There are many human activities that can affect the biosphere. Few examples of these activities include hunting and gathering, industry, and agriculture. All of which have benefits and costs.

Hunting and gathering has the benefit of providing food and supplies for human populations. However, it may have the cost of potentially making a species go extinct due to overharvesting.

Industry provides human populations with technology and other convenient items. However, it may come with a cost of producing pollution such as due to the burning of fossil fuels.

Lastly, agriculture can provide human populations with a supply of food. However, it may also come with a cost of environmental harm due to the release of chemicals such as pesticides.

Humans and other organisms depend on a breathable air, drinkable water, and the recycling of nutrients for the long-term survival of their species.

Agriculture provided enough food to supply a large amount of humans over an extended period of time. Agriculture basically allowed humans to utilize energy from the sun through photosynthesis to power their survival. This allowed humans to start civilizations and not have to move around as nomads anymore. Humans can stay in one place and not look around for food anymore.

The industrial revolution has made the process of production much easier. This has raised the standard of living for most humans and have made products available to a wider selection of customers.

Another way it has affected earth is that it released a great deal of pollution into the air and significantly contaminated the atmosphere. This has already caused certain species of organisms to become extinct.

The increase in the productive agriculture practices would result in the elevation of the rate of growth of population since there will be more resources available. However, it would also incur negative effects on the environmental health of the nation
