Rich farmland makes Canada a major agricultural nation, exporting about half of what it produces. Thus, Canada was among the first countries to regulate industry and establish laws discouraging pollution and environmental degradation. Canadian engineers have developed environmentally-sound technologies and solutions for pulp and paper mills, mining operations, oil wells, hazardous waste disposal and many other industries. It is also one of the top five employers in Canada with an estimated 4,500 companies employing 92,000 people. Sustainable development is the goal of Canadian industry.
Reforestation is an ongoing commitment.
In British Columbia, for example, three seedlings are planted for every tree that is cut. Most Canadians respect and take responsibility for the environment at an individual level. Recycling of paper, glass and plastic is common in many communities. Canada also takes a leading role in protecting the international environment. Canadian environmental policy and expertise has been adopted in many countries.
