People tend to care about their convenience more than the impact on the environment, so they won't take action to release the burden (wastes) to the planet. And they don't find contribution from one person can make any difference. And nothing is improved. That's my major concern to local environment. For global, some international leaders don't admit environment change. This is also bad for saving the planet.

I'll try to buy beverage with bigger bottle, so to avoid many smaller ones. I'll remember to use electricity receipt more often (sometimes I forgot..).

Most of the time, it's plastic bags (for bread) that's hard to avoid. I'll choose to buy something with bare packaging and put it in my reusable food bag.

Sometimes I prefer to bring a smaller bag which a mug or water bottle can't fit in. Sometime I'll bring a cup out when I know I want to take out drinks with me. But I wasn't always "predictable" when it comes to drink. That makes it hard to have reusable cup all the time. Therefore, I tend to NOT drink any thing if I can't have it with reusable cup. It is scary to learn how many disposal cups were wasted every day, so it is really a great accomplishment when I know I reduce waste and save the environment. 

I don't think I was addicted to sugar bit it does add flavor to what I like to eat/drink. By cutting it down to my diet, I feel fresh and found it not so bad to eat without it.
