Love is the force that makes us fully human.

Just as fossil fuels from conventional sources are finite and are becoming depleted, those from difficult sources will also run out. If we put all our energy and resources into continued fossil fuel extraction, we will have lost an opportunity to have invested in renewable energy.

Salmon farming-the placement of large metal or mesh net cages in the ocean to grow fish-was pioneered in Norway in the 1960s. Since then, the industry has expanded to Scotland, Ireland, Canada, the US, and Chile, but is dominated by the same multinational corporations. Wherever it is practiced, net-cage salmon farming is controversial and raises serious environmental concerns.

Faced with the evidence, many deniers have started to admit that global warming is real, but argue that humans have little or nothing to do with it.

Beyond reducing individual use, one of our top priorities must be to move from fossil fuels to energy that has fewer detrimental effects on water supplies and fewer environmental impacts overall.

Most North Americans know that human-caused global warming is real, even if political leaders don't always reflect or act on that knowledge.

Doing all we can to combat climate change comes with numerous benefits, from reducing pollution and associated health care costs to strengthening and diversifying the economy by shifting to renewable energy, among other measures.
