Reminder : we only have one sky.
Things offer both positives and negatives, but
a) generally those things are decided by local powers and authorities that can be influenced by local populations -- not corporations from specific countries that may or may not be far away and without local permission
(those decisions that are made by foreign corporations that modify local attributes is generally frowned upon -- very few like the oil rigs scattered around the ocean, they tolerate them due to the profits associated)
b) very few of these decisions create global impacts, the ones that do (say, environmental issues) have many confounding factors and influence groups working with them, representing many different people and locales.
In just so happens that in the case of 'the sky' we're all 'locals' -- but very few people, with respect to 'the world', had a say in the matter.
