Damaged ecosystems are everywhere where people have built homes, developers have built condominiums and office building, and also where people drill for oil and extract precious resources. Today it is important to find solutions to restoring these damaged ecosystems back to natural habitats. The answer...
Factors that limit life at different depths in aquatic life zones
By: Dr Pandula Siribaddana
Aquatic ecosystems are classified broadly into marine and fresh water ecosystems. The marine ecosystem covers around 71% of the earth’s surface while freshwater ecosystems cover around 0.8% of the earth’s surface. The life in aquatic ecosystems can be variable from one place...
Reasons why some have called global warming a hoax
By: Stuart Cockerham
While most that support the idea that man is largely responsible for this increase in temperature contend that it is because of the increase in CO2 levels due to the burning of fossil fuels. Although CO2 levels have increased during this same period, there is...

Global warming and the potential effects on crop growth
By: Jose Juan Gutierrez
Global warming and agriculture are closely interrelated. Global warming is believed to have significant impact on factors affecting agriculture, such as temperature, soil fertility, length of growing season, glacial retreat, carbon dioxide, and precipitation. These factors determine the ability of the biosphere to produce enough...
The relationship between solar activity and climate change
By: Brian Lobb
The beauty of science is the fact that most scientists are skeptical by nature and what was once thought of as fact, can then change and be replaced by a new fact. In 2006 Pluto, the ninth planet of our Solar System was changed from...
Factors that limit life at different depths in aquatic life zones
By: Colette Georgii
Limiting factors in aquatic life zones are sunlight, water temperature, oxygen, and nutrients. Depending on the amount of sunlight that filters through the water, the varying temperature of the water, and the amount of oxygen in the water; sea life will live or die according...
Factors that limit life at different depths in aquatic life zones
By: Gioia Degenaars
The ocean is filled with a variety of life. People are learning more and more about the Earth's great oceans as they are able to reach depths that were never possible before. They are finding life where they did not believe life was possible. The...
