Answer:
D. Pollution
Explanation:
The pollution is a consequence of the growing economy in advancing nations. The economy is growing, and transforming rapidly in the last two decades. Some characteristics of this change are: technological innovations and modernization, competition in the global market, etc. However, the pollution still a severe problem in developing countries. This is because, these countries doesn´t have a substantial economic growth, therefore cannot afford to focus on environmental problems.
Developing countries need to decide between keeping competitive prices to obtain and sustain economic growth while the poverty decrease. This decisions usually lead to environmental pollution. For example In sub-Saharan Africa, depends mainly on natural resources. They over exploits of natural resources such as coal, oil and gas, gold, copper. This cause pollution in air, water and land, and it can impact the climate change.
They should care more about pollution, because it also affects the health, sometimes leads to death of the population. Is important to mention that per year millions of people can be affected.
Answer:
Coal is made by heating of woody plant material, and oil is made by heating of algae.
Explanation:
The coal and the oil are both fossil fuels. They have both been very important for the development that the humans have experienced since the Industrial Revolution as they were what provided the energy needed for this process, and they still do.
The coal is a fossil fuel that has formed from woody material, mostly from the Carboniferous forests. Once these forests collapsed, they were quickly covered with water, mud, and sediments. Over time they were covered with even more sediments, so they were getting deeper into the crust. As they were getting deeper into the crust this material was exposed to higher temperatures and pressures, leading to the formation of the coal over the course of millions of years.
The oil is a fossil fuel that has formed from the remains of the marine life, mostly algae. As the algae and the other marine organisms have been dying out, they have fallen on the bottom of the oceans, quickly being covered with the soft sediments. As more and more sediments have been placed on top of them, they too were getting deeper into the crust, so they were also exposed to higher temperatures and pressures, eventually leading to the formation of the oil over the course of millions of years.
