Why is it sometimes difficult to make decisions involving economic development and the environment?

It is difficult to make decisions involving economic development and the environment because our conventional evaluation mechanisms including the market and government action are limited by insufficient information, cases of political pragmatism and the need to accommodate citizens’limited understanding. This makes it tough to reach a rational, well-informed decision that balances benefits and costs.

It is meant that like tapestry scientific theories often need to pull out since they are not relevant and often times the whole chain of theories may be pulled out.
