Answer:
Greenhouse gases from human activities are the most significant driver of observed climate change since the mid-20th century.1 The indicators in this chapter characterize emissions of the major greenhouse gases resulting from human activities, the concentrations of these gases in the atmosphere, and how emissions and concentrations have changed over time. When comparing emissions of different gases, these indicators use a concept called “global warming potential” to convert amounts of other gases into carbon dioxide equivalents.
Explanation:
Why does it matter?
As greenhouse gas emissions from human activities increase, they build up in the atmosphere and warm the climate, leading to many other changes around the world—in the atmosphere, on land, and in the oceans. The indicators in other chapters of this report illustrate many of these changes, which have both positive and negative effects on people, society, and the environment—including plants and animals. Because many of the major greenhouse gases stay in the atmosphere for tens to hundreds of years after being released, their warming effects on the climate persist over a long time and can therefore affect both present and future generations.
According to the research, the correct option is contour farming. It is the agricultural technique which involves turning the soil over and parallel to the hill in order to prevent soil erosion.
<h3>What is contour farming?</h3>
This is a soil conservation practice and to reduce erosion, it consists of arranging crop rows across the slope, following the contour lines.
Specifically, this practice helps to reduce water runoff and soil drag, since when planting the rows of crops against the slope, the other tasks of the crop, such as cleaning and hilling, are done in the same way and each furrow or row of the crop oppose the passage of rainwater that fails to filter into the soil, slowing down its speed, and thus there is less soil and nutrient runoff.
Therefore, we can conclude that according to the research, the correct option is contour farming. It is the agricultural technique which involves turning the soil over and parallel to the hill in order to prevent soil erosion.
