Litter

Litter is all waste that occurs in places that are not intended for that purpose, for example on the street, in the roadside, on the beach or in nature parks. It is waste that usually ends up there (unconsciously or consciously), through negligence, or through nature (water and wind).

Litter mainly consists of packaging materials from consumptions, for example, cans, bottles, wraps or chip trays. This is also called coarse litter. Cigarette butts and chewing gum are often left on the street, in parks or along the road and form the most important part of the category of fine litter. The third category of litter consists of bulky waste; large and/or heavily discarded waste.
It takes a very long time for litter to disappear from the environment, and the degradation time of waste is highly dependent on the material, the environment, and the weather conditions. Biodegradable waste disappears the fastest, but even in that case we still speak for months to years. For example, it takes one whole year before a banana peel is completely broken down, chewing gum needs at least 20 years to perish, and a cigarette butt needs 2 to 12 years to be destroyed by nature, and even then plastic remains can be removed from the filter. the environment. Plastic and metal are not biodegradable and can only be broken down by chemical processes, such as weathering and oxidation, photodegradation, etc. A tin can rust away after more than 50 years, but stainless steel, glass and styrofoam objects can remain in the environment for thousands of years. During this time they can cause nuisance or even danger for humans, animals, and the environment. Moreover, the degradation products of plastic material (also known as microplastics) are often themselves also harmful, and can easily be absorbed into the food chain.

Citizens often get annoyed by litter. Litter is an environmental problem and a problem for the living environment.
Beast
The word has multiple meanings. In the context of the above context, I find that this is not an animal but a human being, namely a rude behavioral person.
So beast what is you doing ??
