increase the amount of photosynthesis

deforestation has no impact on the carbon cycle

Detailed explanation-1: -Trees and other plants absorb carbon dioxide from the atmosphere as they grow. This is converted into carbon and stored in the plant’s branches, leaves, trunks, roots and in the soil. When forests are cleared or burnt, stored carbon is released into the atmosphere, mainly as carbon dioxide.
Detailed explanation-2: -Deforestation facilitates one part of the carbon cycle, increasing the CO2 in the atmosphere. It also prevents forests from absorbing any further carbon by destroying the trees. It, therefore, inhibits this aspect of the cycle and leads to increased levels of this greenhouse gas in the atmosphere.
Detailed explanation-3: -When trees are cut down there are less plants to absorb carbon dioxide for photosynthesis. More carbon dioxide stays in the atmosphere if there are less trees, therefore, increasing the amount of greenhouse gases which trap heat in the atmosphere and warm the Earth.
Detailed explanation-4: -Burning fossil fuels, releasing chemicals into the atmosphere, reducing the amount of forest cover, and the rapid expansion of farming, development, and industrial activities are releasing carbon dioxide into the atmosphere and changing the balance of the climate system.
Detailed explanation-5: -Trees absorb and store carbon dioxide. If forests are cleared, or even disturbed, they release carbon dioxide and other greenhouse gases. Forest loss and damage is the cause of around 10% of global warming. There’s simply no way we can fight the climate crisis if we don’t stop deforestation.
