alternative water sources • cost of the rainwater harvesting system. When rainwater harvesting is mainly considered for irrigation‚ several factors should be taken into consideration. These include: • rainfall amounts‚ intensities‚ and evapo-transpiration rates • soil infiltration rate‚ water holding capacity‚ fertility and depth of soil • crop characteristics such as water requirement and length of growing period Although rainwater can be harvested from many surfaces‚ rooftop

GLOBALWARMING: NATURAL OR MANMADE? ------------------------------------------------- Saloni Gupta (Civil engineering Dept.‚ MediCaps Institute of Science and Technology) ABSTRACT: The ‘Mother Earth’ has been cooling for the last decade. Poles of the planet are gaining about as much ice as they are losing. It is worth mentioning that since past 420‚000 years‚ Earth’s atmospheric temperature is changing even before carbon dioxide emission by humans. There is no scientific evidence to back claims

Introduction: Global warming is gradually becoming a serious concern to our environment and our planet as a whole. Nature is now showing signs with unique changes affecting our lives. When the surface temperature of the earth heats up human beings are not the only ones who feel the changes and also react in some way. Animals and sometimes even plants will also be affected by the global warming. What is global warming: An overall warming of the planet based on average temperature over the entire

A tropical rainforest is an ecosystem that occurs roughly within 28 degrees north or south of the equator (equatorial zone between the Tropic of Cancer and Tropic of Capricorn). They are characterised by their humidity (average of 88% in the rainy season and 77% in the dry season)‚ hot temperature (average 27.9 °C during the dry season and 25.8 °C during the rainy season) but more importantly their extremely high rainfall (torrential rainfall - between 1‚500 mm and 3‚000 mm annually). Tropical rainforests

ends up with enough energy to ’escape’. Evaporation is an essential part of the water cycle. The sun (solar energy) drives evaporation of water from oceans‚ lakes‚ moisture in the soil‚ and other sources of water. In hydrology‚ evaporation and transpiration (which involves evaporation within plant stomata) are collectively termed evapotranspiration. Evaporation of water occurs when the surface of the liquid is exposed‚ allowing molecules to escape and form water vapor; this vapor can then rise up

70%‚ at removing air pollutants than smaller trees. Over the course of one year‚ trees removed an estimated 1‚821 metric tons of air pollution in New York City.Trees reduce surrounding air temperature and create their own microclimates through transpiration and the effects of tree canopies. Tree canopies not only provide shade but they also reduce solar radiation absorption and provide heat storage. The larger the tree canopy‚ the greater the reduction of surrounding air temperature.

Climate Change Unless you live under a rock‚ you will have noticed what’s happening around the human race due to global warming and climate modification. It is not only affecting us humans‚ it is also affecting our vegetation‚ our animals‚ and our oceans. I recently watched a video by National Geographic about the precious coral reefs in the Florida Keys and it talked about how the coral reefs cannot keep up with the rising sea level‚ so eventually they will all just die (“Fighting to Save Coral
