Disadvantage: Lack of Water. Lack of water, the most evident disadvantage to deserts in general, results from the combined effects of insufficient rainfall and rapid water evaporation by nearby land masses. The rate of rainfall rarely exceeds the rate of evaporation, and it is not uncommon for rain to vaporize even before hitting the ground.
As previously mentioned, recycled products may contain toxic chemicals that were previously present with the original material. 6. Generally ineffective. As shown above, recycling results in more pollution, higher energy consumption, and cost-inefficiency, making it less effective than what everyone wants to believe.
The Science article mentions several species of terrapin, which lay their eggs in the same beaches every year. These nesting sites are disturbed and even destroyed by dredging. Gharials, a critically endangered species of crocodilian, are also threatened by sand mining. Gharials lay their eggs in riverside sand, and young gharials rely on ...
Dredging is the process of removing accumulated sediment from the bottom or banks of bodies of water, including rivers, lakes or streams. Dredges are specialized pieces of equipment that create a vacuum to suck up and pump out the unwanted sediment and debris. Sedimentation is a naturally occurring process where silt, sand and other …

When oil hits the environment, it can pollute water resources, crop lands, and the environment in other ways. That is in addition to the emissions that oil energy creates when it is consumed. 3. It can cause health hazards when consumed at high levels. Combustion is the most common form of consumption for oil energy.
Higher-strength. Greater durability. Disadvantages of manufactured sand: Higher cost. More requirement of water-cement due to its smooth and angular texture to achieve appropriate workability. Presence of more amount of micro-fine particles that adversely affect on strength and workability of concrete.
Advantages. Firstly, In terms of accuracy, this algorithm is comparable to C4.5 on voluminous UCI benchmark datasets. KStar performs better and with a higher speed than C4.5 on big numbers of text classifications. Thirdly, this algorithm is low in time complexity that means it is very fast.
