A Quote by Wangari Maathai
The planet needs trees. If there is indeed that carbon dioxide out there in the atmosphere, the only species on the planet that can actually trap it for us in a natural process of photosynthesis are the trees.

When you buy carbon offsets, you pay to take planet-warming carbon dioxide out of the atmosphere in exchange for the greenhouse gases you put in. For example, you can put money toward replanting trees, which absorb carbon dioxide from the atmosphere.
We have an atmosphere that is roughly 21% oxygen. The rest of it is largely nitrogen. There's just enough carbon dioxide (CO2) to drive photosynthesis. That has been, throughout the history of our species, pretty stable. Until recently.
Carbon dioxide is natural. It occurs in Earth. It is a part of the regular lifecycle of Earth. In fact, life on planet Earth can’t even exist without carbon dioxide. So necessary is it to human life, to animal life, to plant life, to the oceans, to the vegetation that’s on the Earth, to the, to the fowl that - that flies in the air, we need to have carbon dioxide as part of the fundamental lifecycle of Earth.
So often we talk about saving the planet, but what we really mean is to save the planet the way it is, so we can live here. So that is can sustain us. Because the planet doesn't need to be saved. It doesn't care if all the squirrels, elephants, and trees die and there's just a couple of amoebas floating around at the poles.
Photosynthetic organisms in the sea yield most of the oxygen in the atmosphere, take up and store vast amounts of carbon dioxide, shape planetary chemistry, and hold the planet steady.
On the environmental front there's concern about global warming and high levels of carbon dioxide, and trees take in CO2 and store carbon.
By enriching the carbon-dioxide content of the atmosphere from its impoverished pre-industrial levels, human beings have increased the productivity of the entire biosphere - so much so that roughly one out of every seven living things on the planet owes its existence to the marvelous improvement in nature that humans have effected.
What a difference that extra 120 ppm has made for plants, and for animals and humans that depend on them. The more carbon dioxide there is in the atmosphere, the more it is absorbed by plants of every description - - and the faster and better they grow, even under adverse conditions like limited water, extremely hot air temperatures, or infestations of insects, weeds and other pests. As trees, grasses, algae and crops grow more rapidly and become healthier and more robust, animals and humans enjoy better nutrition on a planet that is greener and greener.
Natural gas emits only half the carbon dioxide of coal when burned, but if methane leaks when oil companies extract it from the ground in a sloppy manner - methane is far more potent a greenhouse gas than carbon dioxide - it can wipe out all the advantages of natural gas over coal.
It would be nice to find a 'planet of trees and birds' in the space; only trees and birds, millions of different trees and millions of different birds!
Ocean acidification is caused by the ocean absorbing excess carbon dioxide from the atmosphere, the same carbon dioxide that is the primary cause of global warming, hence the nickname 'the other carbon problem.' As they do so, the oceans become more acidic with terrible consequences.
The Arctic is a place that historically, during all preceding human history, has largely been an icy realm with an impact on ocean currents. That, in turn, influences the temperature of the planet. The Arctic is now vulnerable because of the excess carbon dioxide in the atmosphere, with a rate of melting that is stunning.
Burning fossil fuels emits carbon dioxide. And carbon dioxide is a greenhouse gas that traps heat in the atmosphere. There is no debate about that. The link is as certain as the link between smoking and cancer.
Here's the problem - carbon dioxide doesn't contribute to smog and isn't a health threat. All of this is being done because some people believe carbon dioxide is causing global warming, and that preventing carbon dioxide from entering the air is the only answer. Never mind that there is still an ongoing scientific debate about global warming itself, and that some respected climate scientists believe that methane is a better target, California legislators have locked their sites on carbon dioxide.
In his eyes shone the reflection of the most beautiful planet in the Universe---a planet that is not too hot and not too cold; that has liquid water on the surface and where the gravity is just right for human beings and the atmosphere is perfect for them to breathe; where there are mountains and deserts and oceans and islands and forests and trees and birds and plants and animals and insects and people---lots and lots of people. Where there is life. Some of it, possibly, intelligent.
We are putting value in the things that really are not valuable, things like commodities or disposable stuff that can bought, but the rainforest has been undervalued, because the value shouldn't be in the trees that you take out; it's should be with leaving the trees to preserve the life system that sustains life on the planet.
