Your opinion was so attractive :) . 

But, I have a question about your opinion. As you said, eco-bags and tumblers can be harmful to the global warming. However, there are some research that the proper use of the eco products can cover its cons. 

Also, plastic bags or cups are very critical to the sea animals. Have you heard about the birds eating plastic foods? Like this , plastic trash float around the sea and attack sea animals. But, if you use eco products, you can just melt them or bury them in the ground. ( cause they decay easily ) which can help protecting sea animals. 

Then, can you say that using eco-products is bad for the environment, more than plastic ones? 

If not , isn't it better to use them to protect the earth? ( Rather than doing other things )
