For example: most of SE Asia burns their rubbish in their back yard, because there are no rubbish collection facilities. They also litter, throwing plastic waste into the gutter, because they're too busy dealing with other stuff to care. But the wealthier countries (Singapore is the classic example) don't do this and are fastidious about waste management.
It doesn't matter what issues (or proposed solutions) you look at - it could be GMOs, glyphosate, plastic, electric cars, nuclear power, bio-fuels, you name it - there is no easy answer. Some solutions are better than others, but all have some disadvantages.
It certainly doesn't help the environmental movement that many of its members display a very definite "green ideology". They go around spouting their preferred policies, ignoring or shouting down any objections (no matter how well founded). That really doesn't help our trustworthiness with the rest of society.
The nature of politics is such that we often have to pick sub-optimal solutions, and often on incomplete knowledge. But let's at least have a proper debate before settling on one solution - and not prematurely tout anything as "the only green way to go".
