Thomas va chez ___________ oncle (adjectifs possessifs)

Hi all.  Can someone advise me as to when one uses ça as 'it' rather than le, la, l' eg. je le déteste or je déteste ça?  I have just done an exercise where the latter was used for 'I hate it', I would have used 'le'.  I can understand it being used for I hate 'that' but here it was used for 'it'.  Thanks in advance/ merci en avance, Kevin

why is 'ça' used to refer to 'le recyclage' and not 'il'? Like 'Il réduit la pollution' for instance or 'il limite des déchets'?

These exercises are so helpful. Could please explain the usage of "en" in the phrase "Si j'en avais les moyens?" Why is not simply "Si j'avais les moyens?" 

In a search to demystify the difference between savoir and connaître, I stumbled upon an article earlier that suggested something along the lines of "use connaître when you've had prior experience with something" with one of the examples being "vous connaissez [name of place]?" meaning have you been to [name of place]? instead of asking whether the person is aware of the existence of said place. The second example was "Je connais Brad Pitt"; a statement that implies that one has met Brad Pitt before rather than plainly saying that they know of the existence of him. Since this lesson hasn't mentioned anything regarding what I've said above, can anyone enlighten me on this matter? 

My answer to a question in the quiz wasn't in the dropdown. Please could you explain why the phrase My little boy is in kindergarten uses 'en' instead of mon petit garçon est à l'école maternelle? Thank you.
