A person always cares about the beauty, comfort and well-being of his home. We try to keep the air in our house clean and fresh, so that dust on the shelves and closets does not accumulate, the floor shines with its cleanliness, the plants in the apartment are pleasing with their green color; we add more colors in our home, picking up bright wallpapers and color accessories. When in the house order and cleanliness, it becomes light and comfortable in the soul. However, when we go out of our safe apartments to the street, this feeling of comfort and warmth disappears. City streets are overflowing with household garbage, the air is saturated with emissions of cars and enterprises, trees are becoming less and less vehicles. Birds appear less and less in cities, and only stray dogs seek food.
