BBC Crops Source

This source focuses on how food shortage will affect people all over the world. A recent study suggested that "southern Africa could lose more than 30% of its main crop, maize, by 2030." Also, "The effects in these two regions could be catastrophic without effective measures to adapt to climate change." This is very important: adaptation. This is inevitable in our future. This quote shows how climate change doesn't have to overpower us: we can adapt to our new environment, change our behavior, and fix our climate. Water shortage, life, and crops can be saved with the proper action. We just need leaders who are willing to act. Once high-powered leaders become involved in the fight against global warming, others will follow. Therefore, people will act because of indirect reasons: the crops, water, and life are at risk. Politicians and activists become environmental leaders. The rest of the world follows. This thought process is the most important part of my answer so far.
The rest of this article is about how farmers will lose sorely needed money, and the agriculture society will fall apart, if crops continue to fail due to global warming. These effects will be felt all around the world. It is just one more reason why we need to act now.
