Zosilnen\u00e1 \u017eiara br\u00e1ni tomu, aby sme ve\u010der mohli vidie\u0165 oblohu posiatu jasn\u00fdmi hviezdami. V\u00a0dne\u0161nom svete je to takmer nemo\u017en\u00e9. Ke\u010f sa pozrieme na \u010d\u00edsla, 99% Eur\u00f3py a\u00a0Ameriky zalieva svetlo aj po\u010das najhlb\u0161ej noci<\/strong>.

Hoci sveteln\u00fd smog \u010dasto ost\u00e1va bez pov\u0161imnutia, nesmieme zab\u00fada\u0165 na jeho n\u00e1sledky. Postupn\u00e9 zmeny viete urobi\u0165 aj vo va\u0161ich dom\u00e1cnostiach.
