The article talks about the harmful effects of greenhouse gases on the environment, caused mainly by human activities like industry and transportation. It introduces the concept of a "carbon footprint," which measures how much greenhouse gases are being released because of these activities. The methods for calculating carbon footprints are being improved to help manage these gases better. In the future, it's crucial to keep working on better ways to measure the impact of human actions on the environment beyond just greenhouse gases. By understanding and reducing our carbon footprints, we can protect the planet from the dangers of climate change and ensure a healthier environment for all.
