Estimates indicate that the earth can recycle about 225 billion tons of CO2 a year. This amount comes from respiration, decay and fires. Human activity adds about 7.7 billion tons a year (5.5 billion from fossil fuel use and 2.2 billion from deforestation)
An oak tree can absorb about 48 pounds of CO2 in a year.
It saves around 350kg of co2 a year
Too much !
Please spell out "CO2"
Earth's atmosphere is about 0.035% CO2. Since the atmosphere is just a thin layer of gas surrounding the earth, CO2 is a much, much smaller fraction of the earth itself.
Too much CO2 makes the Earth warm up. On Venus the atmosphere is 93% CO2 and the temperature is 400-500 degrees.
If there was no Carbon Dioxide on Earth it would be very different then what it is now. Firstly plants need CO2 for photosynthesis, without CO2 plants could not complete photosynthesis and would die of starvation (photosynthesis is a plants way of making food). Secondly CO2 is a gas that keeps the Earth's temperature at the correct level, without CO2 the Earth would be much colder and therefor unable to support life.
Very little. Carbon dioxide is ingested by plants, which require it. When we eat the plants, some of the carbon is exhaled as CO2. The Earth is essentially a closed system; the carbon that is here on Earth will remain here on Earth. Carbon dioxide is a natural part of our atmosphere, and is present in only trace amounts.

Venus' atmosphere consists mainly of Co2 (Carbon dioxide), while Earth's atmosphere is Co2 and oxygen. Co2 is much denser than oxygen, so it holds more heat from the sunlight. This trapping of heat by gases is known as the "greenhouse effect", and while we are experiencing a small amount of it on Earth, Venus has a higher concentration of Co2, making the effect MUCH more severe. The effect is also more severe because Venus is closer to the sun.
Carbon dioxide (CO2) makes up about 0.04% of Earth's atmosphere. While it is a relatively small percentage, CO2 plays a significant role in the Earth's climate system.
CO2 makes up approximately 0.03% of Earth's atmosphere
