Think of as many you can in which human activities are affecting the environment. Start off by listing them, but then try and put them into a spider diagrem with lines pointing to the different kinds of effects, such as: global warning, habitat destruction, killing of whildlife, etc.

describe how humans may exercise choices which could limit or worsen the effect of the environmental damage that they cause.

There are many human activities affecting the environment. Between them, we can find:

Deforestation: The human actions of destroying forests, usually to switch the land to agriculture and rural areas, or to explore the resources in the forests for economical purposes.

Consquences: Increase in carbon dioxide in the atmosphere, due to the decrase in the capacity of holding carbon dioxide that the forests do naturally, and also by the amount of carbon dioxide being release into the nature throughout the process of deforestation, such as fires. It helps with global warming, and also threatnes the species that have forests as their natural habitat. 

Bad use of water: Water is already known to be scarce for more than 500 million people, and by 2025 3.4 billion people will be living in areas prone to droughts. Water is being unsustainably wasted for irrigation purposes.

Consequences: The lack of water can lead to a decrease in food and economical production, as well as conflict over resources. 

Consumption levels: If everyone consumed as much as Americans, we would need 5 Earths. The consumption rates are increasing globally, as well as an increase in the amount of people consuming these goods. World population increased from 2 billion people in 1930 to more than 7 billion people right now, and it is predict to reach 9 billion people in less than 20 years. The increase alone is more than the total population level in 1930. The increase in population (demand) combined with the increase in production (supply) is leading to deforestation and resources scarcity, as well as polluting that come from cars, factories and instense use of oil.

Consequences: Resource scarcity, global warming due to increase in polluting gases, and climate change that affects the intensity of storms and increases the average global temperature, leading to fatal consequences if not reverted in time. 

agriculture ---->       Deforestation ----------->  increase in carbion dioxide -----> Climate change

rural areas ---->      Deforestation ---------> threatning of species ------> Climate change

unsustainability  -----> resource scarcity -----> conflict

scarcity----->            Bad Use of Resources ---> Climate change

increase in population ---->

increase in consumption ------>  Consumption levels ---------->Climate change

There are many human activities affecting the environment. These are as follows: Deforestation: Destruction of biotic potential of land leads to desertification. Such problem arises due to over-grazing, indiscriminate felling of trees and over-exploitation of land resources. Desertification: Desertification is the process leading to desert formation. This may result either due to a natural phenomenon linked to climate change or due to abusive land use. Global warming: Due to green house effect, there may occur more hurricances and cyclones and early snow melts in mountains causing more floods during monsoon. Killing of wild life: Poaching for meat, skin, fur ,ivory, rhino horns etc. Destruction of their natural habitats due to expanding agriculture urbanisation and industrialisation. Deforestration---------soil, water and wind erosion------climate change Desertification---------forest diminishes-------climate change Global warming---------carbon di oxide increases------climate change Killing of wild life--------------climate change
