty (Shah, 2010), lacking food, water, shelter, health care, sanitation and education. Reducing population growth in developing countries will help condense poverty, which is a major cause of environmental problems. Each year in developing countries 52 million pregnancies are unwanted. (Miller & Spoolman, 2009). To ensure every baby is wanted it is vital to provide family planning services to control these unpleasant figures. In China sons are the preferred child as they are brought up to work and support their parents, this has lead to an enormous rate of baby girls abandoned or left in orphanages (YouTube, 2009). Not only will poverty decrease if population growth was controlled but the depletion of the earth’s forests, grasslands, wildlife and fisheries will be maintained as pressure for land, food and water will decrease.


Population growth can cause environmental impact but no more than what is spent on modern technology, new cars and cosmetics every year in developed countries. The need for these products is putting strain on the earth’s natural capital and polluting the earth with gases and wastes (Miller & Spoolman, 2009). The use of oil for plastics, paint, cleaning fluids and vehicle transportation are causing pollution in the air and water as well as releasing greenhouse gases into the atmosphere when burnt. The United States of America use 24% of the world’s oil production and only produce 9% (Miller & Spoolman, 2009). At this rate the world will need to find a substitute within 50 years as it is a non renewable resource.

“We abuse land because we regard it as a commodity belonging to us. When we see land as a community to which we belong, we may begin to use it with love and respect.” – Aldo Leopard (Miller & Spoolman, 2009, p.16)

Providing universal education, family planning and implementing population policies will benefit the world however it is up to humans to rethink the impact of resource consumption to live in an environmentally sustainable society.
