Global Warming --C02 use in greenhouses Question?

Question

It is a fact that many commercial greenhouses supply extra co2 to promote plant growth. If there is extra c02 around why don't we see a surge of plant growth on the planet?

Answer 1

You first need to understand how GreenHouses work..

A greenhouse is a structure with a glass or plastic roof and frequently glass or plastic walls; it heats up because incoming solar radiation from the sun warms plants, soil, and other things inside the building. Air warmed by the heat from hot interior surfaces is retained in the building by the roof and wall. These structures range in size from small sheds to very large buildings.

The glass used for a greenhouse works as a selective transmission medium for different spectral frequencies, and its effect is to trap energy within the greenhouse, which heats both the plants and the ground inside it. This warms the air near the ground, and this air is prevented from rising and flowing away, in addition to the fact that infrared radiation cannot pass through the greenhouse glass. This can be demonstrated by opening a small window near the roof of a greenhouse: the temperature drops considerably. This principle is the basis of the autovent automatic cooling system. Greenhouses thus work by trapping electromagnetic radiation and preventing convection. Miniature greenhouses are known as a cold frame.


Just increased CO2 in the atmosphere is not enough for plants to grow .. They need sunlight , in night time , plants cant breather CO2 , instead they give out CO2.. ...

and you need to plant trees if u want to see its surge, all we do is cut them down , so no matter wht conditions prevail, plants wont last long ..

Answer 2

There's a limit as to how much CO2 a plant can utilise - just as there's alimit to the amount of oxygen a human can breath. If there's more than is needed then there's an unused surplus.

In nature there's an unused surplus of CO2 - the plants already have more than they need. To naturally remove some of this surplus would involve planting more trees and plants - a step that many people are taking in order to offset their personal carbon footprint.

Answer 3

Some places will have a surge in plant growth, but not over the whole planet. The CO2 produced by commercial greenhouses will not make a big enough difference.

Answer 4

Because C02 is not the evil global warming gas that it is made out to be.

Answer 5

first not all plants grow better with additional CO2 and while the CO2 helps them the increased temperatures, and water shortage will limit thier growth, you have to look at the big picture not just a small part, also CO2 would not creat a "surge" in plant growth, it would increase it but not by a massive amount that would be obvious

Answer 6

We DO... but you don't 'cause you live in an apartment. I live in a house, and I see it and cut it EVERY weekend.

Answer 7

there are many other factors to consider such ar sun light other plants in the area what they are grown for and many other things

Answer 8

because we keep bulldozing forests
