The Pepsi story basically shows that business is all about money and profits. They don't care about our environment. If they can use the environment to market their business for profits, they will, but they'll never care about our environment unless we make them. Businesses will only ever change their ways if laws become more strict.
I envision a future where governments can create and enforce stricter laws that can get companies to make more sustainable and environmentally friendly choices.
But I also know that this starts with us. We have choices we can make, for example, boycotting businesses that are not making sustainable choices. We need businesses to realize that they can't function without us, the consumers, so if we boycott them due to their bad sustainable choices, they will have no choice but to change their ways.
