Yes, anemia refers to a low number of erythrocytes in the blood, and therefore less oxygen can be transported at a given time.
Carbon monoxide
An increase in the amount of organic matter in an aquatic system will reduce oxygen levels because if more organic matter is introduced the population of decomposing bacteria will increase and they will use up more oxygen for respiration (by which they decompose matter) than that which is being produced, thereby reducing oxygen levels.
you can reduce it by stuff
Carbon monoxide a waste product found in cigarette smoke is more readily absorbed by the red blood cells than oxygen. This reduces the ability of the red blood cells in transporting oxygen around the body.
The heart rate slows to reduce the amount of oxygen used by the heart, and the amount available for use by muscles for the penguin so that it can stay longer underwater
by fixing a catalytic converter in an exhaust system You should find the cause of the high reading. Its almost like asking if you want to cure the problem or just hide it. And high CO indicates a rich fuel condition hence extra expense in operating the car. At $3-$4 a gallon, fuel economy is important.
to reduce pollution
Smoking can reduce the amount of oxygen the baby recieves.
Plants reduce the amount of carbon dioxide in the air and increase the amount of oxygen.
By smoking you reduce the amount of oxygen carried in the bloodstream because one of the gases generated by the burning of the tobacco is carbon monoxide. This gas combines with the haemoglobin in the red blood cells in the same way that oxygen does. But when this happens the oxygen-carrying power is obviously reduced. This is why carbon monoxide is a poison.

A gentle blow, which increases the flow of oxygen around the flame will make it bigger. A strong blow which will reduce the air pressure and so reduce the amount of oxygen will make the flame smaller.
They agreed to gradually reduce the amount of nuclear weapons held by each country - the did not, however, agree to reduce the number of warheads carried by each missile !

Carbon monoxide a waste product found in cigarette smoke is more readily absorbed by the red blood cells than oxygen. This reduces the ability of the red blood cells in transporting oxygen around the body.
The inhaled smoke takes up space in the lungs which should filled with air. This in turn reduces the amount of oxygen in the blood stream because of space now filled by poisonous gases taken from the smoke.
Oxygen moves purely by diffusion. ANY material blocking that diffusion will reduce the rate of diffusion.
