I need some assistance with these assignment. sustainability as a term that has widely been used in most aspects of life Thank you in advance for the help! Consequently, agriculture has been documented as one of the most crucial modes of economic life that continuously sustains life across the globe. According to Baldwin (23), before the evolution of agriculture, the ancient man depended on hunting and gathering, and as a result, he was able to feed around 4 million people who were present at the time. Today, it is believed that agriculture has fed over 6,000 million people. In addition, evolution has generated more cereals as compared to the past four decades. In light of this, there has been increasing in the input of fertilizers, water and pesticides, new crop strains with the inclusion of other essential technologies that are related to the Green Revolution (Tilman et al 672).

Moreover, an expert in agricultural sector argues that by 2050, the population estimate will have gone up by 50 % thus, increasing the level of food demand across the globe by almost a similar percentage. As a result, there will be an increase per capita income and dietary shift in regard to high meat proportion. Of importance to note is that doubling the production of food and sustaining its production is the most challenging factor to deal with.

According to Lighthouse (21), practising agriculture becomes the main determinant of food production and the extent to which global environment stands at, in terms of usable and non-usable land. It is estimated that half of the usable land has been put in pastoral and intensive agriculture. As such, the practice is generally argued to cause a loss in the natural ecosystem, detrimental amounts of nitrogen and phosphorus to terrestrial ecosystems at rates that are likely to increase three times especially when past agricultural practices are incorporated.
