Technically we are all hypocrites when it comes to putting CO2 into the atmosphere, unless you live in a cave. That doesn't really take away from the point nor does it invalidate the message.
+1, thank you. That is the point. I watched the movie and felt sick for what we are all doing. I too particularly enjoyed the part where the Indian lady almost slapped him for representing all of us in North America who are living a lifestyle of over consumption.
I want to show it to my kids but it is too depressing....hey dad, people are doing something, right? Me: I am not sure son.
If I ever meet Mr. DiCaprio I would shake his hand and thank him for realising that the indian woman was telling the truth. In the scene he sat there, looked embarrassed and then politely agreed with her. He didn't attempt any justification or any excuse. I think the truth of it hit home and it really hurt him.
As for the "people are doing something?" angle. I think there are a lot we can do locally.
Here are some things that may or may not be possible for everyone:
1. Eat less meat. This is a drop in the ocean act, but it will help if enough do it. Don't go vegetarian, just take the beef down a few notches and put in some fish and bit more vegetables. Bonus: It's probably healthier
2. Eliminate excessive energy usage. Turn off electric outlet when not in use, insulate your house, anything that saves energy will have an impact on fossil fuel consumption.
3. Take more local vacations. I'm not saying we should stop flying around the world, but we can all take it down a notch. We have changed our winter vacation habits so that we can drive our EV on vacation.
4. Discard your gas-burning vehicle and switch to something else. Our family has 2 electric bikes that we use 90% of the time and one long-range EV that we use for work. The long-range ev is very expensive but well worth it to us. This is a case of us putting a ton of money where our mouth is. But if you can make changes in your life to make a Leaf, Zoe, e-Golf... any EV work for you then do so. And if you have never ridden on an electric bike, go try it. It is awesome to say the least.
This might not make economic sense completely but it does make environmental sense and sometimes that is more important.
5. If you decided to go with option 4, then option 5 is to install your own renewables. Depending on your location this could be wind, photovoltaic or even water. If you live in an area with a "dirty" grid then this makes even more sense.
6. Now if you have installed renewables and feel like spending even more money you could consider getting a tesla powerwall. Again if you live in a dirty grid area this will reduce consumption of coal and it might even save you money. It's also a nice backup against a blackout. This may not be an investment, but it will help the planet.
Just what I could rattle off right of the top of my head.
