Forest fires

Forest fires, which are tending to increase, have become a major problem in certain countries. This problem is caused by many reasons which can be divided into two main groups; natural causes and human intervention. The existance of forests are very important not only for people but also for all living things on Earth. Hence, setting fire to the forests has bad effects on them, for instance, environmental damage, increasing financial costs, health risks and climate change. Under conditions like this, measures should be taken seriously and appropriately in order to deal with this problem, action or activity humans and forests.

Concerning the causes of bushfires, both natural causes and the intervention of humans can be broken down into specific way; three major natural causes and four major causes of human intervention. Three major natural causes are long hot summers a dry climate in the forest areas and lava – flaw or hot clouds from volcanic eruptions. These three major causes help spontaneous combustion to happen in the forest areas and in the end it causes bushfires. Besides that, deliberate actions from humans such as clearing of land opening up areas for agriculture and throwing cigarette butts carelessly or forgeting to put out campfires also lead to forest fires. However, the most unforgivable human action which causes forest fires is an act of vandalism commited on purpose by some individuals who do that just to have fun.

In response to this problem, either preventive or curative measures should be implemented appropriately, both for humans and forests. Measures for humans can be undertaken through imposing penalties, enforcing the law and strengthening regulations. Additionally, actions for forests be making artificial rain with helicopters, hiring fire-fighters and replanting and maintaining threes. By preserving the forests in these ways, people can live in a healthy environment. 

To conclude, both natural causes and human intervention can cause the extreme bushfires which have many negative impacts on for all living things on earth. This problem can be solved through either preventive or curative measures which can bring back a healthy life and environment for a better future. (Rp.54.121) RP

manufacturing tea

The picture depicts the two processes for manufacturing black tea.  The traditional way is used for making loose tea and the modern process is ideal for teabags.

When collecting tea, the tea picker picks only the two top leaves and the bud of each plant to ensure a high quality tea.  Then, the tea leaves go through wihering, where leaves are spread out and air is passed through them to remove up to 60 per cent of their moisture.

After that, the leaves are ready for rolling or cutting.  Factories use traditional methods of rolling and crushing or faster modern methods of cutting, tearing and curling to make teabags.  In both processes, natural enzymes are produced from the leaves.  The next step is oxidation, where the enzymes from the leaves mix with air.  This changes the colour of the leaves from green to copper and creates a nice flovour and aroma.  Finally, the leaves are fired and dried.  By this stage, little moisture remains in the tea - just three percent (173 words)

consumption of energy in usa

The graph shows energy consumption in the USA from 1980 to 2012 and projected consumption to 2030.

Petrol and oil are the dominant fuel sources throught this period, with 35 quadrillion (35q) units used in 1980, rising to 42q in 2012. Despite some initial fluctation, from 1995 there was a steady increase. This is expected to continue, reaching 47q in 2012.

Consumption of energy derived from natural gas and coal is similar over the period. From 20q and 15q respectively in 1980, gas showed an initial fall and coal a gradual increase,  with the two fuel equal between 1985 and 1990. Consumption has fluctuated since 1990 but both now provide 2q.  Coal is predicted to increase steadily to 31q in 2030, whereas after 2014, gas will remain stable at 25q.

In 1980, energy from nuclear, hydro and solar/wind power was equal at only 4q.  Nuclear has risen nby 3q, and solar/wind by 2. After slight increase, hydropower has fallen back to the 1980 figure.  It is expected to maintain this level until 2030, while the others should rise slightly after 2025.

Overall, the US will continue to rely on fossil fuels with sustainable and nuclear energy sources remaining relayively insignificant.

Modes of transport for goods in UK

The graph below shows the quantities of goods transported in the UK between 1974 and 2002 by four different modes of transport. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

Summarize the information by selecting and reporting the main features, and make comparisons where relevant.

The line graph depicts the amount of goods carried by four types of transport in Great Britain from 1974 to 2002.  Three modes of transport, namely road, water and pipeline, showed an increase.  Rail, however, experienced a decrease for most of the time period, only picking up toward the end to finish at just above its starting position.  Road was the most important carrier, followed by water, then rail, and pipeline in last place.

In 1974, road transport accounted for about 70 million ton.  Its share then gradually increased until around 1995 when it stood at just under 80 million tons.  It then rose sharply to finally finish at a little below 100 million ton in 2002.

Water started at a bit below 40 million ton in 1974.  Then in 1978, it climbed steeply until about 1981, to just under 80 million tons.  it then rose sharply to finally finish at a little below 100 million tons in 2002.

Rail, on the other hand, after starting at 40 million tons in 1974, mostly declined until about 1995, by which time it has descended to a little below 30 million tons. It then changed course and went through a period of steady increase, regaining its original level to finish at just above 40 million tons by 2002. 

Pipeline transport was initially not a popular choice, standing at about 5 million tons in 1974, but then having three phases of relatively gentle increase, punctuated by two briefer spells of sharper increase. MH
