I'll make this short and sweet. These are the consequences for me not supporting the top five corporations on the Greenpeace polluters list.
Nestle can produce a bit of a challenge to everyone. Myself included. If the general population stopped using Nestle products all together the impact would be far greater than simply avoiding their bottled water products.
It's far easier for me to stay out of Tim Horton's locations as I'm not like 99.99% of the population that are hopelessly addicted to coffee. I never acquired a liking for the bitter liquid. To some people's surprise I have more of a sweet tooth than a bitter streak.
Their creamy chocolate chills, on the other hand, may provide a bit of a challenge. But I'm willing to sacrifice them until such a time as Tim Horton's does the right thing for the environment by providing a refillable 22 ounce cup to fit their large size cold drinks. All their refillable containers focus on hot beverages only.
In my opinion Starbucks is too pricey. So, that's not even a temptation.
McDonalds is only for the French fries. My body tells me I don't really need them anyway. Trying to avoid Coca-Cola products may prove difficult to some. But I have acquired a taste for tap water and fresh fruit home made smoothies. So my adjustment phase would be remarkably shorter than most.
Otherwise, for these corporate giants to have deadlines of five or ten years to implement significant changes to product packaging is simply not good enough when many see the damages done now as irreversible within that five to ten year period.
