In this regard, it is noted that a hectare of forest produces about 50 times more oxygen than the same area covered with grass or agricultural plants. Read the rest of this entry »

Water has represented and represents the essence of life. Water is the main factor within the planetary ecosystem.

The total volume of water on Earth is 1.35 billion km3 at surface + 8 million km3 in basement + 13.000 km3 in atmosphere. In percentage, 92.7 % of water is represented by the oceans, 2.15% is frozen water and 0.65% of water is represented as freshwater on Earth or atmosphere. Thus, freshwater constitutes 39.2 million km3 (2.7%) and is characterized by unequal distribution, and most of it must be be brought from polar areas. Read the rest of this entry »
