Rainforests are home to two-thirds of all the living animal and plant species on the planet. It is guessed that many hundreds of millions of new plants and insects are still un-discovered. Tropical rain forests are called the “jewels of the earth”, and the “world’s largest medicine cabinet” because of the large amount of natural medicines discovered there. Tropical rain forests are also often called the “Earth’s lungs”. Even with the growth of plants in a rainforest, the actual quality of the soil is often quite bad. Fast decay stops nutrients from collecting.
The under growth in a rainforest is usually very dark, because the trees block the sun. This makes it possible for people and other animals to walk through the forest. If the trees are cut down, the ground beneath is filled with vines, shrubs and small trees called jungle.
