What major environmental issue is associated with increased carbon levels?

Increased carbon levels, particularly in the form of carbon dioxide (CO2), are directly linked to global warming. This phenomenon occurs because CO2 is a greenhouse gas, which means that it has the ability to trap heat in the atmosphere. As the concentration of CO2 rises due to human activities such as burning fossil fuels, deforestation, and various industrial processes, it enhances the greenhouse effect, leading to an increase in Earth's average temperature.

This warming has several significant impacts, including changing weather patterns, rising sea levels, and increased frequency and severity of extreme weather events. It also contributes to changes in ecosystems and biodiversity, affecting species distribution and habitat conditions. The long-term consequences of global warming can be profound, influencing everything from agriculture to water supply and public health.

Eutrophication, acid rain, and ozone depletion are serious environmental issues, but they are associated with different processes. Eutrophication is primarily related to nutrient runoff leading to algal blooms, while acid rain results from sulfur and nitrogen compounds in the atmosphere affecting precipitation. Ozone depletion involves the thinning of the ozone layer caused by chemicals like chlorofluorocarbons (CFCs). Each of these issues has distinct causes and effects but does not directly correlate with the
