Carbon dioxide is a gas that we cannot see or smell which is produced by many things such as when humans breathe or when factories create things. A little bit of CO2 can be good for plants, but too much can be bad for the environment because it traps heat in the air which can make the Earth too hot.
Carbon dioxide removal is a way to remove CO2 from the air to help keep our planet healthy. There are different ways to do this such as using filters, machines, or natural processes. One example of a natural process is how trees can absorb CO2 and turn it into oxygen.
However, it is difficult and expensive to remove CO2 from the air, so we also need to work on ways to reduce the amount of CO2 we produce in the first place. This can be done by using renewable energy, like solar and wind power instead of fossil fuels, which create a lot of CO2 when burned.
By doing our part to remove CO2 and reduce our production of it, we can help keep the Earth a safe and healthy place to live for all of us.
