they produce no CO2 so there good
Many things including good bacteria, oxygen, CO2, shelter, aesthetic improvement and much more. A plant in an aquarium environment does what a tree does in its land based environment.
Because the energy is not releasing harmful gases like co2 and methane into the enviroment.
yes
From plants when not receiving sunlight.
If you mean CO2--carbon dioxide--it is a natural part of Earth's environment. We can not breath it, but plants need it to survive. It can be used to extinguish fires. However, the increasing amount of CO2 in the admosphere (mostly from burning coal and petroleum products) is causing a problem of climate change.
It raises temperatures and adds CO2.
As CO2
yes as they do not give out carbon dioxide (co2) witch is contributing to the ice caps meltingYour answer is incomplete and barely right.Electric autos do not produce CO2 BUT to charge the battery CO2 is produced at the power generating plant!Every KwH used by an electric car generated on average about 600g of CO2.600g of CO2 is a worldwide average of CO2 emissions/ KwH.
The impact hybrid and electric cars will have on our environment is a very negative one. Just because they emit no or less Co2 doesn't make them good for the environment. Ask yourself, what is more harmful, emitting Co2 (Plant food) or using rare unsustainable minerals and metals for use in batteries? Not to mention you can use Co2 to grow plants for the use of food or biofuels.
The only thing that removes carbon dioxide (CO2) from the environment permanently is photosynthesis from growing vegetation. Trees remove CO2 and store it in their trunks, branches and leaves.
they release methane gas and co2
