give 3 reasons why our food supplies won't be sustainable in the future
Answers
They are essential to our survival as a species. However, numerous studies have shown that the food supply chain is jeopardising their functioning: it is a major cause of greenhouse gas emissions (GHG), unsustainable water extraction and pollution, deforestation and biodiversity loss.
Answer:
The climate, topography and soil variations within biomes may be challenging for growing food, but the way people change the environment can also have an impact on food production.
Explanation:
We have enough food for the roughly 7 billion people alive today, but nearly a billion are hungry or malnourished, mostly due to poverty and unequal distribution. To feed those who are currently hungry—and the additional 2 billion-plus people who will live on the planet by 2050—our best projections are that crop production will need to increase between 60 and 100 percent.
