The Problems of Earth: Demand for raw materials

Image
The demand for raw materials is the need of basic materials or substances that are used to produce goods.   Example of metallic raw materials (KWG industries, 2021) Over the coming years, the situation on the raw materials markets is likely to remain tense as large countries such as China, India and Brazil press ahead with infrastructural development and industrialization. As part of this trend, the industrialized countries are losing influence, and weaker developing countries are becoming even more marginalized. City of Ahmedabad, the 5th largest city in India and the 3rd fastest growing city in the world (scoopwhoop, 2014) Resource conflicts are erupting and highly developed countries are determined to safeguard their access to raw materials. As an example, the European Union is almost entirely reliant on imports. The situation is specially critical in relation to certain strategic metals which will continue to be essential for key growth technologies in the foreseeable f...

The problems of Earth: Deforestation

Image
Deforestation is the massive destruction of trees. It is the clearing of forests by humans. (Aerial image of Brazilian Amazon Rainforest cleared. Skynews 2017)   In 2010, scientists predicted that in 100 years ’ time the rainforests would disappear completely if human being kept cutting down the trees. In 2020, scientists predict that by 2030 the Amazon rainforest will be a S avannah. The Amazon rainforest is the largest remaining block of humid tropical forest. We are in 2020. We only have 10 years left.   Rainforest ecosystems have a crucial role in the water cycle on Earth. Moreover, they hold a huge amount of biodiversity: 80% of the World’s animals and plants inhabit the forests and rainforests.   (Californian forest. Take Part.)   But… What are the main causes of deforestation?   The first one is agriculture and grazing. Farmers cut down the trees in order to gain more farmlands. Secondly, the wood/paper industry. Thirdly, humans remove trees for construc...
