Climate affects the cultivation of coffee or the impact of disposable paper cups on the planet, both of which are interrelated.

We have been boycotting "banning plastic bags" and "banning plastic straws", which has been implemented in supermarkets (everyone is starting to use environmentally friendly bags). Disposable coffee cups are one of the latest targets in this wave. Some people have called for disposable coffee cups to have the same warning signs as cigarettes.

So we thought we could take a look at the disposable coffee cup scene. Are they really harmful to the environment? Do we really have to get rid of them? If we don't use disposable coffee cups, what do we use?

Are disposable coffee cups with a reusable logo really harmful to the environment? To sum up, most disposable coffee cups are made of paper or cardboard, and these types of materials are not easily degraded. Although you might think, "Hey, these are not as bad as plastic."

Reason 1: disposable cups contain harmful chemicals, harmless to the human body, don't be nervous! But it is harmful to the whole environment. The cup usually contains a kind of polyethylene (which is plastic). Polyethylene doesn't have much impact on the environment, but it clogs the atmosphere-and they always run the risk of long-term accumulation of toxins.

Reason 2: even cups with recyclable marks can't be recycled quickly. Because disposable coffee cups are usually filled with drinks and remain in the cup even after being thrown away. This means that they are more difficult to recycle than other materials, which means that many disposable cups are not easy to recycle. So don't think it's just because there's a recyclable logo on your cup that it will be recycled automatically.

Reason 3: many trees (large area trees, all trees) are used when making cups. At the University of Melbourne, more than a billion coffee cups are used each year-and this is just Australia! Tens of millions of trees are destroyed every year, creating a product that can only be used once or can't even be recycled correctly.

Reason 4: the cup industry will have a large carbon footprint. All these recycling efforts have an impact, not to mention actually making them and transporting them. Factories, transportation, etc., actually have a huge carbon footprint. In fact, Starbucks did a study and found that every paper cup it makes produces 0.24 pounds of carbon dioxide.

The call to give up disposable cups is getting louder and louder. Of course, getting rid of these types of cups cannot be done overnight-cafes should not be blamed for using them. Because running a business is expensive, using these cups may mean survival.

Large chain stores such as Starbucks have introduced measures to allow customers to get discounts when buying coffee when using their own cups; some chain stores even ban disposable cups altogether

Brands such as Australia's KeepCup,FrankGreen, which have chosen to replace disposable coffee cups with portable coffee cups, are creating a more stylish and fun way to keep disposable cups off the market.
