what are some negative effects of using crop residues for energy production?
605383
Removal of more than 50% of crop residue can have negative consequences for soil structure, reduce soil organic carbon sequestration, increase water erosion, and reduce nutrient cycling and crop production, particularly in erodible and sloping soils.

Disadvantage: Unwanted Side Effects Power plants that burn fossil fuel pump carbon dioxide into the atmosphere. Carbon dioxide is a greenhouse gas that causes Earth's temperature to rise. Nuclear power plants must find ways to dispose of radioactive waste safely.

Synthetic fertilizers have long-term negative effects. Synthetic fertilizers kill beneficial microorganisms in the soil that convert dead human and plant remains into nutrient-rich organic matter. ... Synthetic fertilizers damage the natural makeup of soil in the long term.

The same chemistry that enables coal to produce energy—the breaking down of carbon molecules—also produces a number of profoundly harmful environmental impacts and pollutants that harm public health. Air pollution and global warming are two of the most serious.

Global warming could lead to an increase in pest insect populations, harming yields of staple crops like wheat, soybeans, and corn. While warmer temperatures create longer growing seasons, and faster growth rates for plants, it also increases the metabolic rate and number of breeding cycles of insect populations.

Disadvantages of Oil Energy This has been the biggest threat to using oil energy. After combustion, oil releases gases such as carbon dioxide and other greenhouse emissions. These gases are very harmful to the ozone layer as their accumulation encourages its deterioration.

Biotech crops have contributed to significantly reducing the amount of greenhouse gas emissions from agricultural practices. This results from less fuel use and additional soil carbon storage from reduced tillage with biotech crops.

Crops do not damage the environment simply because they are GM. Some farming practices, such as the overuse of herbicides resulting in the excessive eradication of wild plants from farmland have been shown to harm the environment. These problems are similar for non-GM and GM crops.

In short, raw material extraction and processing always impact on the environment, resulting as they do in soil degradation, water shortages, biodiversity loss, damage to ecosystem functions and global warming exacerbation. And that's not all.

Crop Production Fresh fruits and vegetables come in contact with water during various stages of the production process. Contaminated water that is used during crop production, harvesting, and processing can lead to health issues. Crops with contaminated water used for pesticide or herbicide application.

Here are the main facts why palm oil plantations are harming the environment: They release massive amounts of CO2 in the air as rainforests are cleared. Rainforests' soils hold about 45% of the world's terrestrial carbon, cutting them down is like releasing a carbon bomb.

Using Wood to provide heat and electricity has advantages that include: potentially renewable forest and can be local, and Disadvantages that include increased deforestation, not enough, and air pollution. Plant materials and animal wastes can be converted into gaseous or liquid biofuels.

Food waste has significant implications that directly impact society on a number of levels. It has direct impacts on the environment and contributes to climate change; wastes economic capital and the finite resources used in food production; and, finally, it increases global food insecurity.

While negative impacts are serious, and can include pollution and degradation of soil, water, and air, agriculture can also positively impact the environment, for instance by trapping greenhouse gases within crops and soils, or mitigating flood risks through the adoption of certain farming practices.

Conclusion: There are both positive and negative impacts of Green Revolution on farmers. Due to Green Revolution there was the considerable increase in the food grains production which was extremely necessary for a farmers to increase production so that agriculture become remunerative.
