One of the most obvious consequences is the depletion of aquifers, river systems, and downstream ground water. However, there are a number of other negative effects related to irrigation.


What are the environmental concerns of agriculture?

One of the primary environmental concerns with modern agriculture has to do with the chemicals we put on crops and what happens when those crops end up in the watershed. Pesticides and other chemicals are often used to produce more crops, and these pesticides don’t just fall on the crops and stay there: they are transported via wind and water …


What happens when we clear land for agriculture?

Forests, grasslands, and other ecosystems are converted for farmland. When we clear land for agriculture, we often lose some soil.


What is the result of eutrophication?

The result may be eutrophication, an excessive amount of nutrients in a body of water resulting in a substantial growth of plants, such as algae, and a lack of oxygen in the water because of this increase in plants.

Why is the pH of soil changing?

Bacteria in the soil tend to decay the waste and enhance soil fertility. But when the pH is changed, they are unable to survive; this leads to the destruction of environmental diversity and balance.


Feed Production

As the number of farm animals in the U.S. increases, feed production also rises to sustain their diet. These species are herbivores and consume high amounts of grain. Rice, wheat, and other grains are water-intensive crops. It takes 4,000 liters of water to produce a kilo of rice, contributing to the environmental impact of animal agriculture.


Methane Emissions

The production of cattle releases a toxic greenhouse gas, which is one of the driving elements of climate change. Methane is emitted into the atmosphere when cows produce gas. In the atmosphere, it contributes to the enhanced greenhouse effect.


Grazing Land

As our demand for chicken sandwiches and hamburgers increases, farmland must expand. The overproduction of cattle in the Amazon is the number one driver of deforestation. Animal farming accounts for 80% of all current deforestation.


Transportation

Factory farms contain many more animals than traditional farms in small, confined spaces. An increase in animals raises urine and feces production, which farmers disperse throughout the land to limit the soil’s immediate impacts. Farms collect the secretion, mix it with water, and spray it across their property.


How to Limit Your Impact

There are various methods for reducing your diet’s environmental impact. To limit the greenhouse gas emissions associated with factory-farmed meat transportation, you can consume locally grown animal products. Buying directly from a local farm or butcher significantly reduces the carbon footprint of meat.
