Other effect of deforestation in the Amazon rainforest is seen through the greater amount of carbon dioxide emission. The Amazon rainforest absorbs one-fourth of the carbon dioxide emissions on Earth, however, the amount of CO 2 absorbed today decreases by 30% than it was in the 1990s due to deforestation. [35]
In the 19th century, the introduction of steamboats in the United States was the cause of deforestation of banks of major rivers, such as the Mississippi River, with increased and more severe flooding one of the environmental results. The steamboat crews cut wood daily from the riverbanks to fuel the steam engines.
The main cause of deforestation in the East African country of Ethiopia is a growing population and subsequent higher demand for agriculture, livestock production, and biofuel. [22] Other reasons include low education and inactivity from the government, [23] although the current government has taken some steps to tackle deforestation. [24]
The direct cause of most deforestation is agriculture by far. [33] More than 80% of deforestation was attributed to agriculture in 2018. [34] Forests are being converted to plantations for coffee, palm oil, rubber and various other popular products. [35] Livestock grazing also drives deforestation.
This is close to the observed overall warming during that time of 0.9 °C to 1.2 °C. Temperature changes during that time were likely only ±0.1 °C due to natural forcings and ±0.2 °C due to variability in the climate. [31]: 3, 443 Global anthropogenic greenhouse gas emissions in 2019 were equivalent to 59 billion tonnes of CO 2.
The proximate causes were clustered into broad categories of agricultural expansion (96%), infrastructure expansion (72%), and wood extraction (67%). Therefore, according to this study, forest conversion to agriculture is the main land use change responsible for tropical deforestation.
This eliminates or reduces many of agriculture's environmental issues, such as deforestation, large quantities of greenhouse gas emissions, and reliance on extreme amounts of food and water.
