“Less biodiversity means that plants and animals are more vulnerable to pests and diseases. Compounded by our reliance on fewer and fewer species to feed ourselves, the increasing loss of biodiversity for food and agriculture puts food security and nutrition at risk,” added Graziano da Silva.

loss of wildlife habitat and crop depredations were the major concerns. The major negative impacts include loss or alteration of habitat, wildlife depredation on crops or livestock, trans mission of disease between livestock and wildlife, competition for range land, and access problems for wildlife users.

According to some estimates, industrialized farming–which produces greenhouse gas emission, pollutes air and water, and destroys wildlife–costs the environment the equivalent of about US$3 trillion every year.

Many critical environmental issues are tied to agriculture, such as climate change, dead zones, genetic engineering, pollutants, deforestation, soil degradation, waste, and many others. Deforestation is a big side effect of agriculture that greatly impacts our planet and the environment.

The top fertile soil of the farmland is removed due to the excessive water supply. This leads to the loss of nutrient-rich soil that hampered productivity. It also causes global warming because the silt of water bodies induces the release of soil carbon from the particulate organic material.

Excessive water-supply and wind removes the top fertile layer of the farm. Loss of nutrient rich soil not only reduces productivity, but also results in silting of water bodies and streams and induces release of soil carbon from particulate organic material, which contributes to global warming.

Livestock farming has a vast environmental footprint. It contributes to land and water degradation, biodiversity loss, acid rain, coral reef degeneration and deforestation. Nowhere is this impact more apparent than climate change – livestock farming contributes 18% of human produced greenhouse gas emissions worldwide.

When it comes to climate change, animal agriculture is a leading culprit. Those crops and water are used to bulk up animals for slaughter. The animals emit noxious levels of CO2, methane gas, and excrement that pollute our air and waterways.

Animal agriculture is the second largest contributor to human-made greenhouse gas (GHG) emissions after fossil fuels and is a leading cause of deforestation, water and air pollution and biodiversity loss. …

According to a 2006 report by the Food and Agriculture Organization (FAO) of the United Nations, the animal agriculture sector emits 18% of global, human-induced greenhouse gas emissions.

Human activity is the main cause of climate change. People burn fossil fuels and convert land from forests to agriculture. Burning fossil fuels produces carbon dioxide, a greenhouse gas. It is called a greenhouse gas because it produces a “greenhouse effect”.

Raising and killing animals for food is cruel and so reduces the total amount of goodness in the world. If everyone was a vegetarian, there would be no demand for meat. If there were no demand for meat no one would raise and kill animals for food. Therefore everyone should be a vegetarian.
