When it comes to environmental protection, everyone knows they should take effective steps to make a difference. However, the fact is that many of these measures are limited to hot air instead of concrete action. Isnít it worth our attention? I hold the belief that we need to come up some practical solutions and manage to turn them into reality, making our environment more pleasant. So please letís take our part, keep protecting environment in mind and go into actions!

Can any native teacher help me to polish the two underlined sentences?

Thanks
