a. in image 1 it is land pollution and in image 2 it is air pollution caused by the factories
Explanation:
a. land pollution and air pollution are the major causes for global warming. as the harmful gases are released from the factories such as chlorofluorocarbons, methane, carbon dioxide and carbon monoxide in a large volume. these gases have the tendency to trap the heat energy released from the sun and make the earth warmer than it should be in normal. coming towards the land pollution, lack of waste management causes unhygienic environment and destroys the soil fertility. as it causes unhygienic environment, risk of many harmful diseases increases such as bacterial infections, fungal infections, mosquito causing diseases like dangue, malaria, etc. also it pollutes the soil and the air and makes the soil unsuitable for the planting.
