In my opinion, people can learn how to take care of our planet in many different ways, such as watching TV, reading flyers or earing it in the radio. Either way, I think people already know the speech but they rather do nothing about this, at least, here in Chile.
To be honest, I don't do much recycling in my daily life, but I always do separate my rubbish, in my building they have big different containers so I don't have any problem doing it. With transport, I don't do much, because I don't even know how to ride a bike so I can't save money that way.
Now, with organizations, no, I don't belong to any so I don't really know much about that topic. And well, to be honest I've never been really interested, I've always had the idea that these type of things demand a lot of time. To help the planet, I think I would like to help to create new green areas here in the city. Oh, and also learn how to ride a bike.
In order to reduce my carbon footprint I think I would try to use less water, use eco-friendly transport, use light bulbs that don't spend too much energy, etc.
To finish, I can say that our sociaty lacks of actitudes that help our environment, and in my opinion we should have more laws that promote this kind of behaviour.
