World Environment Day

Each World Environment Day is organized around a theme that focuses attention on a particularly pressing environmental concern. The theme for 2017, ‘Connecting People to Nature’, urges us to get outdoors and into nature, to appreciate its beauty and to think about how we are part of nature and how intimately we depend on it. It challenges us to find fun and exciting ways to experience and cherish this vital relationship.

Billions of rural people around the world spend every working day ‘connected to nature’ and appreciate full well their dependence on natural water supplies and how nature provides their livelihoods in the form of fertile soil. They are among the first to suffer when ecosystems are threatened, whether by pollution, climate change or over-exploitation.

Nature’s gifts are often hard to value in monetary terms. Like clean air, they are often taken for granted, at least until they become scarce. However, economists are developing ways to measure the multi-trillion-dollar worth of many so-called ‘ecosystem services’, from insects pollinating fruit trees to the leisure, health and spiritual benefits of a hike up a valley.

Every World Environment Day has a different global host country, where the official celebrations take place. This year it is Canada.

Its rich and spectacular natural heritage is a source of pride and identity for Canadians. Abundant natural resources also support the country’s economic prosperity – through tourism as well as sustainable use – and the health and well-being of its 36 million inhabitants.

World Environment Day is an important part of Canada’s 150th birthday celebrations. As part of the festivities, Canada offers free passes for its national parks throughout 2017.
