Can we increase agricultural production without threatening biodiversity?

The world population is expected to reach 9.8 billion by 2050. This increase in population will put pressure on agriculture to produce more food. Many studies have reported that land-use changes, such as cutting down forest to make new farmland, can lead to a loss in the number of species living in an area, known as the biodiversity. It is important to maintain biodiversity because it supports healthy ecosystems and ultimately a healthy planet. A recent analysis of previously published scientific articles suggests that when farming efforts are intensified, agricultural production increases but the number of species supported by the farm decrease. This means that increasing agricultural production comes at a cost.

How air pollutants hurt wheat

Air pollutants like ozone can cause damage to plants. Wheat currently provides 20% of dietary protein and caloric intake for the world’s growing population. A recent analysis led by Gina Mills and scientists from across the globe reports that increased levels of ozone will decrease global production of wheat by 85 million tons. Furthermore, the negative effects of ozone may counteract the positive effects of irrigation in wheat fields.
