I think it's more about so many not seriously thinking about issues and also thinking that what they do doesn't impact the overall picture - such as, leave it up to governments. So quite often people aren't behaving deliberately bad or with bad intent, they often just don't consider the consequences of their actions.
No, I don't think we're being deliberately bad for the most part either. It's the system itself which is based upon greed, where you have individuals and people in positions of power where they are, often times consumed by it, hoarding wealth and not putting it back into the system, creating great and harmful economic disparities. The system itself becomes distorted and broken, and the average person who is a participant in that system (we all are), is not driven as much by that greed factor as those at the top are. But we still serve it and just assume everything the machine is doing to the world, which includes ourselves, will someone just work itself out magically.
Hey, it's not an easy thing, but it's the system we're all in. I think maybe we do have a moral obligation to act as the checks and balances of such a system by not buying products which harm the world. End the demand for it. But as long as we demand it, like must have a giant piece of meat for every meal, the system will give us what we want, and then create a wasteland. Basically, we need to step out and change the system, from the ground up, replacing the top with a more representative moral leadership, as opposed to corrupted agents of unchecked greed.
The whole thing is an interconnected tapestry, and we are all threads woven into it.
