Forest have been called the 'lungs of earth' because growing trees take carbon dioxide out of the air and replace it with oxygen. This is vital for humans, as we need oxygen in the air to breathe. As lungs take out the carbon dioxide from the body and supply oxygen to all parts of our body via nerves. Similarly forests also absorbs carbon dioxide from the surroundings and extract the oxygen from the trees.

• A forest is a large area dominated by trees. Forests are the dominant terrestrial ecosystem of Earth, and are distributed around the globe. Forests account for 75% of the gross primary production of the Earth's biosphere, and contain 80% of the Earth's plant biomass.
  
• Forest helps in controlling the flow of water and slows it down which helps in preventing flood. Also, the trees present in the forest prevents the rain from directly hitting the ground and bind the soil together which helps in absorption of the rain water and thus prevent flood.
  
• Trees also prevent soil erosion.

The variety of plants which are found in a particular region at a time is known as flora. This flora includes all the type of plant life and can be organised into different categories as native plants, agricultural, horticultural, floral and weeds. The flora of a particular region at a time is documented and then published. This helps to maintain a record of the type of plants in the region which existed at a particular time.
