Shortages of Food and Water

Climate change is responsible for the increasing shortages of food and water around the world.

The planet which we live in must remain healthy in order for us to live here and must be able to provide all of the necessary resources for living.

Due to our greenhouse gas emissions, the entire biosphere is in disequilibrium and this is affecting food and water supplies on a global scale.

Climate change will worsen the world's shortages of food and water

Increasing Food Shortages

World starvation is already a drastic problem across the world.

In fact, the World Health Organization reports that hunger is the greatest threat to the world's public health, and that undernourishment is the biggest contributor to child mortality, responsible for half of all cases.

Every year, over 2.6 million children die from starvation and about 925 million people, roughly 13.5% of the world population, are undernourished.

This problem will be only compounded by climate change since agriculture will be gravely affected.

Moreover, rising prices and the lack of crop production means less and less people will have access to food over time.

Decreased Crop Yields and Rising Food Prices

Rising temperatures across the globe means that people in every single country will not be able to produce as much crops.

This means that they will have to raise prices in order to make the same profits which they were making before.

Many people who are already starving across the world will find it harder and harder to get food, as they will be paying more money for less food.

The rising temperatures combined with disasters and less rainfall in recent years means that the food harvest is drastically less and the world starvation problem is drastically greater.

According to the New York Times, “Many of the failed harvests of the past decade were a consequence of weather disasters, like floods in the United States, drought in Australia and blistering heat waves in Europe and Russia.”

Furthermore, desertification will decrease the amount of arable land and rising sea levels will threaten land suitable for agriculture.

Water Shortages

Water, the most fundamental nutrient needed to live, could be affected by climate change. 

Glaciers and ice caps account for nearly 70% of the world's freshwater and and are melting rapidly.

Many perennial rivers flow from glaciers and many farmlands depend on them. As a matter of fact, over 1 billion people will face water shortages if the Himalayas melt.

In certain regions, less and less rainfall each year means not only that crop harvests will be down but water supplies will decrease well.

Getting clean water is already a problem in so many countries that shortages of water would cause dire consequences.

Besides, rising sea levels could increase water shortages even more as they will salinate fresh water supplies.

Growing World Population

The increasing population growth across the world means more and more people will consume water, but may find it hard to come by.

In 2050, the human population may hit 9 billion and this will only aggravate the current situation.

ACS’s Journal of Environmental Science and Technology reported that more than 1 in 3 counties in the United States could face a high or extreme risk of water shortages by the middle of the 21st century.

ScienceDaily explains that the Sujoy B. Roy, Ph.D., and his associates figured this out by using a “water supply sustainability risk index” that considers water withdrawal, projected growth, possibility of drought, projected climate change, and other factors.

Lack of Media Attention

Although little attention has been paid to shortages of food and water, they are just as important (or even more so) than rising sea levels.

If we do not make a serious effort to stop climate change, these shortages of food and water will only amplify in the future.
