The document discusses how transportation contributes to global warming through greenhouse gas emissions. It notes that cars, trains, and planes rely mainly on petroleum as fuel, which is in limited supply and causes environmental problems. Transportation, especially personal vehicles, is identified as a major contributor to greenhouse gas levels. The document suggests ways to reduce this impact, such as using more renewable fuels like hydrogen, electric vehicles, ride-sharing, and reducing fossil fuel consumption over time.

2. What effect does Transportation
have on us Today?
• Public transportation is one of the biggest
supplier to global warming
