5. We need to conserve fossil fuels an
o conserve fossil fuels and at the same time have to look for alternative
sources of energy. Justify the statement.
Answers
Answer:
The conservation of fuel through more energy-efficient technologies and practices may help extend the current reserves of petroleum, coal and gas for a few more years. Unless world economies begin to rely more on renewable resources, though, the supply will surely run out. However, there is a more important reason to conserve fossil fuels, and that's to help heal the environment.
Burning petroleum, coal and natural gas fills the air with harmful pollutants, including nitrogen oxides, sulfur dioxide, carbon dioxide, ozone and a host of hydrocarbons. Besides creating smog and respiratory diseases, these pollutants – particularly carbon dioxide – collect in the atmosphere and prevent the Earth's heat from escaping into space. As a result, scientists predict the Earth's temperature could increase by as much as 4 degrees Celsius by the end of the century. Besides this disastrous outcome, carbon dioxide also acidifies the oceans, killing sea creatures and reducing the ability of ocean water to absorb this harmful gas.
The conservation of fuel slows both the rate of atmospheric warming and ocean acidification, hopefully giving the Earth time to heal itself. Without this respite, the Earth may reach a tipping point beyond which that healing is impossible, and it may become uninhabitable. That is probably the most compelling reason to conserve fossil fuels.
