All OVER the world - устоявшееся выражение.
Big cities are always densely populated. You will never find a city without any plant or factory. They may produce necessary goods, but at the same time they are the main air pollutors in a city. This can become a global ecological problem if we don't invent the way of cleaning the air.
Plants and factories also pollute water in rivers and lakes. A polluted river loses its "population": fish and water grass, and becomes unavailable for rest and fishing.
While I am speaking about factories I don't except that people are the city polluters too. Nowadays every fourth person owns a car, which also pollutes the air. There are some people who drop litter in parks and even in streets. This litter will not disappear immediately. (время заканчивается, сейчас добавлю остальное)

Go outside on a sunny day and look at your shadow! Early in the morning and late in the afternoon, it is long. At lunchtime, it is very short.
This is because the Earth moves around the sun and the sun is in a difference place in the sky at difference times of the day. Sundials use shadows to tell the time. They are the oldest way to tell the time.
<em>Выйдите на улицу в солнечный день и посмотрите на свою тень! Рано утром и поздно днём она длинная. В обед очень короткая.</em>
<em>Это потому, что Земля двигается вокруг солнца, то есть солнце в разное время находится в разном месте. Солнечные часы — это тени, по которым узнают время. Это самый древний способ узнавания времени.</em>
