Oxygen Cycle

The nitrogen cycle represents one of the most important nutrient cycles found in terrestrial ecosystems. Nitrogen is used by living organisms to produce a number of complex organic molecules like amino acids, proteins, and nucleic acids. The store of nitrogen found in the atmosphere is about one million times larger than the total nitrogen contained in living organisms. Other major stores of nitrogen include This is mainly because most plants can only take up nitrogen in two solid forms: ammonium ion (NH4+ ) and the ion nitrate (NO3- ). Human activities are greatly increasing the amount of nitrogen cycling between the living world and the soil, water, and atmosphere. As a result of such activities, the rate of nitrogen entering the land-based nitrogen cycle has doubled. More...

Plastic Bags

  • It takes 430,000 gallons of oil to produce 100 million plastic bags, according to Worldwatch Institute.
  • Environmentalists estimate that plastic bags could take anywhere from 500 to 1,000 years to disintegrate.
  • China consumes 37 million barrels of crude oil each year to manufacture more than one trillion plastic bags.
  • The plastic industry in the US alone is $ 50 billion per year
  • Each year, an estimated 500 billion to 1 trillion plastic bags are consumed worldwide. That comes out to over one million per minute.
  • Hundreds of thousands of sea turtles, whales and other marine mammals die every year from eating discarded plastic bags mistaken for food.
