How does agriculture affect the environment?
While agricultural operations provide unique opportunities to conserve biodiversity, they also can threaten wild species and spaces. From habitat loss to pollution, agriculture contributes to many of the environmental challenges that WWF actively addresses.
How does farming affect the atmosphere?
Many farming practices—such as burning fields and using gasoline-powered machinery—are significant contributors to the buildup of greenhouse gases in the atmosphere. The Food and Agriculture Organization of the United Nations (FAO) contends that the livestock sector alone is responsible for 18% of all greenhouse gas production. Additionally, clearing land for agricultural production is a major contributor to climate change, as the carbon stored in intact forests is released when they are cut or burned.
Why is farming important?
Farming is the only viable livelihood option for three-quarters of the world’s extremely poor people. Subsidies provided by U.S. and European governments to their agriculturalists encourage overproduction, which drives down world prices and forces many producers in developing countries to cut corners environmentally. Producers facing declining harvests from cleared lands expand into surrounding wild lands that are rich in biodiversity, resulting in a cycle of increasing poverty and biodiversity loss.
What are the main sources of pollution in the world?
Agriculture is the leading source of pollution in many countries. Pesticides, fertilizers and other toxic farm chemicals can poison fresh water, marine ecosystems, air and soil. They also can remain in the environment for generations. Many pesticides are suspected of disrupting the hormonal systems of people and wildlife. Fertilizer run-off impacts waterways and coral reefs.
What is the effect of nitrogen on soil?
In addition, fertilizer application in soil leads to the formation and release of nitrous oxide, one of the most harmful greenhouse gases.
How do cattle damage soil?
Cattle and other large grazing animals can even damage soil by trampling on it. Bare, compacted land can bring about soil erosion and destruction of topsoil quality due to the runoff of nutrients. These and other impacts can destabilize a variety of fragile ecosystems and wildlife habitats. Chemical Fertilizer.
Where does nitrogen come from in fertilizer?
Roughly half the nitrogen in synthetic fertilizers escapes from the fields where it is applied, finding its way into the soil, air, water, and rainfall. After soil bacteria convert fertilizer nitrogen into nitrates, rainstorms or irrigation systems carry these toxins into groundwater and river systems.

Why has the forest area in the recent past not changed much?
5. The forest area in the recent past has not changed much because its diversion for non-forestry purposes has been more or less compensated by afforestation. “The annual withdrawal of fuel wood is estimated at 235 million cubic meters against a sustainable capacity of about 48 million cubic meters.
What are the by-products of burning rice?
The use of by-products such as paddy straw and rice husk has not been made properly. The burning of such by-products creates increase in carbon dioxide and carbon-monoxide in the atmosphere resulting in respiratory problems for animals and human beings . There is need for recycling the agricultural wastes by having enterprises like dairy, poultry, fishery etc., processing of by-products and ploughing in the field as organic matter.
Human expansion throughout the world caused that agriculture is a dominant form of land management globally. Human influence on the land is accelerating because of rapid population growth and increasing food requirements.
Land cover and land‐use patterns on Earth reflect the interaction of human activities and the natural environment [ 1 ]. Human population growth together with competitive land use causes land scarcity, conversion of wild lands to agriculture and other uses.
3. Results and discussion
With the growing world population the requirements are grown to cover the food demand. Human expansion throughout the world caused that agriculture is a dominant form of land management globally, and agricultural ecosystems cover nearly 40% of the terrestrial surface of the Earth.
