Write a speech on Topic-Humans are to blame for environmental degradation.
Answers
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
The majority of air pollution is the result of human activities. For example, increased fossil fuel combustion from motor vehicles, industrial factories and power plants all pump large quantities of air pollutants, such as carbon monoxide, ozone and nitrous oxides, into the atmosphere.
Deforestation and the conversion of wild spaces for human food production have largely been blamed for the destruction of Earth's web of life. The report highlights that 75% of the Earth's ice-free land has been significantly altered by human activity, and almost 90% of global wetlands have been lost since 1700.
