Today I watched a video about a phenomenon I haven't heard of before - light pollution. It turns out that artificial light which illuminates our cities is used excessively and has harmful effects on ecosystems, as well as on human health. For instance, turtle hatchlings have more difficulty with reaching the sea. They are supposed to rely on Moon's glow but city lighting makes them disoriented to the point that some may never find their way. Excess light also impacts humans - it may lead to sleep depriviation, damaged eyesight or even cancer, as it affects our cells negatively. I found the information very interesting. The topic is not mentioned often but seems to be an important issue.

Many people, including me, agree that noise is disruptive to concentration.
I was overwhelmed with joy when I heard that I won the competition.
