Cons of Industrial Agriculture.
It increases the risk of animal cruelty.
Conclusion.

How does agriculture affect wildlife?

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.

Why Agriculture is bad?

By radically changing the way we acquire our food, the development of agriculture has condemned us to live worse than ever before. Not only that, agriculture has led to the first significant instances of large-scale war, inequality, poverty, crime, famine and human induced climate change and mass extinction.

What can be said about farmers in highly developed countries?

higher crop yields. increased biological diversity of crops. reduced use of agricultural chemicals. O A Organic farming yields higher quality crops in larger amounts than conventional farming produces.

What are the major dangers to wildlife?

Wildlife is suffering Some of the biggest threats to wildlife include illegal wildlife trade, habitat destruction, invasive species, pollution, and clime change.

Why are wildlife important to humans?

When shown in a positive light, wild animals can inspire people to lead a sustainable lifestyle. They can invoke feelings of sympathy and compassion, causing people to be conscious of the damaging effects of their lifestyles. Wild animals provide a range of services to the human existence.

How does wildlife help the environment?

One compelling benefit that comes from wildlife conservation efforts is that it ensures food security. Protecting forests from deforestation and rebuilding forest habitats to preserve biodiversity aids in the carbon-sequestering process, provides new economic opportunities, and guards against erosion.

What will happen if we don’t protect wildlife?

The natural habitats of animals and plants are being destroyed for land development and farming by humans. The extinction of wildlife species will certainly have a fatal impact on human race as well.

How do humans affect animal population?

Human activity is by far the biggest cause of habitat loss. The loss of wetlands, plains, lakes, and other natural environments all destroy or degrade habitat, as do other human activities such as introducing invasive species, polluting, trading in wildlife, and engaging in wars.
