In 2011 alone, over 38.2 billion tonnes
of carbon dioxide was released into the atmosphere. Carbon dioxide is a
greenhouse gas. This means that it traps energy from the sun in our
atmosphere. As the levels go up the temperature goes up as well. If
we don't look at things like other animals and continental change
humans will still have somewhere between 8000 and 48000 years before the
levels of CO2 alone will be high enough to kill us. However not all
animals are as good at surviving in such conditions. Plus there are
other changes which would happen when the chemical ratio of in the
atmosphere changes. Currently the CO2 levels are
increasing by 2 parts per million a year. However if expansion continues
as it currently is, that could increase towards 10 ppm in as little as
100 years. This presents a huge problem. Since 2011 the levels have only
gone up. Yes some countries have lowered their emissions, but there are
others whose emissions have increased by larger amounts. Try and picture the amount of carbon which is not
filtered. Around 10 billion tonnes. That's the equivalent weight of
100'000 of the worlds largest class of aircraft carrier. It's insane.
And in total we're releasing four times that amount. To think that there
are 400'000 aircraft carriers worth of carbon (in weight) being thrown
into the atmosphere a year is astounding. Natural limits exist for
reasons. Breaking them by the amount we are is just not right. Increases
in temperatures isn't something that can change quickly. Should it get
to the point where temperatures are increasing dangerously, it will take
at least twice as long to set them back safely.
Amount Which Can Be Filtered.
Let's assume that all the trees in the world are Northern White Oaks. These trees are among the best at filtering carbon dioxide. In 2011 there were 9.88 billion acres of forest. So with these numbers around 29 billion tonnes can be filtered each year. Now that's all assuming that all the trees are Northern White Oak, and that the number of trees remains that same each year. Currently forests are being destroyed at a rate of 32123699.591 acres a year. That means that 80309249 fewer tonnes are filtered each year. That's if deforestation rates stay the same. Problems like this don't just go away. We need to protect the producers and remove our own impact on the environment. We don't have anywhere to go yet. So we need to ensure that our place is not destroyed.
