Carbon Footprints - Carbon footprints is a catchphrase that is a general interpretation of the social impact on global warming. It stands for a certain amount of gaseous emissions that are relevant to climate change and associated with human production and/or consumption activities.
Ecosystem Impact - Effects of global warming can already be seen in the animal kingdom. Species that are being affected include Adelie penguins, butterflies, foxes, alpine plants, and spruce bark beetle.
Health Impact - The increased amount of carbon dioxide in the air increases our risk of allergy and asthma. Air pollution and increased pollen tends to make allergies worse, and increase smog in heavily industrialized urban settings.
