Recycling reduces waste and the need for new raw materials by reprocessing used items into new products. It helps conserve natural resources like trees and wildlife habitats by lowering the demand for timber, petroleum, and ore extraction. Recycling also decreases water pollution, carbon emissions, and the use of toxic chemicals compared to producing goods from virgin materials.

Krste Petkov Misirkov was a Macedonian patriot and scholar born in 1874 who made significant contributions to Macedonian culture and language. He published the seminal work "On Macedonian Matters" in 1903, which laid out principles for codifying the Macedonian language based on central dialects. However, the book was largely suppressed due to threats from those wanting to subjugate Macedonia. Misirkov spent much of his life in exile and died in poverty in 1926. He also published a magazine called "Vardar" and over 30 articles on topics related to Macedonia, its culture, and politics.
