The stripping of trees in a green lung in Bhubaneswar for a water project will have significant negative impacts on the environment. These include:

• Reduced oxygen supply: Trees play a crucial role in the production of oxygen, and their removal will lead to a reduced supply of oxygen in the area.
• Increase in pollution: Trees absorb pollutants such as carbon dioxide, nitrogen oxide, and sulfur dioxide from the air. The removal of trees will increase the level of these pollutants and contribute to increased pollution in the area.
• Soil erosion: Trees have deep roots that hold soil in place. The removal of trees will increase soil erosion and lead to loss of topsoil and nutrients.
• Impact on wildlife: Trees provide a habitat for wildlife such as birds and insects. The removal of trees will lead to a loss of habitat, reducing biodiversity in the area.
• Climate change: Trees absorb carbon dioxide and release oxygen. The removal of trees will result in increased carbon dioxide levels, contributing to climate change.

To mitigate these negative impacts, environmentally sustainable alternatives to the project must be considered. One alternative could be to relocate the project to an area where trees do not need to be removed. Another alternative could be to plant more trees in the area to compensate for those that will be removed. Finally, employing a sustainable approach to the project by utilizing alternative and less invasive technologies such as rainwater harvesting can avoid any potential environmental impacts.
