WATER PROCUREMENT Water is one of your most urgent needs in a survival situation. You can‘t live long without it‚ especially in hot areas where you lose water rapidly through perspiration. Even in cold areas‚ you need a minimum of 2 liters of water each day to maintain efficiency. More than three-fourths of your body is composed of fluids. Your body loses fluid as a result of heat‚ cold‚ stress‚ and exertion. To function effectively‚ you must replace the fluid your body loses. So‚ one of your first

reproduce or grow in a particular environment. There are two types of successions primary and secondary. Primary succession is when an area that was not occupied previously is occupied by a new community. Secondary succession starts where natural vegetation is disrupted by humans‚ animals‚ or natural forces. Examples of ecological succession are fires‚ wind storms‚ floods‚ earthquakes‚ tornados‚ and forest fires. Energy flow between trophic levels is another ecological concept. Trophic levels are

Site Investigation Site Investigation is the gathering of information about the proposed location of the construction project. The reason for this can be twofold‚ firstly to assist in the location of the project and secondly to ascertain ground conditions. A site investigation should be taken for every site. Without a properly procured‚ supervised and interpreted site investigation‚ hazards which lie beneath the site cannot be known. A site investigation is made

The Amazon rainforest‚ evergreen‚ accumulates 10% of the world’s primary productivity and 10% of carbon in ecosystems. The fire in the Amazon deforestation in Brazil has been the top producers of greenhouse gas CO2. Brazil produces about 300 million tons of CO2 per year‚ of which 200 come from the burning of vegetation‚ although in recent years this country reduced to half the deforestation

Bushfires or wildfires have a high incidence in many regions of the world but is of distinct significance in Australia because the country’s high variant dry and arid landscape support the perfect environment for developing and sustaining these fires. Even though bushfires are part of natural dynamics in Australian environment‚ it is primary that learn from earlier wildfire emergencies to prepare and respond securely sooner or later with unexpected events. It has to be accredited by the communities

permanently frozen ground cover known as permafrost. The Arctic tundra is characterized by low precipitation and dry winds with some few kinds of grass‚ mosses‚ lichens and flowers. However‚ in general‚ the Arctic tundra is very cold with little vegetation cover. Due to the cold and permafrost‚ plant roots cannot penetrate to reach the soil. Arctic winters are dark and long as well as very cold. In the summer‚ however‚ temperatures may go above freezing point hence thawing and melting the top permafrost

The result is a very limited‚ but predictable‚ growing season when there is both sufficient soil moisture and adequately warm temperatures. Many plants are adapted to Vegetation: Throughout the world‚ the Mediterranean biome is characterized by shrubs. In most regions these shrubs are evergreen and have small‚ leathery (sclerophyllous) leaves with thick cuticles. Sometimes the leaves are so reduced as to appear needle-like

The effects of Deforestation on Our Environment Deforestation can cause many societal and environmental problems which can make our lives on earth even more challenging. Some of these challenges include: loss of biodiversity‚ the destruction of forest- based societies and climatic disruption. According to the 1992 United Nations Earth Summit in Rio Janeiro‚ biodiversity may be defined as‚ “the variability among living organisms from all sources including‚ inter alia‚ terrestrial‚ marine and other
