Why AAP Government’s Odd-Even Car Formula is Good for the Environment

India is the seventh largest country in the world and almost 30% of its population resides in the urban areas according to the 2011 census.

Houseplants – Nemesis For Indoor Air Pollution

The energy crunch witnessed by the world in the late 1970s forced people to design and resort to energy efficient techniques and practices, which also included energy efficient buildings. Energy efficient housings brought in the trend of buildings which were super-insulated and had reduced free exchange of fresh air. It was eventually realized that these buildings having tighter and congested construction, sealed from outside air was more prone to accumulation of indoor air pollutants to dangerous levels, greatly affecting the40

Ability of Honeybees to Find the Flowers Affected by Diesel Exhaust: Research

The researchers at the University of Southampton, in the first week of October 2013 revealed that the ability of honeybees to find the flowers can be hindered by the chemical in diesel exhaust. The tests revealed that the diesel exhaust degraded the floral scent chemicals on which the honey bees foraged.
