Forests play an important role in the carbon cycle of the
planet, taking
carbon dioxide from the air and putting it into their wood,
roots and the soil beneath them.
According to the New York Times, 12/23/14, humans (that’s us) have cut
down, burned or damaged three-quarters of the world’s forests, which has
accounted for much of the excess carbon that is warming the earth. Scientists
concluded years ago that deforestation must be stopped, to limit climate change
and preserve biological diversity.
According to Nigel Sizer, director of forest programs at the World
Resources Institute, “Every time I hear about a government program that is
going to spend billions of dollars on some carbon capture and storage program,
I just laugh and think, what is wrong with a tree?” Richard Houghton, acting president of the Woods Hole Research
Center, has argued for turning some 1.2 billion acres of marginally productive
agricultural lands into forests.
This could be possible, researchers say, if farming in poor countries
could become more efficient. Dr.
Houghton believes that his target of regrowth and protection of existing
forests could slow the rapid growth of carbon dioxide, or possibly halt
it. This, he believes, would give
the world a few decades for an orderly transition away from fossil fuels
Environmental organizations, such as Greenpeace, and
mounting worldwide pressure, have helped corporate and governmental leaders in
countries with tropical forests to begin to slow the cutting. Forest regrowth is also in the works. Costa
Rica is considered a forest success.
Although much of the country’s old growth forest had been cut down, new
policies encouraged regrowth to cover more than half the country. However, there is a threat to
reforestation - a boom in pineapple farming that gives landowners an incentive
to cut down recovering forest plots.
The pineapples will mainly be exported as a cash crop.
The Amazon, spreading across nine countries of South
America, is the world’s biggest tropical forest. Brazil has cut down millions of acres of the Amazon for
timber, cattle ranching and soybean farming. The soybeans were mainly used to produce meat for Western
fast food companies. After Greenpeace invaded McDonald restaurants and put up
poster of Ronald McDonald with a chain saw, McDonald and other companies pressured
their suppliers to stop buying products linked to deforestation. Pressure from the Brazilian government
and large business groups has resulted in a sharp drop of deforestation, by 83%
over the past decade. The
Brazilian Ministry of Agriculture focused on helping farmers raise yields
without needing additional land.
The carbon dioxide kept out of the air by Brazil’s actions far exceeded anything done in
the world to slow global warming, according to the New York Times article.
Indonesia is the new test case for environmental groups;
deforestation is rampant there – to clear land for the production of palm oil
from a type of palm tree. Palm oil is used in many processed foods – ice cream,
candies, baked goods and even lipstick.
Since the (partial) demise of hydrogenated oils – so called
trans fats – palm oil has been used as a replacement. Despite its high levels of beta carotene, it is not a health
food, as it is a saturated fat that can raise levels of cholesterol. Deforestation of Indonesian forests to
produce palm oil has resulted in serious environmental damage and has put the
Sumatran orangutan on the critically endangered list. Indonesia is working on better forest regulation. This has caused palm oil producers to
move to Africa.
Here is action plan for us, the lowly enlightened eaters. Do not buy animal food if the
animals have been fattened with soybeans – the beans have probably come from
Brazil (and sprayed with Roundup since they are GMO). Soybeans from the US, unless they are organic, are also
sprayed with Roundup, which has endangered the Monarch butterfly by killing
milkweed. 2,4-D is also being used
on US soybean crops. Do not buy
pineapples from Costa Rica – support their ecotourism instead. Read labels very carefully on all manufactured foods, and
don’t buy anything containing palm oil. Support family planning in every way
you can. Population growth is destroying the environment. Plant a tree. Your actions count –
every day! Happy New Year. Feliz y Prospero Año Nuevo.
