Greenhouse Effect & Global Warming

The average global temperature has risen about 0.50C in the last century, and scientists expect another increase of 1 to 40C in the next 100 years due to increasing pollution in our atmosphere. Greenhouse Effect: * Greenhouse gases allow the passage of incoming solar short-wavelength radiation but absorb some of the reflected infrared radiation and… View Article

Ecocriticism Study

Ecocriticism is the study of literature and environment from an interdisciplinary point of view where all sciences come together to analyze the environment and brainstorm possible solutions for the correction of the contemporary environmental situation. Ecocriticism was officially heralded by the publication of two seminal works,[citation needed] both published in the mid-1990s: The Ecocriticism Reader,… View Article

Environmental Science

Our world looses 40,000 species a year, while ocean fisheries collapse and global warming threatens ecosystems from the coral reefs to the melting of the North Pole poles to the grain-producing mid-latitudes. There is a greater need than ever before to understand ecosystem processes, man’s impact on these processes, and the value systems that will… View Article

Ecological Evaluation of Environmental Problems

Biodiversity refers to the abundance of life forms (bio means life, diversity means variety or assortment). This includes different animals, plants and micro-organisms. The ecosystem where these living organisms belong, as well as their genetic make-up, is also part of biodiversity. Wide biodiversity is advantageous to species development as there will be various interactions going… View Article

Ecological Succession

As long as the earth has existed, changes have occurred in the natural landscape. Ecology, a term created in the 19th century from the Greek “ oikos” (household) and “logos” (study), is the study of nature as an orderly system of interaction between plants and animals with their environments. (Allen, 4).      These changes in… View Article

Wetland And Water Environment

Green culture in Mexico

Today humanity uses the equivalent of 1.5 planets to provide the resources we use and absorb our waste. This means it now takes the Earth one year and six months to regenerate what we use in a year. Mexico City generates more than 12,500 tons per day of solid waste and the % 50 of… View Article

Food Chains, Food Web, Ecological Pyramids

In an ecosystem, plants capture the sun’s energy and use it to convert inorganic compounds into energy-rich organic compounds. This process of using the sun’s energy to convert minerals (such as magnesium or nitrogen) in the soil into green leaves, or carrots, or strawberries, is called photosynthesis. Photosynthesis is only the beginning of a chain… View Article

Mediterranean Woodlands Ecosystem

An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment interacting as a system. These biotic and abiotic components are regarded as linked together through nutrient cycles and energy flows. As ecosystems are defined by the network of interactions among organisms, and between organisms and their environment, they… View Article


Generally, eutrophication occurs when the rate of nutrient accumulation is greater than the rate of nutrient removal (Heggie, 2006). Because of unnecessary high nutrient content of the soil, plants experience stunted growth, (as indicated in some of its salient features) fishes die in rapid succession, and a general deterioration of water quality. Nitrogen and phosphorus… View Article
