The dangers of fossil fuels

During the combustion process of fossil fuels, sulfur dioxide, carbon monoxide, smoke, radioactive dust, nitrogen oxides, carbon dioxide, etc. are released. These substances will directly harm humans and animals, cause cancer in the body, cause radiation damage to organisms, produce acid rain, and form a greenhouse effect.

The most typical environmental impact of the mining process is coal mining, including damage to land, damage to villages and impact on water resources.

Demonstration of ability

Do you have any reasonable suggestions to improve the greenhouse effect caused by large amounts of fossil fuels?

Reduce the burning of fossil fuels

Develop and utilize new non-polluting energy sources

Plant more trees

Ways to solve the energy crisis:

Find ways to extend the use time of existing energy: improve energy conversion rate; develop and use energy-saving products.

Develop and use new energy sources.

Nuclear energy: Since the fuel of nuclear power is nuclear fuel, the advantage compared to coal or oil is that there is no air pollution, no oil leakage and other problems. Its only drawback is the presence of radioactive contamination.

Geothermal energy: Research shows that the reserves of geothermal energy are equivalent to 170 million times the thermal energy of the earth's coal reserves, which can be consumed by humans for tens of billions of years. It is truly inexhaustible and will be prioritized for utilization and development in the future.

solar energy

The surface temperature of the sun is as high as 6000°C, and nuclear reactions are constantly taking place inside the sun, and it emits huge energy into the universe in the form of radiation. It is estimated that every three days the sun radiates as much energy to the earth as the energy of all the fossil fuels on earth combined.

There are three ways for humans to utilize solar energy: converting light energy into thermal energy, converting light energy into electrical energy, and converting light energy into chemical energy.
