How does carbon dioxide have an impact on the environment?

Answer 1

It holds heat and if there is enough of it, keeps oxygen breathers from living.

Answer 2

Carbon dioxide is absorbed by vegetation and converted to sugars to feed them by the process of photosynthesis. The same process releases oxygen into the atmosphere.
Most carbon dioxide in the atmosphere comes from natural sources but the amount added by mankind is disturbing the natural balance. Carbon dioxide is believed to be building up in the atmosphere. It lets sunlight through to the earth which then gets warm and radiates its heat back out into space .... but the carbon dioxide is working like a greenhouse to keep the heat IN so many scientists believe this will cause global warming (a continual temperature rise as opposed to normal cycles in the earth's temperature). Methane (as given off in paddy fields and from the digestive system of cattle) is an even stronger greenhouse gas.
Part of the problem is that less carbon dioxide is being absorbed by huge trees in the tropical rain forests because large areas have been cleared for farming.
Carbon dioxide in the air combines with rain water to form a weak acid, carbonic acid, which can attack stone buildings and can make lakes and rivers slightly more acidic which does not suit every life form of plant. It also falls as so called 'acid rain' which contributes to the death of forests. That means the forests are no longer there to absorb carbon dioxide in the future and it also means the timber is not available as raw material to make houses or furniture etc.

Answer 3

Hey try this as an answer the environmentalists don't like.

More CO2 increases the rate of growth of plants. This could allow crops to mature earlier (quicker) giving time for another crop cycle and help feed the world etc

Other answers are also correct, but don't assume these issues don't have a positive side as well as a bad side.

Dare to be different

Answer 4

Carbon dioxide is somewhat regulated by one of the most common minerals on the planet, calcite. Calcite pulls in CO2 to grow. Several sea creatures use calcite in their shells.

Answer 5

it causes the increased greenhouse effect as it absorbs and holds more heat.
It also combines with water vapour to form a weak carbonic acid which does very little damage to limestone.

Answer 6

co2 thickens the layer that distribute the sun rays that make the earth warm.
