Delivering haraam items

Q: I want to ask about earnings from food delivery services in a non Muslim country/community. Uber Eats, Door Dash are the delivery service name. 

The delivery is not containing any alcohol, etc. but sometimes some foods containing pork products. Either cooked or sometimes grocery items contain bacon, pork products, etc. Are the earnings halal or permissible by a Muslim?

Taking flowers from public places

Q: Please can Mufti Saheb let me know if it is permissible to take flowers etc. from public spaces like the beach, empty public fields or on the side of the road. 

Certain plants are bulb types - meaning they multiply as the years go. Can you take a few of these wild bulbs home to plant in your own garden? 

Can you take some grass for example with part of the root attached to replant? No damage will be caused in these cases to the other plants and also there will still be many more of these plants left in the area.

Selling rizla

Q: I have noticed that my father has been selling filter/rolling paper (rizla) in bulk such as in large boxes to possible retail customers. I would just like to know whether it is permissible to sell such an item given the nature of its use?
