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: Global Demand For Energy and Global Warming

Image
Global  demand  for  energy is the need of energy to power building, industry, transportation and other socioeconomic factors.   City by night (Pixels Art, 2021) Global demand for  energy is increasing due to industrial activity and advances in both developing and developed countries. Fossil fuel energy sources –such as coal, natural gas, and oil– are used to meet energy needs for much of the world. But the combustion of fossil fuels has increased the amount of CO2 in the atmosphere by more than a third since the Industrial Revolution. The rapid rise in greenhouse gases is a problem because it’s changing the climate faster than majority living world can adapt to. Moreover, burning fossil fuels emit high amounts of particulate matter and toxic gases that are highly harmful to health.  Polar bear struggled to find food due to ice melting. (The times, 2017).  Every year, an estimated 40,000 children die before their fifth birthday because ...

The problems of Earth: Plastic pollution

Image
Plastic pollution is the accumulation in the environment of synthetic plastic products.   Plastic polluted “paradisiac” beach in Tulum, Mexico (Maria Serra, 2018) Plastic pollution has become one of the most pressing environmental issues: the accumulation of plastic in the ecosystem creates problems for wildlife and their habitats as well as for human populations. When the first plastic was produced in 1860, little they knew that the material would be so harmful. From that first object –a billiard ball– many modifications have been made: now plastics contain additives making them stronger, more flexible and durable.  Nowadays, 500 million metric tones of plastic are produced every year –90% more than 40 years ago– and it is projected to triple by 2050. 12 million tons of plastic waste –the equivalent of 800 Eiffel Towers– escape to the oceans annually. Every second, 200Kg of plastic is dumped into the sea. 80% of the plastic trash in the oceans –Earth’s last sink– flow...
