What are two major challenges resulting from the increasing global population

Lack of resources and negative impact on the Earth.

Explanation:

Increasing global population results in increased consumption of resources such as land, food, water, air, fossil fuels and minerals, and consequently, increased waste products as a result of consumption such as air and water pollutants, toxic materials and greenhouse gases.

Many people worry that unchecked population growth will eventually cause an environmental catastrophe. This is an understandable fear, and a quick look at the circumstantial evidence certainly shows that as our population has increased, the health of our environment has decreased. 

Additionally, as the world population continues to grow, the limits of essential global resources such as potable water, fertile land, forests and fisheries are becoming more obvious. On the whole, more people use more resources and create more waste.

Hope this helps!
