SCIENCE MATTERS by David Suzuki with Faisal Moola
Are Canadian politicians finally paying serious attention to the
environment? Recent events give us reason for optimism. On August
1, we wrote about the federal Sustainable Development Act and how
all the political parties put aside their differences to support
this important, new law. Weve also seen a lot of progress
lately on the part of some provincial governments regarding global
warming. The Ontario governments recent commitment to protect
50 percent of its intact boreal forest offers further hope that
governments are getting serious about protecting the planet.
On July 14, Ontario Premier Dalton McGuinty committed to preserving
225,000 sq km of northern boreal forest, under the provinces
Far North Planning Initiative. Thats an area one and a half
times the size of the Maritime Provinces! Its a significant
commitment and its something more than 1,500 of the worlds
scientists had asked for, including us.
The boreal forest stretches across the northern part of Canada,
covering 35 percent of the countrys total land mass. It represents
about one third of the worlds circumpolar boreal system and
one quarter of all intact forests remaining on the planet. The region
supports three billion migratory songbirds and more than 200 species
of animals, including dozens of threatened or endangered species
such as woodland caribou, grizzly and polar bears, wolverine, lynx
and white pelican.
Ontarios northern boreal region makes up 43 percent of the
provinces land mass. Under the plan, half of this massive
region would be protected in an interconnected network of conservation
lands.
The announcement is significant not just in terms of conservation
but also because it marks the first time a government in Canada
has explicitly recognized the role that nature conservation must
play in combating global warming. The boreals forests and
peatlands absorb and store massive amounts of carbon, making them
a hedge against global warming caused by emissions from human activity.
Scientists estimate that Ontarios northern boreal alone absorbs
12.5 million tonnes of carbon dioxide emissions a year.
Its difficult to describe the global significance of Canadas
boreal forest. Its one of the last places on earth where human
activity hasnt yet upset critical predator-prey relationships,
natural fire regimes and hydrological cycles. And economists conservatively
estimate that the ecosystem services provided by the boreal, such
as water filtration, pollination, and carbon storage, have 2.5 times
the economic value of market resources extracted each year, such
as oil, minerals and timber.
As significant as the Ontario governments announcement is,
we have to be cautious in our optimism. For one thing, we dont
know if protecting 50 percent will be enough to conserve the regions
biodiversity. And we have yet to learn what areas will be put off-limits
to development. Fortunately, the government has committed to working
with First Nations in the region to develop comprehensive land-use
plans.
We must also ensure that the government doesnt use its announcement
to protect the sparsely populated and largely unthreatened northern
boreal as justification for further expansion of industrial development
in the southern boreal, which is far more attractive to industries
such as forestry and mining.
The areas not slated for protection under this plan in both
the northern and southern boreal must be managed in a sustainable
way based on sound scientific principles. And the government should
reverse its recent decision to give the forest industry a one-year
exemption from new habitat-protection regulations under the provinces
Endangered Species Act.
Still, with this announcement, Ontario has taken an important and
courageous step, one that we hope other provinces will follow. For
example, Quebec has protected less than five percent of its own
boreal forest, and although it has plans to increase this, it has
yet to make a commitment as visionary as Ontarios.
The recent attention governments have been paying to the environment
is a positive sign. But successful conservation efforts cant
be limited to aspirational goals announced at news conferences.
We all have a responsibility to make sure governments live up to
their commitments.
