Life Cycle Analysis Big Mac

Water is one of the most precious resources, which support the life of almost everything in the world. Indeed, the world is covered by 75% water, but most of this water is not suitable for human consumption or use. On the same note, the world has been increasing its consumption of water due to the increasing population, leading to increased demands. The increased water consumption, which has been a result of high population, is worrying because the matter may lead to massive water shortages in the future.

In a dry year, the “groundwater contributes up to 46 percent (or more) of the statewide annual supply”

4. Using recycled fibers from paper has several advantages, including lower cost to recycle paper than produce pulp.

2. (a) One general effect of overuse of an environmental resource is cutting down trees.

Which of the following is not an environmental impact of conventional agriculture expressed in your text?

Water is all around us. This substance is of high importance to every living thing which is on planet earth. As much as we consider water to be life and the most important substance, still we don’t seem to appreciate it very much, as it is being wasted in such great amounts. Everyone believes that water will always be around but not taking into account that the majority of the water on planet earth are not for human consumption. Human beings can only survive on consuming fresh water. The percentage of

$42,953, was 63.6 gallons per person. We can conclude that the more money one makes, the more water he consumes and the less

The water supply now and in the future affects the population in many ways. According to “Water in 2050”, the water supply is the determining factor of how large the population may grow. In some areas lack of

Population, household size, and growth will influence all affect how on much water is used. We

Water usage for agriculture in Ontario is exceeded by two other sectors but, does play a large part and quite important as it generates a lot of economic revenue for the citizens. In Ontario, the Canadian Government requires all farmers who will be withdrawing more than 50,000 L of water to obtain the “Permit to Take Water”. This allows for the government to monitor how much water is being allotted to the agricultural sector. There are several issues faced by the government when trying to track water usage rates in Ontario. Agricultural water use in Ontario is distributed amongst 60,000 farms (figure 1) mostly in Southern, Ontario (Loë, 2005). The allocation of water in Ontario depends on accurate information from the sources of water, users

Most of water consumed in China is not rationally used. The cause which intensifies the water shortage in China is water inefficient use. For instance, 65%-70% of Chinese water

And the third example is the population. If the population increase, people need more places to live. They need more soil to grow the food. This will make the soil loose and the water may flood it away. And the other activities of human will pollute the environment. However, the bad environment will affect the human activities.

According to water footprint studies, three classes of water use exists, namely, blue water which refers to the volume of surface and groundwater consumed in the manufacture of a product, green water which refers to the volume of consumption of rainwater excluding any runoffs and grey water is polluted water and by definition is the amount of freshwater needed to assimilate the load of pollutants given natural background concentrations and existing ambient water quality standards (Hoekstra et al 2011). The understanding of water footprint will eventually lead behavioral changes which will in turn ensure sustainable water use.

The Figure 2 presents the quantity of water is consumed by international students every day. In general, these students drank less water in Australia than they did in their own countries. There were 10% and 24% of the sample drank more than 2 liters per day when they were in Australia and their own countries respectively. However, there were
