1 00:00:02,290 --> 00:00:09,289 In this video, we are going to learn about the human impact in the environment, especially in forests. 2 00:00:09,289 --> 00:00:39,149 Talk about forests. A forest is an area with a lot of trees. 3 00:00:39,149 --> 00:00:45,149 There are forests all over the world. There are different types of forests. 4 00:00:45,149 --> 00:01:07,019 Equal forests vary depending on the location of the forest. 5 00:01:07,019 --> 00:01:14,019 For example, there are tropical rainforests, coniferous forests, and deciduous forests. 6 00:01:14,019 --> 00:01:49,209 These can occur naturally, but they can be affected positively and negatively by human behavior. 7 00:01:49,209 --> 00:02:02,730 If a forest is carefully replanted and allowed to grow, it can exist in balance. 8 00:02:02,730 --> 00:02:49,129 However, if the forest is cut down faster than it can grow back, then it will be used up quickly. 9 00:02:49,129 --> 00:02:53,689 Forests serve as home to many of the organisms that live on the land. 10 00:03:02,099 --> 00:03:06,659 Forests are also very important because they are major contributors 11 00:03:06,659 --> 00:03:10,020 to recycling and cleaning the world's supply of oxygen. 12 00:03:11,620 --> 00:03:17,139 Forests, jungles, trees, plants produce the oxygen we breathe. 13 00:03:18,020 --> 00:03:22,740 They are the lungs of the earth. We destroy them, we destroy ourselves. 14 00:03:22,740 --> 00:03:54,979 Also provide wood, which is useful both as a construction material and as a fuel source. 15 00:03:54,979 --> 00:03:59,180 Now investigate and answer these questions.
