My name is Selvi, and I am from the Kanchipuram district. The primary reason for global warming is the increase in greenhouse gases, particularly carbon dioxide. Normally, humans consume oxygen and exhale carbon dioxide, but nowadays, our generation is releasing excessive amounts of carbon dioxide into the atmosphere. The main culprits behind this are the emissions from vehicles, which produce large amounts of gases, as well as deforestation, mining, cattle farming, and the automobile industry. These human activities are not only harming the environment but also contributing to the increase in global warming, which is having a devastating impact on our planet.
