The causes of farmland degradation

The pie chart presents four main reasons leading agricultural land to low yield. And the table illustrates a statistics about the situations of lands in three countries, which is affected by the mentioned causes.

The pie chart shows that over-grazing is the dominant reason causing land degradation, which takes 35%. Deforestation is close behind with 30%, and the influence from over-cultivation is listed 3rd with 28%. Other factors only account for 7%.

In the 1990s, the degradation of land in Europe was most serious, with 23% of total land degraded throughout the period. Oceania came next with 13% and North American ranked 3rd with 5% in total. Deforestation made up the largest percentage of 9.8% in Europe, followed by over-cultivation (7.7%) and over-grazing (5.5%). In contrast, only 0.2% of degraded land was due to deforestation in North America, while over-cultivation and over-grazing took larger proportions of 3.3% and 1.5% respectively. In Oceania, a lmost all land degradation was caused by over-grazing (11.3%). However, over-cultivation never appeared in Oceania over these years.

As can be seen, over-grazing, over-cultivation and deforestation lead to/result in more than 90% of degraded land, which have different influences on the three mentioned countries.

The ages of the populations

The four pie charts present a statistics of residents' ages in Yemen and Italy in the year 2000 and a relevant prediction for the year 2050.

In the first two charts of Yemen, the percentage of people aged from 15 to 59 is projected to rise from 46.3% to 57.3% between the year 2000 and 2050. While the proportion of people under 14 years old is foreseen to decline by 12.1% from 50.1% during the 50 years. There would will be a slight increase for the ratio of people aged over 60, which is from 3.6% to 5.7% from the year 2000 to 2050 in expectation.

In the other two charts of Italy, approximately two-thirds people in Italy are were 15-19 years old in the year 2000, which is projected to decrease to less than a half after the following 50 years. The group of Italian over 60 years old takes 24.1% and 42.3% in the year 2000 and 2050 respectively. In the year 2000, 14.3% Italian are were under 14 years old, however, this data is estimated to fall to 11.5% by the year 2050.

As can be seen, the group aged 15-59 is expected to take the first place in both Yemen and Italy in the year 2050. On the other hand, the people over 60 years old in Yemen are much more than Italian in of the same age group, not only in the year 2000, but also 50 years later.

Women Should Be Allowed to Join The Army

With the gender gap in many different fields closing, a part of people consider that governments should allow women to join national military departments, such as the army, the navy and the air force. From my perspective, it is necessary that countries open this policy for the females, although there are some difficulties to put with puting this idea into practice.

Doubtlessly, almost all countries are engaging on in gender equality. Opening military positions for female citizens is would be/could possibly be one of the most important achievements. From my understanding, legislating to permit female soldiers does not only mean to enhance the employment of this group but also show the development of democracy. Further more, women need the opportunities of working in troops the forces to realize individual ambition, to perform civic duties and to show genuine patriotism. To some extent, military departments are one of the most ideal places to make contributions for a country.

Nevertheless, some sexual gender features of female soldiers would be could be/is likely to be barriers for performing as well as male ones, especially the relatively weak average physical strength and psychological quality. As a result, nations have to spend a longer period and pay more funds to foster train them. In addition, there is another social responsibility of for the majority of women that they need to get pregnant and bring up a the next generation. While, sometimes, the intense working environment in troops the forces has might have a negative effect on pregnancy. Besides, children in families that in which/where both parents join the army would suffer from loneliness and insecurity. It means that without parental protection, these children are easier to be hurt and bullied physically and mentally.

All in all, allowing women to join the army is a necessary and meaningful policy, which helps to ensure the female’s females' legitimate rights. However, governments should be careful about setting corresponding regulations to make sure the normal life of female soldiers’ families. From above, I agree with allowing women to join in the army.
