The correct answer is the following.
Recycling is a necessity not a commodity.
Recycling helps to take care of the environment. As simple as it sounds. Right now, it is not a matter of we want to protect the environment. Today is a requisite if we really want to live on this planet for the years to come.
The Earth is very polluted, the weather is changing, the seas have environmental issues. Humanity must do its part to cooperate.
Let politicians do its job with the big industries and the legislation. Let people, the everyday citizen to do its part and cooperate with the protection of the environment.
Recycling is one way to do it. Cumbersome? Probably, but it really does not represent a big problem. It just takes minutes to recycle. It just takes a moment to recycle. Everybody has the time to go to the recycling stations and cooperate.
