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.

How does rotational grazing affect biodiversity?
Through grazing for a limited time period in one area, biodiversity of native plants increases because grasses have time to regrow equally without one species taking over and becoming invasive.
Why do grasslands exist?
Grasslands provide habitat to a great number of animals and native plants. These areas have been almost entirely wiped out in other countries of Europe due to modern development or intensive agriculture.

What happens when soil is damaged?
When soil is damaged and water runoff occur s, that soil typically ends up in local water supplies. Farmers often combat damaged soil with synthetic fertilizers and other chemicals to increase crop yields. These activities contribute to the pollution of water supplies, which can further harm wildlife and even pose a risk to human populations.

Over time, these actions can cause strain on soil, local water supplies, and animal life.
Carbon Sequestration in Soils
Agriculture as Carbon Cap and Storage
Scaling up from soil to the entire industry, the agricultural sector could be “broadly carbon neutral” by 2030, effectively negating the agricultural industry’s humongous carbon footprint.
