Ecoefficiency (measures to minimize environmental
impact through the reduction or elimination ofwaste
from production processes) has become a goal for
companies worldwide, with many realizing significant
cost savings from such innovations. Peter Senge and
Goran Carstedt see this development as laudable but
suggest that simply adopting ecoefficiency
innovations could actually worsen environmental
stresses in the future. Such innovations reduce
production waste but do not alter the number of
products manufactured nor the waste generated
from their use and discard; indeed, mostcompanies
invest in ecoefficiency improvements in order to
increase profits and growth. Moreover, there is no
guarantee that increased economic growth from
ecoefficiency will come in similarly ecoefficient ways,
since in today's global markets, greater profits may
be turned into investment capital that could easily be
reinvested in old-style eco-inefficient industries. Even
a vastly more ecoefficient industrial system could,
were it to grow much larger,generate more total
waste and destroy more habitat and species than
would a smaller, less ecoefficient economy. Senge
and Carstedt argue that to preserve the global
environment and sustain economic growth,
businesses must develop a new systemic approach
that reduces total material use and total accumulated
waste. Focusing exclusively on ecoefficiency, which
offers a compelling business case according to
established thinking, may distract companies from
pursuing radically differentproducts and business
models.

7.The passage implies that which of the following is a
possible consequence of a company's adoption of
innovations that increase its ecoefficiency?

(A) Company profits resulting from such innovations
may be reinvested in that company with no
guarantee that the company will continue to
make further improvements in ecoefficiency.

(B) Company growth fostered by cost savings from
such innovations may allow that company to
manufacture a greater number of products that
will be used and discarded, thus worsening
environmental stress.

请教各位大牛，A为什么不对？我在原文中用红色highlight的段落不就是说“生态革新带来的profit会不能保证会用在有利生态的方面，而有可能会投资在旧的，对不生态的行业里”吗？

相反，B中的比较级，a greater number of我一直没在文中找到。文中只说，并不会改变（do not alter the number），而没有说会更多啊。
