Ans. Climate change can have several negative impacts on agriculture and food security. It can lead to changes in temperature and precipitation patterns, which can affect crop yields and quality. Extreme weather events, such as droughts, floods, and storms, can damage crops and reduce agricultural productivity. Climate change can also lead to the spread of pests and diseases, further impacting food production. Additionally, rising sea levels can contaminate freshwater sources and salinize agricultural lands, making them unsuitable for cultivation.
