The Green Revolution was the introduction of new crops and new agricultural technologies. It is called a revolution because of the extensive effect it had worldwide. It was caused by the need for improvement of overall living conditions. It brought about both positive and negative changes to society. It brought an increase in food supply, changes in lifestyle, and changes of the treatment of the planet.
The Neolithic revolution emerged around 12,000 years ago and occurred when civilizations began farming crops and domesticating animals (Feder, 2014). The societal shift helped civilizations to change from nomadic type lifestyles, such as scavenging and engaging in hunter-gatherer behaviors. The result was civilizations could locally produce the food needed to survive. This developed into a strategy of farming and then ultimately producing and collecting surpluses of food that had previously been more scarce or more labor intensive to obtain (Feder, 2014). The Neolithic revolution was the cornerstone of developing modern societies, as it marked a global scale socio-economic change which fast-tracked the rise of civilizations and social class divisions.
Besides economy, agriculture is required in industrial revolution because without it, three fundamental functions of industialization cannot be done. Three main functions mentioned by Hobsbawm are increasing production and productivity, providing more surplus substantial for the towns and industries and providing mechanism to add to the capital(Eric 1996, 47). In general, agriculture prepares both material and capital for the industrial revolution; therefore it is significant in the emergence and growth of
Introduction Climate change has become a major issue throughout the world lately. The rate of climate change is still increasing and more people are becoming aware of this undeniable fact. The shifts that are being observed in phenology, i.e. life cycle events of plants and animals could be explained by climate change. Individuals can change their phenotype in response to different environmental conditions through a mechanism called phenotypic plasticity.
Climate change is a very important aspect in the world we live in. It is a natural occurrence in which the earth is trying to adapt to the natural setting that is occurring at the moment and can be manipulated very easily. Imagine a balance scale, with one side being a hotter climate and the other side being a colder climate. If either sides of the scale are unbalanced, the world we live in would not be able to sustain life as we know it. Climate change has been occurring ever since the beginning of time, and has been on a constant rise ever since mankind was put on this earth.
I chose this topic because in the past few decades, a lot of natural calamities and phenomena have taken place, e.g. : untimely floods, global warming, habitat loss, etc. And many of these have been caused by urbanization and one of the biggest threats that it poses i.e. the loss of ecosystems. Both urbanization and ecosystem loss disturb the natural balance of planet Earth.
To find out how the existing legal framework on land use is contributing to changes in food production. 1.3.2 Research Questions 1. Has rapid urbanization led to change in land use in Kiambu county 2. Have employment levels within the agriculture sector in Kiambu county changed significantly due to
The level of carbon dioxide has been increased in the upper part of the atmosphere which it leads to increase the average temperature on the surface which it causes many problems in many side of life including nature, health and economy. Increasing the concentration of carbon dioxide is due to release of poison gases to the atmosphere by cars, manufactures, oil field, burning of natural gases and smoking. Air pollution and climate change are a result of increasing the level of carbon dioxide around the world. Researches show that the average temperature of the planet has been changed during the last decades, as a result, many problems join with it and climate change is considered as the biggest problem around the world. Climate change is one of the results of global warming and it has so many negative disadvantage impacts on earth, including; increasing the events of natural
One of the impacts of this growing population is an increase in land usage for settlement purposes. This means farmers will have to feed more people with less land. Economic development will also help increase the demand for food products. The biggest challenge facing farmers is to double their production with limited resources. Economic sustainability is an important aspect of sustainable agriculture.
Global Environment Problems Global environment can be defined as the environment about our nature and the surroundings that influence worldwide scale an environment could be a desert or polar land. Environment problems: Our environment constantly changing. There is no denying that, However, as our environment changes, so does the need to become increasingly aware of the problems that surround it. With a massive influx of natural disasters, warming and cooling periods, different types of weather patterns and much more, people need to be aware of what types of environmental problems our planet is facing. • Pollution: Pollution of air, water and soil require millions of years to recoup.
This period in time became known as the environmental movement- a time of great change and newfound maturity towards the environment. An increase in worldwide population and mass migration from rural to urban areas throughout twentieth century, placed growing demands on the environment.
This Neolithic Revolution was needed for the progression of human life. Changing to an agrarian based lifestyle created a larger population, an increase in food production, and a stable living environment. Humans transitioned from a hunter-gatherer lifestyle to an agrarian based settlement around 1000-9000 B.C. A sufficient amount of water is all it takes to sustain the hunter-gatherer way of life (McGee, 1895, 351). Even though the hunter-gatherer lifestyle was healthier for them, the farming lifestyle was more beneficial to them in the long run.
The increase in the number of sedentary farmers is primarily responsible for the leap in human population during the Neolithic transition. The transformation created changes that required the farmers to cultivate more and tend to more animals. Sedentary farming communities within the Neolithic enhanced technology that allowed social change to enter. Invention
As our modern technologies have advanced, with the increase in the use of plastic, rubber, oil and metals, our resources have been depleted. Because of this, many environmental issues have come about like pollution, climate change, global warming, deforestation, overpopulation, industrial and household waste, acid rain, ozone layer depletion, genetic engineering of food, and
