1 Current agricultural practices are far from sustainable. If the growing population is to be fed we must revise the current practices‚ mainly animal agriculture. Cutting down or out the practice of animal agriculture can save enough water to supply an increase in the far more sustainable organic farming. It is seriously unfortunate that the political leaders of today are so distracted by terrorist attacks‚ immigration‚ and spreading rumors about each other‚ that no one seems to be mentioning the

Photosynthesis Green plants absorb light energy using chlorophyll in their leaves. They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration‚ or converted into starch and stored. Oxygen is produced as a by-product. The equation for photosynthesis: Carbon Dioxide + Water (+ Light Energy) → Glucose + Oxygen Symbol equation: 6CO2 + 6H2O ------> C6H12O6 + 6O2 (http://www.bbc.co.uk/schools/gcsebitesize/science/add_aqa_pre_2011/plants/plants1

Chemistry has been called the science of what things are. Its intent is the exploration of the nature of the materials that fabricate our physical environment‚ why they hold the different properties that depict them‚ how their atomic structure may be fathomed‚ and how they may be manipulated and changed. Although organic reactions have been conducted by man since the discovery of fire‚ the science of Organic chemistry did not develop until the turn of the eighteenth century‚ mainly in France at

Most Americans have no idea what is going on in the world of agriculture. All they know is that they go to the super market‚ buy their food‚ and eat to their heart’s content. We have become a well fed society because of the agricultural changes in the past century. Can we go further? Technology has allowed the farming industry to reach many milestones‚ but what does it hold for the future? As we continue our fight against world hunger‚ many seemingly simple technical advances could make a difference

Effects of Agriculture on the Environment Introduction: Agriculture has changed dramatically‚ especially since the end of World War II. Food and fibre productivity rose due to new technologies‚ mechanization‚ increased chemical use‚ specialization and government policies that favoured maximizing production. These changes allowed fewer farmers with reduced labour demands to produce the majority of the food and fibre. Humans‚ like all other species‚ exploit their surroundings for the resources they

INORGANIC CHEMISTRY – CLASS XI (ISC) Properties of Group 1 elements [Alkali metals] 1. Due to high reactivity‚ alkali metals do not occur free in nature. Elements of group 1 (or IA) are known as alkali metals because their hydroxides are soluble in water and form strongly alkaline solutions. Alkali metals are stored under kerosene oil because they get tarnished on exposure to air. 2. The general electron configuration of alkali metals is ns1. 3. Alkali metals have largest size and lowest
