The document discusses several potential global disasters and sustainability issues if actions are not taken, including: 1) Effects of climate change such as rising sea levels, stronger storms, droughts and floods could displace millions and endanger food security. 2) Many youth face risk of poverty in old age due to spending habits and debt, lack of financial education, unemployment and need for family planning and youth incentives. 3) Food shortages may occur due to smaller farm plots, high population growth outpacing food production, and climate change effects, raising food prices beyond many people's means. 4) Unregulated competition could lead to business collapses and loss of investments impacting people's mental health.
