CARBON DIOXIDE EMISSIONS
More and more products are currently manufactured using recycled materials. Common household items that contain recycled materials include the following:
Carbon dioxide (CO 2 ) is the main greenhouse gas that isemitted as a result of human activities. In 2017, CO 2 accounted forapproximately 81.6% of all greenhouse gas emissions in the US from human activities.
Carbon dioxide is naturally present in the atmosphere aspart of the Earth’s carbon cycle (the natural circulation of carbon between theatmosphere, oceans, land, plants, and animals). Human activities are alteringthe carbon cycle: both by adding more CO 2 to the atmosphere and by influencingthe ability of natural dissipators (such as forests) to remove CO 2 from theatmosphere and influencing the capacity of the land. to store carbon. Although CO 2 emissions come from various natural sources, emissions related to humanactivities are responsible for the increase in the atmosphere since theindustrial revolution.
