in what ways are plants useful to us especially in pollution?
Answers
Green environment can provide the cleanest and safest place for humans to live. Trees and plants are oxygen generating factories that cleanse air, absorb carbon dioxide and supply oxygen for animals and humans to breathe. Deforestation and urbanization have left us with lesser number of plants to combat the air pollution around us. While increasing rate of air pollution poses serious health risks for humans, these outdoor plants can help beat the detrimental effects of air pollution and purify the air around us to a great extent.

Answer:
(1) Plants transform light into energy that other organisms can use! This includes food—for example, sea turtles and manatees eat sea grasses, and people and livestock eat plants—and the natural gas/oil/coal/firewood that we can use to fuel fires and to generate electricity. They also sequester CO2—an important greenhouse gas—by using the carbon as an important material for growth.
(2) Plants provide a habitat for all sorts of creatures, including humans, other plants, and microbes—for example, nitrifying bacteria which is a very important microbe that live at plant roots turns gaseous nitrogen into a form that plants can assimilate. An area with lots of plants is sure to have a lot of other organisms in and nearby as well!
(3) Plants improve resilience and protect health: mangrove forests protect coastlines from erosion and storm surges; the roots of plants stabilize the ground and help retain water in the soil so that watersheds will be healthy and ensure the supply of groundwater and water to rivers and lakes; we get many of our medicines and supplements from plants; green spaces in urban areas make for cleaner air and cooler, more relaxing surroundings for stressed city people.
(4) Plants support the economic and political environments too—natural resources, of which plants are key, are the foundation of economic growth and drive political agenda
(5) Plants play an important role in influencing the climate: globally, in how it sequesters carbon and also releases CO2 when plants are burned as fossil fuels; and locally, in how it influences the micro-climate of a region, especially through evapotranspiration that increases humidity (because of water evaporating from leaves) and with how plants use sunlight, absorbing the heat and reflecting the sun’s rays away (albedo effect).
