why is the need of for conservation of fossil fuels felt more today than a few hundred year ago
Answers
Answer:
- It is going to be exhausted
- it will be going to reduces.
- it will be very costly.
- it is very important to start the machinery.
Explanation:
Despite what you might have heard, fossil fuels don't come from decayed dinosaurs, although dinosaurs were roaming the Earth while they were forming. The main source of coal is decomposed plant matter, and oil comes from decayed plankton, a microscopic sea creature. Natural gas is also a by-product of decomposed plants and micro-organisms.
Even though the use of fossil fuels is increasing in many countries, coal, oil and gas are still abundant in the Earth's crust. Nevertheless, there is a growing awareness of the importance of the conservation of fuel sources among environmentalists and economic policy makers. This is true for two reasons: The supply of fossil fuels is finite, and the pollution from burning them is bad for the environment
The economic importance of fossil fuels is well established. The systems for extracting and transporting them have already been developed, and the fossil fuel industry employs millions of workers around the world. The economies of most countries depend on it. Switching from fossil fuels to renewable energy sources is somewhat like changing the direction of a ocean liner, taking time and a large input of extra energy. It's much easier to keep the boat sailing on the same course.
On the minus side, fossil fuels are dirty. Burning them creates atmospheric pollutants, and scientists are in virtually unanimous agreement that one of the primary pollutants, carbon dioxide, is responsible for the climate change trend that is producing increasingly erratic weather patterns. Another drawback is that the supply of fossil fuels may seem unlimited, but it isn't. One petroleum executive estimated in 2006 that there was enough coal in the Earth's crust to last about 164 years, enough natural gas to last 70 years and only enough oil reserves for 40 years. At that rate, a person in their teens in 2018 is likely to live to see the day when oil and natural gas reserves run out.
