I am an environmental scientist and the simple answer is that it lies in EACH of OUR hands. It is not a problem that can be foisted onto some agency or organization. It is a matter of personal responsibility for the environment.
BTW, I DO cycle or use public transport every day even though using a car would be quicker and more convenient, I DO separate and recycle my rubbish assiduusly, I DO pay the extra for organically grown food and I do as far as I can choose NOT to buy goods that I know are harmful to the environment or that are unsustainable. I cannot promulgate a solution unless I am prepared to abide by it myself.
