杂交导致基因污染

In agriculture and animal husbandry, green revolution popularized the use of

conventional hybridization to increase yield many folds by creating

“high-yielding varieties”. Often the handful of breeds of plants and animals

hybridized originated in developed countries and were further hybridized with

local varieties, in the rest of the developing world, to create high yield

strains resistant to local climate and diseases. Local governments and industry

have been pushing hybridization with such zeal that several of the wild and

indigenous breeds evolved locally over thousands of years having high resistance

to local extremes in climate and immunity to diseases have already become

extinct or are in grave danger of becoming so in the near future. Due to

complete disuse because of un-profitability and uncontrolled intentional,

compounded with unintentional cross-pollination and crossbreeding (genetic

pollution) formerly huge gene pools of various wild and indigenous breeds have

collapsed causing widespread genetic erosion and genetic pollution resulting in

great loss in genetic diversity and biodiversity as a whole.

环境保护

Environmental preservation is the strict setting aside of natural resources

to prevent damage caused by contact with humans or by certain human activities,

such as logging, mining, hunting, and fishing. It is different from

conservation; conservation allows for sustainable development, whereas

preservation is complete restriction of development. Regulations and laws may be

enacted for the preservation of natural resources. The Endangered Species Act of

1973 in the United States, for example, was designed to protect critically

imperiled species from extinction caused by the damaging side-effects of

economic growth and development.

导致环保行动复杂化的三大原因

The challenge to orchestrate the changes necessary for environmental

improvement are further complicated in at least three ways. First, there are

conflicting viewpoints as to the role government plays to influence private

industry to replace technologically damaging processes with more

ecologically sound technologies. Second, to phase out current technologies is

a burden many corporations are unwilling to take on; implementation of new

technologies adversely affects profit margins. Third, governmental failures in

policy create a situation where corporations have no incentive to move towards

pollution control. Implementation of governmental policies and programs designed

to improve the environment fail because there is no incentive for legislators to

determine the costs and benefits of their legislation, as there is a lack of

appropriate experience in the matter. Legislators focus only on the appearance

of implementing solutions for the popular vote, and then allow their decisions

to be clouded by lobbyists and political maneuverings. The resulting regulatory

standards and technological mandates inappropriately micromanage the private

sector, limiting their creativity to allocate resources to improve and

change.
