The six criteria air pollutants are sulfur dioxide‚ nitrogen oxides‚ carbon oxides‚lead‚particulate matter and tropospheric ozone. These six pollutants significantly threaten human health‚ ecosystems and/or structures. 2. How is each produced? Sulfur dioxide is mostly produced from the burning of fossil fuels like coal and oil. It can also be released during volcanic eruptions. Nitrogen oxides are produced from vehicles as well as

on human population? The human population is more than 5 billion. It is the most abundant species which has a great competition from the insects and fishes. The human beings are adapted to the climate and edaphic factors. Most of the animals have a specific breeding period. But human beings and a few domestic animals have no such specifications. The animals with the specific period of breeding are frog‚ lion‚ deer and parrot. The human beings are quite active reproductively. Their population has

Eco Column Project Report VII. Conclusions a) In the aquatic chamber‚ the first week was a disaster. The plant life was sick‚ the snails were dying‚ and our fish died. As the project continued‚ it became healthier once we changed out the water. The first week the plant started flourishing‚ the snails and fish started to survive. In the decomposition chamber‚ it housed the entire time we started with leaves and some fruit which decomposed into the soil. When the project was over‚ it was
