    HArvesting natural gas is still cleaner than coal and oil, but it still contributes a large amount of carbon dioxide to greenhouse gases. Also natural gas is mostly methane which is way more dangerous for greenhouse warming than carbon dioxide. Extraction is also one of the disadvantages of natural gas because of the creation of cavities in the ground. The pressure exerted by the gas helps support the layers of soil above the gas field. When the gas is extracted, the soil pressure increases and cavities are created in the ground. These cavities can sometimes cause the ground to sink. While extraction is an issue, another one is that the gas is toxic.

    • Even though it is cleaner than coal and oil, it still contributes a large amount of carbon dioxide to greenhouse gases.
    • By itself natural gas is mostly methane, which is 21 times more dangerous for greenhouse warming than carbon dioxide so any leakage of the gas (from animals, landfills, melting tundra, etc) contributes strongly to greenhouse emissions.
    • If your house is not properly insulated it can be very expensive.
    • Some electrical appliances require high voltage which is dangerous and costly to install.
    • It can leak, potentially causing an explosion.

    Extracting natural gas does NOT create cavities in the ground. Gas, oil, and water are present beneath the earth in the pore spaces of solid rock – not in giant caves and openings. Gas does NOT support the layers of rock – the rocks are plenty strong enough on their own, and the presence or absence of gas or oil is completely irrelevant (with some exceptionally rare exceptions). 

    Also, methane is not toxic. It can displace oxygen, resulting in suffocation, but itself is not toxic. Some naturally occurring gases, such as hydrogen sulfide, are indeed toxic.
