Human Impact on the Environment and Information Technology
1. Humanity and Pollution
The term “pollution” is related to humanity’s ability to alter the environment beyond basic survival needs, unlike other animal species. Humans have always interacted with nature for survival, which involves modifying the natural environment. The pollution problem has existed since the beginning because life itself generates waste. When nomadic populations transitioned to farming, they tilled the soil, irrigated dry land by diverting water flow, and cut down forests to build

Agriculture
The main problems in agriculture are overexploitation of soil and rising food prices, which hinder access to food in poor countries.
Another feature of current agricultural expansion is the use of GMOs. This involves transferring genetic material (a DNA fragment) from one species to another to introduce or eliminate a specific gene responsible for a desired trait.
Types of Agriculture in the World
- Traditional or Subsistence: Practiced on 75% of the world’

Volcanic Eruptions
Nonexplosive eruptions are relatively calm outpourings of lava that can release a huge amount of molten rock. Explosive eruptions release clouds of hot debris and gases, often at supersonic speeds.
Volcano Formation
Volcanoes form around vents that release magma onto Earth’s surface. The composition of magma determines if a volcanic eruption is explosive, nonexplosive, or somewhere in between. High water and silica content in magma increases the likelihood of an explosive eruption.
