How does deforestation cause land pollution?

Answer 1

Trees, and indeed all plant life, consume carbon dioxide (CO2) through the chemical process known as photosynthesis, which converts carbon dioxide into organic compounds using energy from sunlight and producing oxygen as a by-product. Humans and animals consume oxygen and produce CO2, as a by-product, as do many industrial processes. Forests of all types, rain forests, evergreen forests, etc., are especially efficient at this vital function (reprocessing CO2). They also provide shelter and sustenance for a great number and variety of plants, insects and animals which are also vital for the natural food chain, each species depending on the next or the former in the chain to exist. Many of these inhabitants are, as yet, undiscovered, and so, their vital and necessary function and possible use in the creation of medicines and other useful products aren't yet known.

Deforestation removes the most efficient "air scrubbers" and oxygen producers on our planet, as well as, the forest inhabitants and their potential usefulness to humans. Also, many times forests are removed, not simply for the lumber but, as a means of creating arable land for farming by burning thereby producing a great deal of carbon pollution. What is not taken into account is that the soil of forests are often only able to sustain a farm for a few growing seasons since what made the topsoil nutrient rich was the trees, insects and animals that have been removed and/or displaced by clearing the forest. The planet loses the value of the forests for CO2 removal and oxygen production and the farmer cannot survive very long on the land that was cleared by creating a great deal of pollution.

Answer 2

As we inhale oxygen and exhale carbon dioxide plants e.g. trees inhale corbon dioxide and exhale oxygen through their leaves but if the number of plants/trees decrease the rate of carbon dioxide emitions will go up because there are less plants to 'recycle' it.

Answer 3

Deforestation cause l;and pollution because when we cut don the trees, the soil will become loose and soil erosion will take place.
