Ear cropping surgery requires precision and skill in order for the ears to stand up and appear as intended after healing. This procedure must be performed by a veterinarian and is best done by one with experience in ear cropping. Dogs must be under general anesthesia for ear cropping surgery. Ear cropping is generally performed on puppies between the age of eight to twelve weeks. After surgery, the ears are bandaged and propped up so they heal in an erect position.
Carbon dioxide is the most commonly cited greenhouse gas because of  its natural abundance in the atmosphere. It constitutes 80% of the  non-condensing greenhouse gases.

It should be noted that methane, by itself, when released into the atmosphere, is a potent greenhouse gas. It captures heat [70 times] better and thus, by weight, is 70 times as dangerous as carbon dioxide. This is why itâs so important to flare methane to ensure that it is completely combusted into carbon dioxide.ntroduction to Methane. What we call natural gas is mostly the chemical compound methane (95% or more; the rest is ethane or longer carbon chains). Methane, which comes out of the ground as a gas, is produced when microorganisms known as methanogens feed on organic matter in environments with little or no oxygen.
