The bar chart describes the three factors causing harm to the land in Africa, Asia, Australia and Europe.
Overall, it is clear that Asia experienced the most land degradation, mainly due to tree-cutting, while breeding was the biggest cause in the other regions. Farming was generally the least significant factor causing land damage, except in Asia.
As can be seen from the chart, land used for breeding in Africa is 500 million hectares, compared to just 100 million hectares in Asia. Although the amount of land damage caused by breeding in Africa is higher than in Asia, both Asia’s tree-cutting land and farming land is more than the figures for Africa. The tree-cutting area in Asia is 450 million hectares, which is over 50 million more than Africa. Additionally, with over 400 million hectares, the amount of Asia’s farming land is also higher than Africa, with 300 million hectares.
Looking at the chart in more detail, there are nearly 300 million hectares of breeding land in Australia, as opposed to around 150 million hectares in Europe.In addition, the amount of land degradation caused by tree-cutting in Australia is approximately equal to that in Europe, at around 100 million hectares. However, land used for farming in Australia is 50 million hectares lower than in Europe, with 80 million hectares.
