Carbon Dioxide causes both climate change and global warming. I believe that global warming is an effect of climate change. Climate change has been affecting people in many ways over the last 100 years. The world has been getting by the year and has beaten the record for hottest year for consecutive years. Car emissions have worsened the environment and are causing places to have high volumes of co2 in the air. The Co2 levels are causing people to have to wear masks so that they don,t take in the toxic air. People are walking places and that's good because they are trying to lower the amount to help everyone else, so you should too. Instead of taking a car on a short commute, try riding a bike or walking. This can help the environment and slow down the global warming rates. Eventually everyone will own a tesla and well have no car emissions. Eventually we'll be able to go outside and not have to worry about Co2.
