Consider the following statements regarding the impact of greenhouse gas emissions on Earth's orbital environment:
Statement I: Increasing levels of human-caused greenhouse gas emissions in the atmosphere may reduce the total number of satellites that can safely orbit Earth.

Which one of the following is correct in respect of the above statements?
1
Both Statement I and Statement II are correct, and Statement II is the correct explanation for Statement I.
2
Both Statement I and Statement II are correct, but Statement II is not the correct explanation for Statement I.
