In this video, we are going to learn about the human impact in the environment, especially in forests.
00:00:02
Talk about forests.
00:00:09
A forest is an area with a lot of trees.
00:00:41
There are forests all over the world.
00:00:44
There are different types of forests.
00:00:47
Every forest varies depending on the location of the forest.
00:00:50
For example, there are tropical rainforests, coniferous forests, and deciduous forests.
00:01:12
They can occur naturally, but they can be affected positively and negatively by human behavior.
00:01:19
If a forest is carefully replanted and allowed to grow, it can exist in balance.
00:02:07
However, if the forest is cut down faster than it can grow back, then it will be used up quickly.
00:02:13
Forests serve as home to many of the organisms that live on the land.
00:02:59
Forests are also very important because they are major contributors
00:03:12
to recycling and cleaning the world's supply of oxygen.
00:03:16
Forests, jungles, trees, plants produce the oxygen we breathe. They are
00:03:21
the lungs of the earth. We destroy them, we destroy ourselves.
00:03:28
also provide wood, which is useful both as a construction material and as a fuel source.
