The first law of thermodynamics defines heat as a form of energy and thermodynamic processes and hence can be conserved. In a nutshell the first law of thermodynamics explains how heat as a form of energy cannot be formed or shattered only can be transferred from a place to another as well as be converted to different forms energy.
According to the second law of thermodynamics, every cyclical progression has entropy which either increases or remains at a constant. This law generally places restraints upon the direction of heat transfer and the possible efficacies to heat engines.
The United States energy sources refer to different springs of the Americans energy to cater for their needs. This sources include coal (39%), natural gas (27%), nuclear (19%), petroleum (1%) among others.
Hydrologic cycle is the constant procedure by which water is distributed through the globe. Water evaporates from the large body masses, plants and animal and condenses at some point due to atmospheric pressure changes to come down as rain or ice in a continuous cycle.
Current U.S water use patterns refers to the different water management strategies employed within the United States in the quest to develop a sustainable water management culture. The U.S water patterns is a detailed record of water usage within America since 1950 up to date.
Current global water use patterns refers to the global statistics of water usage across different nations. These statistics for a major part of the international planning standards that help determine which part of the globe has a genuine need for water supply.
Issues with aquifer water use focus on the depleting water resource especially in the Ogallala aquifer due to human activity. Human activity has contributed considerably to the depletion of aquifer hence posing an imminent threat to agriculture that is a core economic input tool.
Riparian water rights entails giving water ownership to certain people who own land in the water path. It is a common law within the English nation such as Australia, Canada and America that gives these owners the authority to own water within their land.
Sources of inefficient land use refers to the different practices such as land wastage, grabbing, poor waste disposal, mining among other human activities that undermine the productivity of land. This is set of all activities that lead to poor land utility.
Measures to increase land efficiency in land use refers to the different ways of increasing the productivity of land with an objective of supporting economic growth and development. Such measure include commercial farming, infrastructural developments and land reclamation among others.
The value of land changes directly proportional to the tax policies adopted in a certain economy. Unfriendly tax policies lead to unaffordability of land due to highly inflated land prices.
The government role in preserving land is to ensure that private land developers do not encroach the public land. It is the role of the government to ensure that land owners have the credentials for their lands as per the law as well as ensure that land owners do not use their private portions in a way that can harm the environment.
Eminent domain is the right of the government to own private land upon compensation to the owner for public use. The private owner can either be compensation monetary value or given an equivalent amount of land.
Developments to ward off food insecurity refers to the different mechanisms adopted to increase food production in the quest to meet the enormous demand of food. Biotechnology and agribusiness are among the most successful developments of the century.
Genetically modified food stuff refers to food products which are biotechnologically engineered. These food stuffs must meet the international standards as per with world food organization for them to be deemed fit for human consumption.
Climate change has negatively affected food production. Global warming in particular has led to incredibly low crop yields across the globe.
The feast/famine cycle of agriculture output is more of paradox scenario. Millions of people across the globe are dying due to lack of food while others are dying in hospices because of obesity.
Typical wood-volume generation of forest is generation of forests with less or no environmental value because of human activity. Forest have been turned in to waste zones.
Value determination for forest tree entails the appraisal of the economic and environmental value that certain forests or trees have to the economy.
Forests and green species hold an irreplaceable place in the ecosystem because they transform solar energy in to useful nutrients for animals, they change the lifeless to living.
Measures to ensure forest sustainability focuses on securing the forest against human activity as other agents of destruction in the quest to maintain a sustainable ecosystem.
