Yours is perfectly fine, but I'd like to add some punctuation and add a few more lines for your help. I hope it satisfies you!
"Even though private cars are chosen over public transport, and, private cars can take us to our destination in half the time, an increase in the number of cars is not eco-friendly. Cars require fossil fuels, which take millions of years to form and can take seconds to use. When fossil fuels are burnt, they produce harmful gases which damage the ozone layer and are one of the major causes for climate change and global warming.
There are also pros and cons for public transport. It's affordable and also environment friendly since the number of fossil fuels being used will reduce. However, public vehicles can be very crowded and have long wait times.
The conclusion we draw here is that most people prefer having private cars/vehicles over public transport."
I tried my best, good luck!! :3
