Imagine you were going to build a “green” building. What features would it have? What would it look like? How would it harmonize
9966 [12]

Answer:

Green building is a modern concept in architecture by means of which it is aimed at construction developments that are not invasive with the environment, or that affect the ecosystem in which they are built as little as possible, with the aim of leaving future generations an intact environment worth living in.

Thus, for a construction to conform to this concept, it must follow the following parameters:

-The construction must adapt to the natural environment, and not this to the construction.

-It has to be resource-efficient. Furthermore, the materials used must not be exploited indiscriminately or causing damage to the environment.

-The external area of the building must respect the natural patterns of the area where it is built, favoring a harmonic view between the building and the surroundings.

-Use of clean and renewable energy to supply the building.

Why do companies like nestle object to bottle deposit programs? what do they support instead?
Ahat [919]

Answer:

The companies take away the bottle as "security deposit and however they can recycle and reuse it."

Explanation:

When buying different beverages from a person distributing, a deposit needs typically to be paid to the distributor from the containers that have been taken. However, the distributor will issue a refund once the bottle that was taken has been returned to the place of purchase. Therefore, the distributor will reimburse the redemption of the retailer the amount that was deposited for every container. The additional handling fees usually added in some countries. The deposits that remain unredeemed are taken to the state or kept by distributors.
