How green I am?

I remember when I was a child my parents told me all the time and taught me to be careful using water. That's a value I still have about consuming water and the same with the electricity. Besides that, I didn't learn about environmentally friendly practices at school or high school.
Actually, I've learnt to recycle and reuse my papers at the university and this method helps me to spend less money in materials. Other way, at home I have a box with all the sunflower oil wasted, to then, throw it into the ground because 1 litre of the oil we use cooking contaminates 1.000 litres of seawater if you throw it into the dishwasher.
Moreover, I ride my bike to go to the University everyday, unless it's rainy or when I have to carry a lot of stuffs. And in my opinion this is a good way to earn money because the public transportation is more expensive everyday.
About supporting an eco-organization I only have signed for Greenpeace online and I receive e-mails to support them almost every week.
Also, when I lived with my older sister we used to take all the tetrapack to the recycling area at the supermarket. One thing that I would like to do, is to reuse plastic doing stuffs really cool for example, once I saw a couch made of plastic bottles (the inside was made of it, then covered with a pretty and soft fabric), or a lamp made of plastic spoons, both were very pretty!.
I think I have reduce my carbon footprint riding my bike, being careful with the lighting electricity and water at home, and also, in every place I go. I don't take long showers, I don't use chimney or any home heating and air conditioning either. Also, I use the same plastic bottle with my own juice or water and not to buy a new soda.
Finally, I think in our city we don't have environmentally practices because some people don't know about it and when we were younger nobody teach us how to do it. But now, you can see how to recycle at home in TV programs or on the internet and there's a lot of people recycling and making changes in our environment. And actually, at primary and secondary school teachers are more dedicated to teach the kids to be committed with the environment that surround us.
