'Creo que es necesario que vayamos en bicicleta o andemos para reducir la contaminación.'

Your use of the subjunctive looks okay to me, but of the vocabulary no.

Andar means to move about, to travel, which can be to walk, but here it is lost to me. Normally you would say andar en bicicleta here, and then use caminar for walk. You could use ir en bicicleta but it is not the norm- andar or montar are much more common.

Creo que es necesario que andemos en bicicleta o caminemos para reducir la contaminación.

As a general statement it can be written without subjunctive:

Creo que es necesario andar en bicicleta o caminar para reducir la contaminación.

This is only my opinion as an intermediate level learner, and it is possible that I have made an error in what I have written.

I think she does mean "It's necessary to go by bike or walk to reduce contamination. I see nothing wrong with her original sentence. - Daniela2041, Oct 10, 2015

I agree with Dani, remember that "andar" means "ir dando pasos / ir de pie". After the original meaning it is used idiomatically... Usage without subjunctive is not because it´s a general statement but because of usage of infinitive ...... - 005faa61, Oct 10, 2015

...... I think that´s what you mean - 005faa61, Oct 10, 2015

I also think ' andar' is fine.. - annierats, Oct 10, 2015
