This is my view of how climate change will affect wildlife - Maina
When world leaders discuss climate change, the picture that is in their minds is of people caught in drought and floods, melting snow and icecaps in the mountain ranges and polar regions, and the polar bear. Well, that is not the worst case scenario. Less obvious wildlife (as compared to the polar bear) will suffer too – and perhaps more than humans.
You see human kind – as a species – will survive this rapid change in climate better than wildlife. Humans, in short, will survive. But some non-human inhabitants of mother Earth will not. It’s a given that wild species of animals and plants survived the beginning and end of the Ice Age, but they did so naturally. The climate change then was not as rapid as the climate change we are witnessing today. We all know the reason why – humans had not invented the steam engine, hadn’t discovered coal and petroleum and industrialisation was not even a seed in the little mind our ancient ancestors.
Now greenhouse gas emissions and an opulent consumerism has renderd the natural systems weak and the pace at which global warming and other climate change factors are progressing is mind boggling – and wildlife cannot keep abreast.
Take the example of trees. In mountain ranges, there is a nice tiered arrangement of different dominant species of plants. From lowland forest trees to upland, bamboo, alpine glades, tundra etc. Two problems arise here. 1) Assuming the vegetation belts can quickly stay at pace with temperature rise, they will push each other up the mountain until they all have nowhere else to go then they go extinct. 2) In reality, they cannot keep up the pace so they will die on the way up.
The great Savannahs of Africa may look indestructible – but they are not. We are increasingly seeing irregular rain patterns which is disrupting vegetation growth resulting in mass deaths of the massive herds of charismatic and much loved large herbivores, and their attending predators iconically represented by lions, cheetah, leopard and the like.
In Kenya recently, prolonged drought – and we can not rule out the effects of climate change as the cause – first killed livestock, then pushed the livestock into wildlife habitats, then killed the wildlife. Now Kenya is – ironically – waiting for El Nino rains to settle in so that it can save people, their livestock and wildlife. But the El Nino could be made more severe by the effects of climate change. So more people, livestock and wildlife will die. Iregi Mwenja, a Kenyan bushmeat researcher posted pictures of the onset of the El Nino rains in Voi today. One of the casualties of the big water was a masai goat that died in the floods.
That is a look on the extreme weather conditions that climate change is making worse. The silent increase in temperature will have the most devastating impact on wildlife as habitats change. According to the BBC:
It is estimated 20-30% of plant and animal species will be at increased extinction if the temperature rises by more than 1.5 – 2.5C. Less snow in winter, warmer temperatures in summer and more winter rain will affect wildlife across the board. Sea level rises will reduce land area in some countries, which will instantly affect vegetation which is currently used for homes and foods by animals.
In Africa, most of traditional dispersal area for wildlife is now occupied by humans as population increases exponentially. When climate change takes full effect, wildlife will attempt to move to these areas and human-wildlife conflict will escallate. The result is that wildlife will be killed. From another perspective, humans, with the effects of climate change on their heels, will invade wildlife protection areas, killing wildlife to create room for themselves, and their ravenous progeny.
Lest you tell me that the earth is man’s home, and we don’t need the wildlife, let me remind you the intricate balance between biological systems, including bacteria! and the physical (rock) earth. The scientific author, Edward O Wilson, in his book “The Future of Life” talks of the earths biological system as a layer of living matter so thin you cannot see it sideways from space but absolutely neccessary for overall integrity of the planet as a whole (including energy flows). So there you have it: Without the biological system, there is no earth. Or in a language that you will understand, without the biological matter of old that became fossilized millenia ago, we would not have oil or coal = no fuel = no cars = no industrialization.
It is time to act. Our first wave of action is no doubt massive adjustment to our consumption patterns in order to reduce greenhouse gas emissions. This, if dully practiced, could slow down climate change. Talk, write, chant, wave placards at or do what you do best, but make your leader act on climate change. Tell them that when they get to Copenhagen on 7-18 December 2009, they have to come up with a climate deal that saves us and wildlife. And go over to TckTckTck and join the more than 2 million ‘planet earthians’ tell the world leaders that you are ready for a climate deal that works.
It is said that climate change is inevitable, but the pace will have to slow down. Climate change has occurred before, but not at this pace. Let us all change the way we live, slow climate change and give the other inhabitants of this planet a chance to take on climate change at their own pace. We cannot make them adapt at our pace…they were not made that way.
Let’s slow climate change. Lets save our wildlife.
Sheryls thoughts on climate change

Dear all, I invited readers and friends to contribute their thoughts on Climate change in the run up to Copenhagen from 6th - 8th December - only 52 days away. It may not surprise many of you that our first guest blogger is Sheryl who writes her own fantastic blog Not Honey: Please don’t tap on the glass.
Climate change decision must include commitment to slow and stop population growth
No one likes to talk about human overpopulation as the number one
crisis facing our planet. Most environmentalists and wildlife
protectors don’t like to talk about it. There’s the idea that having
as many kids as you want is a God-given right and mentioning that
“right” as a cause for climate change and planetary destruction irks
many people.
That silence is deadly. Here the world waits for the U.S. to take the
lead on climate change and the best we can do is a useless
cap-and-trade bill that has no chance of actually limiting greenhouse
gas emissions. There are too many loopholes, including the
“offsets” that industry insists they must have, and no clear plan for just how
many credits for emissions the big polluters can buy. Not included at
all in this bill are greenhouse gases from farms, which emit
35-40 percent of all methane emissions, “(which have 23 times the
global warming potential of carbon dioxide), 65 percent of nitrous
oxide (which is 320 times as warming as carbon dioxide) and 64 percent
of ammonia, which contributes to acid rain” according to the 2006 UN
report “Livestock’s Long Shadow.”
Food production for an exploding human population is a major source of
global warming pollution. There is talk now among wildlife protectors
about designating more wildlife parks and reserves for agriculture and
animal farming. Dr. Richard Leakey, noted anthropologist, wildlife
protector, and head of WildlifeDirect, in an interview for
“Kenya Imagine” said the following:
“Population growth is, as far as I am concerned, is
probably the single most worrying factor for the planet. We can look
at a farm, we can look at a national park – we can say the carrying
capacity of that area is “x.” If we look at the planet, the carrying
capacity for our planet has been exceeded. This planet has too many
people on it. How we address this I don’t know. But I am certain if we
don’t address it, many of the good efforts being made to cut carbon
dioxide emissions and to find alternative sources of energy won’t have
the desired effect. It has got to be linked and conceptualised in a
way that stabilises the human population and ultimately brings the
numbers down.”
Iregi Mwenja, a researcher on WildlifeDirect, has posted more than once about
the threat to wildlife from a growing human population. Recently, he
posted:
“With the population of the world at 9 billion in
2050, we may have 370 million people facing famine
worldwide. FAO says more land is needed to increase food production by
70 percent in 2050. In a country like Kenya where land is scarce now
and famine is the order of the day, the situation will be grave
serious in 40 years time when human population will have grown to over
60 million people. We may be forced to sacrifice some land in our
protected areas to feed this overblown human population! If you don’t
want to contribute to this catastrophe, let us limit the number of
kids per couple to 2. Please read the BBC NEWS
article below for more details on the FAO report.”
Read that again: Food production must increase 70 percent over
the next 40 years to feed the growing human population. What
does that mean?
More factory farms and far more greenhouse gas emissions promoting
global climate change than can be regulated or capped-and-traded. The
BBC story states that “Climate change, involving floods and droughts,
will affect food production.” Climate change is already having a
devastating affect on food production and vice versa.
Thousands of farmers in India have committed suicide because of crop failures
due to drought. Deforestation in the Amazon to make room for
cattle farms and soybean farms to FEED THE CATTLE has caused the loss
of more than 150,000 square kilometers of rainforest in Brazil between 2000-2008.
Loss of forests in the Democratic Republic of Congo is putting
gorillas at risk of extinction, which will put humans at risk of
extinction, too.
How’s that? How can the loss of a fellow Great Ape species have
anything to do with human survival? Turns
out that gorilla dung is a major component in forest growth. We
need rainforests to turn carbon dioxide into clean air and to deter
the greenhouse effect. Gorillas, according to Ian Redmond, the UN
ambassador for the Year of the Gorilla, “are herbivores, feeding on
fruit and plants. The digested food, as it passes through their
systems, helps seeds to germinate. … The full extent of the
gorillas’ role in propagation is unclear. But Redmond said a number of
plant species could not flourish without them, or wild elephants, the
other large mammal crucial in germination.” The gorillas “caught up in
the region’s civil wars, preyed on by poachers, and crowded out of
their homes by mining and logging industries - are already endangered
across Africa. …But Redmond’s argument could help give the animals a
new level of protection.” Economists have suggested spending $15
billion on reforestation as a “cheap” way of cutting greenhouse gas
emissions.
“Redmond said gorillas were crucial in maintaining the lifecycle of
the rainforests in the Congo basin. The forests themselves suck up
more than 1bn tonnes of carbon every year.”
“This is what the species are for. They are not ornaments. They are
not just interesting things to study. They are part of an ecosystem,”
he said.”
We are the only species of Great Apes on this planet who seem not to
know their place in an ecosystem. If we continue to allow human
populations to grow and crowd out all the wildlife until they’re all
extinct, and use up all the forests until they’re gone … what will
we have left? A planet full of nothing but humans and a ruined
environment that can no longer support life.
“It is only if you bring numbers down that we will be able to find a
way for resource utilisation per capita to increase. It is the only
way you are going to deal with poverty and unless you deal with
poverty, the situation can only spiral downwards. This is a massive
problem and the solutions are not simply condoms versus draconian
measures such as one child per family. It has to be looked at in
different countries in different ways. I think there has to be a
commitment everywhere to slow and stop population growth. I do believe
that we have been set back a long way by the opposition to family
planning that is being shown by some of the religious groups and by
some of the more conservative governments such as the current US
administration.” - Richard Leakey, in an interview published during
the Bush Administration
