Global Food Security
a) Global Food Security
This is a global environmental issue that is taking the whole world by strides. With the increase in population globally, there is not enough food that can be used by humans. As a result, the environment like land is being forced to produce even in areas where production is difficult. There is also competition with the animals and this makes it difficult for humans to get the desired food to consume. Human activities that are leading to this problem are urbanization making land to be scarce for farming and also cutting down trees hence no rain for irrigation and farming(Carolan,2013).
Because of food security, populations are now getting to greenhouse farming. This is with the aim of making ends meet and for having enough food. With the construction of the greenhouses is evident that there is the emission of chlorofluorocarbons. These are the gasses that will normally lead to many problems and the common problem is the pollution of the gasses as there will be air pollution(Carolan,2013). The resulting issue is that there will be no enough food for consumption as it is difficult for it to grow. A good example is a farmer near a greenhouse where crops fail to produce.
With an increase in the global food security that is all over the world, there are ecological processes that are being affected. Of the four ecological processes, water cycle and nutrient cycling are the major ecological processes that are being left to defend for themselves. With lack of crop farming, there is no transpiration taking place leading to lack of enough rainfall. A good example is in the arid areas where there is no rain. Nutrient cycling is also not taking place (Lenne & Wood,2011). This is because there is no vegetation cover. As a result, microorganisms in soil are not getting involved in the nutrient cycle as the soil becomes much depleted and crops cannot produce as it should be.
