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.

How you imagine the world determines how you live in it.

As parents, grandparents, uncles and aunts we need to start getting out into nature with the young people in our lives. Families play a key role in getting kids outside.

For the sake of our health, our children and grandchildren and even our economic well-being, we must make protecting the planet our top priority.

Nature surrounds us, from parks and backyards to streets and alleyways. Next time you go out for a walk, tread gently and remember that we are both inhabitants and stewards of nature in our neighbourhoods.

Each of us now has 2.27 kg (5 lbs) of plastic embedded in our bodies.

You are what you do, not what you say.
