burning of forests also produces carbon dioxide which affect the carbon cycle

Answer 2

Answer:

• Human activities can affect the carbon cycle by burning fossil fuels, changing land use, and using limestone to make concrete all release significant quantities of carbon into the atmosphere.
• Due to this, the amount of carbon dioxide is rapidly rising in the atmosphere.
• It is already higher than at any time in the last 3.6 million years.
• The ocean absorbs carbon dioxide that is released from burning fossil fuels.
• This extra carbon dioxide lowers the ocean’s pH, through a process called ocean acidification.
• This in turn interferes with the ability of marine organisms to build their shells and skeletons.
