I'll try not to be too damning-with-the-facts, but getting the Tesla will help leave a usable planet for others to enjoy, both while you're alive and long after.

Please allow me to be blunt: the vast majority walking among us have no friggin' clue as to just how bad a situation we are in. The fossil fuel industry spread some money around beginning in the 80's and they have pulled off the most successful disinformation campaign in human history. Some of those involved have a small conscience and have shared documents, videos and emails here (WARNING: This documentary will likely make your blood boil):
Watch FRONTLINE's three-part documentary examining the fossil fuel industry’s history of casting doubt and delaying action on climate change.

It was in partnership with the BBC, so if words are more your thing, here you go:

TL;DR?
Due to feedback loops, it rests on the shoulders of the educated and well-informed to ACT if we are to fix our current path, a path which will greatly impact, if not destroy, our only planet.
If we don't ACT, just
who do you think will?!?
More "must see," fact-based sites to help you realize just how bad the vectors are:
Earth's surface temperature has risen about 2 degrees Fahrenheit since the start of the NOAA record in 1850. It may seem like a small change, but it's a tremendous increase in stored heat.

NASA is a global leader in studying Earth’s changing climate.

Or, if you're just more of a visual person, try this NASA gif on for size (and note the change in the second derivative near the end):
