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. Exp â¦ erts believe that the removal  of CO2 will cool the Earth by 30 degrees Celsius.arbon dioxide is the most commonly cited greenhouse gas because of  its natural abundance in the atmosphere.

Methane is the primary component of natural gas, a common fuel source. Why are we concerned about it? If methane is allowed to leak into the air before being usedâfrom a leaky pipe, for instanceâit absorbs the sunâs heat, warming the atmosphere. For this reason, itâs considered a greenhouse gas, like carbon dioxide. Is it as important to address as carbon emissions? While methane doesnât linger as long in the atmosphere as carbon dioxide, it is initially far more devastating to the climate because of how effectively it absorbs heat. In the first two decades after its release, methane is 84 times more potent than carbon dioxide.
