Why is land scarce?
Land is another resource that is becoming increasingly scarce and putting a strain on the agricultural industry. As the population grows, there are a number of reasons why land availability is negatively impacted, foremostly a result of the fight for industrialization, urbanization, and housing versus agricultural growth. While some argue that increased urbanization poses a threat to agricultural growth, some studies indicate that the threat is a bit more complex.#N#At a glance, urbanization is usually considered a threat to agricultural growth: as urban expansion increases at the expense of agricultural land, we generally see a loss of physical resources when it comes to agricultural growth.

The Making of a Dead Zone
First, let’s delve into the science behind dead zones to understand how and why they actually occur. Eutrophication happens when excess nutrients enter a waterway—be it stream, river, or ocean. Too much of a good thing results in a lot of very bad things. Extra nitrogen and phosphorous encourage algae growth which results in algal blooms.
Where in the World?
Dead zones can be observed anywhere that excess nutrients accumulate and algae can bloom. However, there are a few notable areas where devastation is well known and widespread.
The Animal Agriculture Tie-In

How does agriculture affect the environment?
Agriculture relies on natural processes and living things to create food, but often changes the environment around it. While farms can be managed in ways that minimize their damage to the environment around them, industrial agriculture’s focus on productivity means that too many farms are disruptive to wild species both near and far. When environments are too altered or polluted by industrialized agriculture, vulnerable species may lose their habitats and even go extinct, harming biodiversity.
Why is industrial agriculture important?
Unfortunately, industrial agriculture prioritizes consistency and productivity over biodiversity, and relies on only a few varieties of plants and animals .
What are the innovations that helped farmers produce more food per acre?
Widespread adoption of steel plows, hybrid seeds, GMOs, chemical fertilizers and pesticides helped farmers produce more food per acre than ever before. More recently, the adoption of genetically modified seeds helped to increase yields even further. This productivity comes at a great cost, however. Wide fields of a single crop (called monocultures) provide simplicity for farmers and a steady supply of feed to factory farms, but they are biodiversity deserts. Maintaining monocultures requires intense chemical inputs that reduce the abundance of wild species both on and off the farm.
